Unlocking the Potential of Flat Bottom Drill Bits for Precision Drilling

The flat bottom drill bits are a momentous improvement in the field of accurate drilling, offering an unmatched level of exactitude and efficiency to various drilling tasks. Designed for making holes with flat bottoms, these bits are ideally suited for such processes that necessitate precise and accurate depth control with minimal deviation. This paper seeks to extensively discuss the features of these kinds of drill bits, their operational advantages as well as what they enhance. Knowledge about particular characteristics and capacities inherent in these tools can help users fine-tune drilling operations leading to high-quality precision and productivity increase with cost-effectiveness.

Why Choose a Flat Bottom Drill Bit Over Traditional Bits?

The Advantages of Flat Bottom Design in Drill Bits

The first advantage of utilizing flat-bottom drill bits stems from their unmatched ability to make accurate holes without subsequent operations. In numerous precision engineering works, traditional drill bits often leave a cone shape at the hole’s bottom, which is undesirable. This saves time because it eliminates additional finishing processes and reduces tool wear, thus improving the overall efficiency of the process. The other attribute that makes these tools more interesting to use is their structure, which allows them to be used in various applications, such as drilling on non-flat surfaces and drilling materials that require high precision. Their sturdy nature prevents deflections, resulting in uniformity among the holes, an important feature for high-tolerance industries. Thus, they can have a great impact on the quality and consistency of work if adapted to flat bottom drill bits, demonstrating their role in precision drilling work.

Comparing Flat Bottom Drill Bits to Twist Drills and Forstner Bits

The use of flat-bottom drill bits should satisfy several critical parameters in relation to twist drills and Forstner bits as applied in specific cases. Firstly, they are twisted drills, which allow deep holes to be drilled into a wide range of materials. However, these tools usually leave a conical bottom on the hole and possibly are not good for creating flat bottom holes. On the other hand, Forstner bits are very precise in making flat-bottomed holes and, hence, most recommended in woodworking applications where there is minimal tear-out. However, twist drills have more possibilities when it comes to material usability; also, their design limits them in terms of depth capacity.

Flat bottom drill bits were mentioned earlier today as having some advantages over both twist and Forstner bit styles:

• Precision: They outperform twist drills by producing perfectly flat-bottomed holes that do not need any post-drilling finishing work.
• Versatility: The range of materials that can be worked with is wider for flat bottom drill bits than it is for Forstner-bit style ones.
• Efficiency: In comparison with twist drills, they eliminate additional operations such as reaming frequently done at the later stages thus saving time and consuming less tooling life.
• Consistency and Stability: With uneven surfaces or off-center locations being encountered when drilling using either twist or Forstner bits but this may deflect less during operation due to their design.

Narrowing down to the type of hole required, material being drilled into as well as the importance placed on precision and efficiency will enable choosing among flat bottom drill bits, twist drills, or Forstner bits.

When to Use a Flat Bottom Bit for Your Drilling Projects

Precision and efficiency in various drilling projects demand finding the best instant to use a flat bottom drill bit. This is why I think they are the most effective tools when it comes to accurate results and fine finishes especially in creating holes that need no further finishing. For instance, these bits are indispensable for instance in wooden dowel hole creation or in making recesses of hardware on cabinetry that need exact dimensions of the hole’s diameter and depth. Also, their ability to handle an array of materials, be it hardwood or metal, makes them a preferable option for tasks requiring flexibility. Similarly, within time-constrained manufacturing settings where tool longevity is crucial, these bits’ unique structure greatly minimizes the need for secondary operations, consequently leading to faster production cycles as well as reduced wear on tools. In brief, flat-bottom drill bits should be chosen if precision, versatility, efficiency, and stability are some of the key requisites of a project.

What to Look for in a High-Quality Flat Bottom Drill Bit?

Materials Matter: Carbide vs. HSS Flat Bottom Drill Bits

The main difference between carbide drill bits and high-speed steel (HSS) flat bottom drill bits is in their endurance, cutting ability, and suitable range of applications.

Carbide Flat Bottom Drill Bits: These are known for being very hard, which means that they last a long time. What makes carbide special is that it is excellent at staying sharp for a long period of time. This allows it to drill through tough materials like stainless steel and cast iron efficiently. The hardness of carbide allows one to operate these drills at higher speeds than HSS ones, thereby increasing productivity greatly. However, the cost of this durability and performance is higher; hence making carbide a more expensive investment in the beginning. They are preferred in mass production setups as their lifespan compensates for high initial costs over time.

HSS Flat Bottom Drill Bits: Although not as hard as carbide, HSS combines toughness with heat resistance without loss of softness. For this reason, they have become very versatile and hence can be used for drilling wood, plastics, or soft metals such as aluminum, among other things. HHS has the advantage of being cheaper than carbide altogether in the first place. They are ideal when working on all-purpose drilling tasks involving low production or when materials to be worked on do not call for superiority, such as those made from tungsten.

Primary Parameters for Selection:

1. Material Hardness: When dealing with harder materials all the time go with carbide because it outperforms others by far.
2. Production Volume: In case operation involves high volumes then frequent tool replacement becomes unnecessary due to its strength.
3. Cost Consideration: Upon considering cost factors, HSS best suits low-end operations and less resistant raw materials.
4. Speed Requirements: Carbides allow industrial processes to move faster, thus enhancing productivity levels in many industries.

In conclusion, deciding whether to use an HSS or Carbide flat bottom drill bit depends upon an assessment of specific project requirements such as the hardness of materials being drilled, intended usage volume, financial constraints, and level of output expected.

Understanding the Importance of Bit Size and Flute Design

The efficiency and output of drilling operations are influenced by the selection of the size of drill bits and flute designs. Of course, I must be careful in selecting not only a proper diameter for the bit but also comply with hole specifications. The precision in choosing a bit size is directly related to the quality and accuracy of a resulting hole that does not just affect the fit but also affects the functional integrity OEM parts.

On the other hand, flute design plays an integral role in chip evacuation and heat dissipation during drilling. Properly designed flutes facilitate effective evacuation of chips, thus preventing any material build-up within drilled holes, which may cause sticking or even snapping of the bit. In addition, optimal flute designs enable efficient heat distribution; this prolongs life span of drills by minimizing thermal stress. When dealing with hard materials or high-volume manufacturing, flute choice is critical because it leads to increasing thermic and physical constraints upon these bits.

These principles give us confidence that our drill bits will last long as well as perform better while also ensuring that drilling activities remain safe and reliable for both industrial applications or crafts work.

Key Features of Drill Bits for Metal, Wood, and other Materials

The most important thing is to select the right drill bit for different materials in order to achieve optimum performance and lifespan of the tool. For metal applications, I would suggest using high-speed steel (HSS) or cobalt alloy bits. HSS drill bits offer flexibility and can be used for drilling general purpose holes on many metals including iron and steel. On the other hand, cobalt bits are preferred as they have excellent temperature resistance and long life, making them ideal for hard metal drilling such as stainless steels.

When it comes to drilling into wood, look for a pointed tip and wide flutes. The pointed tip is called brad point and it ensures accurate drilling with reduced wanderings. Wide flutes are advantageous in that they ensure efficient elimination of wood chips enabling heat dissipation as well as making the process faster and smoother.

For materials like concrete and masonry, go for carbide-tipped drill bits. Such kind of a bit has a carbide tip, which provides the needed hardness to penetrate through tough materials while its design helps remove dust, thereby preventing damage to the bit itself, resulting in uniform hole diameter.

To sum up, choosing a proper drill bit entails taking note of special features associated with material being drilled through and then selecting a bit that caters for such peculiarities. This means that beside being effective & efficient during drilling function, this also makes sure that user’s safety is achieved besides protection of underlying substance from destruction.

Mastering the Use of Flat Bottom Drill Bits in Woodworking and Metalworking

Best Practices for Drilling Flat Bottom Holes in Wood

Drilling flat-bottomed holes in wood requires a high degree of precision and comprehension both the material as well as tools. Below are some guidelines that could be followed by an ardent woodworking hobbyist or a professional to achieve perfectly flat-bottomed holes:

1. Choose the Appropriate Drill Bit: Either spade bits or Forstner bits are ideal for making flat-bottomed holes. When drilling, Forstner bits provide accurate results and neat edges while spade bits are cost-effective options suitable for bigger sizes of holes.
2. Make Your Workpiece Secure: Stability is essential. Clamps should be employed to hold the wood tightly onto your work table, thus reducing possible movement of the wood and creating a more accurate hole.
3. Setting the right speed: The speed of one’s drill press or handheld drill should correspond with the size of bit and type of wood being used. Bigger bits on harder woods require lower speeds so as not to overheat them.
4. Incorporate a Backing Board: A piece of scrap can be placed at the backside of your workpiece to reduce tear out when the bit goes through it. This backing board should also be clamped down.
5. Frequent Chip Clearance: Especially in lengthy holes, remove your drill bit to get rid of chips constantly from time to time. It prevents overheating by bit and also guarantees a clean hole.
6. Practice Makes Perfect: On scrap before trying this on your actual project, practice first with piece of timber. This allows you to learn about how this tool operates so you can adjust without ruining your main project during the first approach.

With these steps carefully observed, one can be guaranteed good quality results while carrying out drilling flat bottom holes in woods that combines fine precision with aesthetics characteristic of art itself.

Techniques for Efficient Metal Drilling with Flat Bottom Bits

To maximize efficiency, accuracy, and safety when drilling into metal using flat bottom bits, a number of crucial elements must be taken into account. My years of experience in this industry have enabled me to pinpoint the major methods that have the potential to dramatically improve drilling:

1. Choosing the Right Bit Material: In metal drilling, cobalt, carbide or high-speed steel (HSS) bits are recommended due to their toughness and heat resistance. Cobalt bits are particularly useful when it comes to drilling harder metals like stainless steel.
2. Use of a Cutting Fluid: The application of a cutting fluid or oil is necessary when working on metal surfaces while carrying out drilling operations. Not only does it reduce friction but also it helps to preserve your drill bit for longer periods. For most metals, general purpose cutting fluids work well although there may be specific formulations suggested for hard metals.
3. Keep speed low & raise pressure: Metal drilling requires lower speeds than wood drilling so as minimize the heat generated by friction. However, higher pressures should be maintained throughout so that bit enters into metal more efficiently. Exact speed and pressure depends on how hard and thick the metal is.
4. Utilization of a Guide Hole: Beginning with a smaller drill bit to create a pilot hole can significantly enhance accuracy while undertaking this task. This first hole acts as an anchor point for guiding the flat bottom bit hence reducing chances of wandering off target by the same or other drill bits.
5. Frequently cool downtime:regularly ceasing drilling activity gives time for both the bit and metal surfaces to cool down, thus avoiding overheating, which can ruin both the material and the tool itself.Occasionally adding more cutting oil during such breaks would help in cooling plus lubrication purposes.
6. Peck Drilling Method: When dealing with deeper holes, pecking technique can be very effective- it involves partial penetration followed by chip clearance before proceeding further. Removal of chips in this method enables continuous use without clogging which maintains efficient drilling and prolongs bit life.

Following these strategies meticulously would help optimize the process of flat-bottom bit metal drilling to ensure both effectiveness and safety. In addition to these pointers, it usually decreases equipment tear as well as damages that are not necessary thereby improving results.

Adjusting Speed and Feed for Optimal Drilling Performance

Optimal metal drilling performance necessitates speed and feed adjustments on the machine to extend tool life. To determine the best RPM (revolutions per minute) for a drill bit, its diameter must be considered in conjunction with the hardness of the material, using formulae or following the manufacturer’s recommendations. When it comes to feed rate – how deep the tool advances with each revolution – slower speeds are recommended generally for harder materials to reduce bit wear as well as overheating. Precise fine-tuning makes it easier for both parameters to obtain a balance between cutting efficiency and wear on the drill bit. One should always monitor excessive wearing or heating during drilling and adjust speed and feeds accordingly. By making such changes conscientiously, one can significantly improve precision, outcomes and longevity of tools used in professional drilling activities.

Expanding Your Toolbox: Must-Have Flat Bottom Drill Bits for Machinists

 

From Carbide Flat Bottom Drills to Cobalt Drill Bits: A Machinist’s Guide

When choosing between carbide flat bottom drills and cobalt drill bits, it is important to consider various critical parameters that affect drilling performance, tool life expectancy, and overall efficiency.

Material hardness first plays a crucial role in the determination of the right drill bit for the job. The exceptional hardness and wear resistance of carbide flat bottom drills make them ideal for drilling in tough materials. On the other hand, cobalt drill bits are harder also but they can be used on both hard and soft materials equally efficiently.

Heat resistance is another key aspect. Carbide drill bits remain sharp and hold together well even at very high temperatures making them perfect for hot operations. This property is essential in high speed drilling or boring activities involving materials that generate much heat. High temperature resistant properties of Cobalt bits make them suitable for such strenuous conditions as well, although they may not reach the temperature extremes achieved by carbide.

Another factor is cost effectiveness; generally, carbide bits have a longer lifespan due to their ruggedness, but this comes at a higher initial price. Cobalt bits offer cheaper alternatives to carbides hence they are suitable when machining tasks do not require extreme performances.

Lastly application specificity should be considered while selecting the appropriate tools. For applications that require accuracy and efficiency in challenging materials, carbide flat-bottom drills are better than others. Broader ranges of use, which involve various materials under different conditions, favor cobalt ones because they come with an economical cost.

In short, therefore, it all depends on how these elements align with each specific machining task one has to undertake, whether to go for either carbon or cobalt-made tools. Material hardness alone cannot be relied upon without considering factors such as heat resistance as well as cost and application specificity among others hence being guided by these four factors can help machinists select proper tooling solutions needed to satisfy particular requirements.

Comparing Shank Drill Bits and Forstner Bits for Precision Work

To determine the appropriateness of Shank Drill Bits and Forstner Bits for specific tasks, several important parameters need to be considered.

Design and Purpose: Shank drill bits, whether straight or tapered, are primarily designed for drilling cylindrical holes. They can be used in a broad range of materials due to their versatility. Meanwhile, Forstner bits are specialized for creating flat-bottomed holes that can drill overlapping holes or edge holes in materials without tearing them apart.

Precision and Finish: In the case of Forstner bits, their ability to produce clean-cut, precise holes with smooth walls and flat bottoms makes them perfect for fine woodworking where precision is an important factor. This implies that shank drill bits may not offer the same level of finishing but they stand out in drilling through-holes and pilot holes very effectively.

Materials: Depending on the bit type (e.g., HSS, cobalt, carbide), shank drill bits can work well with a wide variety of materials such as wood, metal or plastic. While working on wood and other composite materials where its unique design feature matters most Forstner bits come handy.

Speed and Heat Generation: Shank drill bits that are made from high-speed steel (HSS) or have coatings specially applied resist high-speed operations and dissipate heat efficiently. On the other hand, because they have wider cutting surfaces than others do Forstner bits operate slowly hence careful management of heat is needed to avoid compromising the integrity of the bit resulting into a material’s finish being affected negatively.

Costs And Longevity: Considerably more expensive than basic shank drill bits due to their specific application, and build-up generally sums up most Forstner bits. However, it depends on how much precision is required in addition to what kind of finish quality one wants around his project vis-à-vis cost. Moreover, proper utilization and preservation measures coupled with selecting proper material mixtures give life to the bits afresh.

Concluding, depending on hole quality desired, the type of material being drilled and project’s outcome which calls for accuracy as well as finish, the choice between shank drill bits and Forstner bits in precision work should be based on the specific requirements of each task.

Selecting the Right Drill Bit Set for Your CNC and Machining Needs

To select the best drill bit set for use with your CNC or milling machines, you must have a deep understanding of your project’s peculiarities and the materials in use. Begin by looking at dominant types of materials you will be using such as metal, wood, or composites; this will help you choose bits that perform optimally with them. For any material, one may opt to use high-speed steel (HSS) bits while cobalt and carbide ones are advised when dealing with harder materials since they do not wear out fast.

Secondly, attention should be given to the degree of accuracy required. In terms of woodworking jobs requiring fine finishes and high precision, consider Forstner bits; however there is no need for complicating things in less critical metallic works which can easily be done by twist drill bits. Your choice will also rely on the material that needs specialized holes in it including countersunk and counterbored ones.

Last but not least, compatibility with your CNC machine or drill press is essential. These include shank sizes and whether they are straight or tapering to fit into a chuck or collet on your machine. Purchasing a complete set having various sizes and types might allow future projects to have varying possibilities while ensuring that each drill should have qualities necessary for productivity, long life span as well as good workmanship. Therefore these considerations shall guide you into choosing an effective drilling kit accordingly for machining necessities.

Troubleshooting Common Issues When Using Flat Bottom Drill Bits

Why Your Drill Bit Isn’t Cutting: Tips for Avoiding Dull Bits and Burrs

When confronted with issues like a poorly performing drill bit, the first thing to consider is its dullness. This commonly results from bits that do not cut well hence increasing friction, producing excess heat, and therefore accelerating wear and tear. To avoid your bits becoming dull, you have to take care of them regularly through cleaning and sharpening. Having them sharpened by an expert or using a drill sharpener will ensure that they are still able to function in their cutting role.

Furthermore, this process can be used to minimize burrs which are small raised edges or pieces of material remaining attached to the workpiece after drilling Choosing the right drill bit for the material being worked on and making sure it rotates at the appropriate speed can minimize burr formation as well as reduce it High speed steel (HSS) bits are suitable for softer materials while cobalt or carbide ones may be required when harder materials are being worked on so as to prevent bit dulling and decrease burr formation.

Another important factor is doing things correctly. Using the correct amount of pressure and maintaining smooth regular speeds during drilling greatly minimize burs production which makes a cutter blunt. Finally, whenever you undertake any metalwork project, use cutting fluid/coolant so that there is no heat build-up leading to damaged edges; rather, help extend the sharpness of the drill’s point, thus extending life in general. By following these practices, longevity and cutting efficiency of your drills will be improved significantly leading to smooth and exact precisions in your drilling activities.

How to Sharpen Your Flat Bottom Drill Bits for Extended Life

Your flat bottom drill bits need sharpening to maintain their lifespan and functionality. This process has some key parameters that must be carefully followed for effective sharpening. First, check the bit to figure out how dull it is or whether it is damaged as this will dictate how you will go about in sharpening.

1. Cleaning: Begin the process by cleaning the bit properly so as to eliminate any debris or oil that may disturb the sharpening of bits. Use a brush and cleaning solvent for this purpose.
2. Inspection: Tip and edges should be inspected for wear. Knowing exactly where the bit is dull will help in focusing your sharpening efforts effectively.
3. Secure the Bit: To tighten the bit while being sharpened, a vise or specialized drill bit holder can be used with precision and safety during process.
4. Choose the Right Sharpening Tool: A drill bit sharpener or bench grinder equipped with a fine-grit wheel is suitable for sharpening flat bottom drill bits. Check that it operates well and has been setup correctly before starting off on this task.
5. Adjustment to Relevant Angle: Flat bottom drill bits should be re-sharpened at their original angles which usually range between 118°-135° . Adjust your sharpening tool using an angle gauge if necessary.
6. Sharpening: Softly push the piece against sharpener and move it around either circularly or from side-to-side depending on what type of sharpener you are using in order to remove blunt edges and create new one (sharp edge). Therefore, effective sharpening requires maintaining its initial geometry all through.
7. Cooling: Occasionally cool down your piece into water/coolant oil so as to keep away any overheating that could cause temper loss thereby softening metal.
8. Checking: During this process check frequently for sharpness, geometry etc. If satisfied deburr and clean up your work piece/bit after use.
9. Testing: For confirmation purposes, test on scrap material just before resuming its normal use. With that, you will know whether the bit was sharpened adequately and is functioning as expected.

By following these detailed steps, you can effectively sharpen flat bottom drill bits, extending their life and preserving their cutting efficiency. Bear in mind that a well-maintained drill bit means regular maintenance and correct usage as important as keeping your drill bits in good shape through sharpening.

Solving the Problem of Inaccurate Hole Dimensions and Rough Surfaces

Using blunt bits or wrongly sharpened ones, and inappropriate drilling parameters tend to produce rough surfaces and dimensions of holes that are not accurate. Such issues can be mitigated by starting with ensuring the right sharpening of your drills as per the above guidelines. In addition, it is crucial to choose the appropriate drill bit for your material and use correct cutting speeds and feed rates.

When drilling, it helps in having more precise hole dimensions if you apply a moderate force at a constant speed so as to keep the bit straight. Moreover, the use of cutting fluids can minimize friction and heat buildup thus extending drill life while reducing galling and smearing on workpiece surfaces.

Finally, conduct post-drilling analysis always. If there is still some concern on roughness; consider using better quality drilling tools or reamers for finishing processes. By following these approaches, it will ensure optimum performance during drilling process and solve major problems associated with inaccurate hole sizes and rough areas.

Advanced Techniques and Tips for Drilling Perfect Flat-Bottom Holes

Creating Intersecting Holes and Counterbores with Precision

Making precise intersecting holes and counterbores is a very important task that has to be done with extreme care, particularly when targeting high precision in engineering and manufacturing environments. Some of the things I always have in mind include:

1. Pre-Drilling Considerations: This needs a clear part’s blueprint, including every intersection angle and dimension prior to starting the drilling procedure. This will help me plan the drill path and avoid any possible crashes or misalignments.
2. Tool Selection: The right drill bit for material being drilled and type of hole required is crucial. For instance, I often use a secondary operation piloted counterbore tool when making intersecting holes as well as counterbores so that it can align with the primary hole.
3. Machine Alignment: It is another critical step to ensure that drilling machine or press is properly aligned. Misalignment may result into inaccuracies related to hole position and angle. The machine configuration should always be checked again using accurate measurements.
4. Drilling Speed and Feed Rate: Choosing the right speed (RPM) and feed rate for a particular material matters most in this case. Higher speeds or slower ones may affect accuracy of the hole hence its surface finish too. I usually refer back to manufacturer guidelines before settling on these parameters using my own experience.
5. Use of Jigs and Fixtures: Using custom jigs & fixtures can significantly increase accuracy for complex parts with interconnecting holes countersinks etc. These assist in holding your piece correctly while drilling throughout.
6. Coolant and Lubrication: Proper use of cutting fluids not only increases drill bit’s life but also makes surfaces smoother while making dimensions even more accurate than before. For such reasons, I choose specific coolants or lubricants depending on the type of material being drilled.
7. Post-Drilling Inspection: After drilling, I take precise measurements using instruments meant for measuring angles in order to fully assess dimensions of holes obtained as well as their surface finish among any other parameters. In any case, these deviations can be corrected at subsequent finishing operations.

By taking into account these parameters and using thorough technique, creating intersecting holes and counterbores with accuracy becomes a methodical process that yields good results even in the most severe conditions.

Enhancing Your Skills in Flat Bottom Drilling for Detailed Projects

To make flat bottom drilling skills in detailed projects even better, below are the considerate alternative strategies:

• Boost Your Understanding of Material Science: The material you are working on has different intricacies that can greatly affect your drilling options, especially in tough or unusual situations. Constant learning on material properties and their interaction with drilling techniques is vital.
• Try Out Different Cutting Tool Geometries: The geometry of the drill bit plays a major role in the outcome of flat bottom holes. You could improve efficiency and accuracy by testing various geometries and coatings. Tool manufacturers usually deal with special solutions.
• Use CNC Programming for Accuracy: For highly accurate complex works, refining your CNC programming knowledge will give you autonomous control over drilling parameters. Advanced programming techniques can optimize drilling paths, speeds and feed rates which minimizes errors while enhancing finish quality.
• Get Involved in Collaborative Endeavors: Work together with friends and professionals to expose yourself to new methods and technologies. Take part in forums, seminars and symposiums where you mitigate these experiences towards sharing knowledge needed for this.
• Embrace Stringent Maintenance Practices: Performance is highly impacted by the conditions under which a drilling equipment operates. Machines as well as tools require strict maintenance procedures focusing on alignment, calibration as well as clean function to ensure uniformity of quality.

Therefore, through these lines it would be possible to improve one’s competence in flat bottom drilling thereby allowing him or her talk into detailed precision part required projects confidently and competently.

The Art of Drilling Existing Holes Wider with Flat Bottom Drill Bits

The process needs a perfect understanding of material behavior and drilling dynamics in order to expand the existing holes into a wider diameter using flat bottom drill bits. The operation often referred to as “reaming” has to be done with accuracy and extreme carefulness so that there are no common problems such as straightening of tools, irregular sizing and deterioration of the surface finish. It is crucial to choose an appropriate bore bit for different materials being worked on, which should possess sufficient hardness and coating, thus minimizing the wear rates. Moreover, machining at optimal speeds and feeds based on material properties and tool specifications will guarantee uniform enlargement of hole without any hitches. Furthermore, CNC machines can help make this process more accurate by ensuring fine control over drilling parameters. Finally, constant monitoring during drilling and making real-time changes improves the chances of success without harming the workpiece or tool itself. This systematic way illustrates how holes deeper than those made by standard drills may be created using flat-bottom drill bits in professional settings.
