https://youtube.com/shorts/NGQciC-0QOw In the modern manufacturing landscape, titanium alloys are widely valued in aerospace, medical devices, and precision tooling for their exceptional strength-to-weight ratio, corrosion resistance, and high-temperature performance. However, drilling titanium alloys remains a technical challenge: their low thermal conductivity and chemical reactivity make them prone to tool overheating, material adhesion (stick‑on), and even tool […]

In modern CNC machining, the accuracy of drilling directly affects the stability of subsequent processes and product quality. In the pre-positioning operation before drilling, Spot Drill and Center Drill are often mentioned and easily confused. When choosing a drill, many engineers often ask: “What is the difference between spot drill and center drill?” and “Which

In mechanical processing and everyday manufacturing, drill bits are fundamental cutting tools, available in a wide range of types and specialized designs. Whether it’s HSS drill bits and carbide drill bits for metalworking, or step drill bits and spot drills for sheet metal and plastic, choosing the right type of drill bit directly impacts machining

In modern manufacturing, especially in CNC precision machining, carbide drill bits have become essential tools for cutting various metals due to their high hardness, excellent wear resistance, and consistent performance. Compared to traditional high-speed steel (HSS) drill bits, carbide drill bits offer superior cutting efficiency and longer tool life when machining difficult materials such as

In metalworking, whether for CNC mass production or everyday maintenance and DIY tasks, selecting the right drill bit for metal is crucial to ensure processing efficiency and hole accuracy. With a wide variety of metal materials—ranging from stainless steel, carbon steel, and aluminum alloys to titanium—the performance, durability, and heat resistance of different drill bit

In the field of machining, stainless steel is widely recognized as a “high-strength, difficult-to-machine” metal. Due to its excellent corrosion resistance and high toughness, stainless steel demands higher standards in the drill bit’s material, geometry, coating, and chip evacuation design during drilling. Choosing the best drill bit for drilling stainless steel directly impacts machining efficiency,

Drilling hardened steel has always been a significant challenge for CNC engineers due to the material’s high hardness, strength, and poor thermal conductivity. Ordinary drill bits often fail to handle these demands, causing issues such as tool burning, edge chipping, and hole positional errors during machining. Choosing the right drill bit designed specifically for hardened
