Types of CNC Milling Tools

In modern CNC machining, aluminum alloy is a lightweight material with excellent thermal conductivity and low cutting resistance, widely used in aerospace, automotive, mold making, and electronics industries. However, machining aluminum is not as straightforward as “soft material equals easy machining,” especially in high-speed milling or mirror finish applications. Improper tool selection can easily lead […]

In modern CNC machining, the corner radius milling cutter (also known as an R-angle end mill) has become one of the most commonly used tools for machining hardened steel and aluminum alloys due to its combination of strength and superior surface finish. Compared with traditional flat end mills, a corner radius milling cutter features a

In modern CNC machining, corner radius end mills are a type of multifunctional tool that combines the characteristics of both square end mills and ball nose end mills. They are widely used in mold manufacturing, part finishing, and edge transition processing of high-hardness materials. The core feature of this tool is the fixed-radius fillet (R

In modern CNC machining, aluminum alloys are widely used in aerospace, mold making, automotive parts, and other industries due to their lightweight nature, excellent thermal conductivity, and low cutting resistance. However, aluminum machining at high speeds often faces challenges such as built-up edge (BUE), tool adhesion, and poor chip evacuation. Balancing surface finish, tool life,

In modern CNC machining, stainless steel is widely used in critical industries such as aerospace, automotive manufacturing, and medical devices due to its high strength, excellent corrosion resistance, and tendency to work harden. However, stainless steel’s toughness and low thermal conductivity also pose significant challenges to tooling. Improper tool selection or usage often leads to

In modern CNC machining, the square end mill has become one of the most commonly used general-purpose tools because it can handle multiple tasks such as slotting, side milling, and planar machining. Whether quickly removing large amounts of material during rough machining of steel parts or achieving high surface quality in finishing, reasonable planning of

In modern CNC machining, the flat end mill is one of the most commonly used and versatile cutting tools. Thanks to its straight-tip design, it is widely used for grooving, contouring, and face milling operations on both metal and non-metal materials. Compared to ball nose end mills, flat end mills offer more precise vertical cutting,

In the field of CNC machining, the bull mill cutter (also known as bull nose end mill cutter or bull nose milling cutter) is a multifunctional milling tool that combines the strength of roughing with localized finishing capabilities. Its tip features a small-radius transition that effectively reduces stress concentration and improves durability compared to traditional

When machining high-hardness steel, especially mold steel, tool steel, or high-speed steel workpieces above 60 HRC, tool selection becomes critically important. General-purpose end mills often fail under such demanding conditions—rapid wear, chipping, or breakage due to high cutting resistance, extreme temperatures, and hardened microstructures. This can significantly impact efficiency, surface quality, and overall cost. Therefore,
