The HM Series 2-Flute Carbide Ball Nose End Mill is designed for precision 3D contouring and finishing of hardened materials (48–65 HRC), including die steel, tool steel, and high-speed steel.
Each tool is fully inspected to ensure ball radius accuracy within 5μm tolerance for excellent dimensional control and surface quality. Micro-edge honing enhances edge strength, reduces chipping, and extends tool life.
Suitable for dry, oil, or wet cutting, it is optimized for high-speed machining centers and ideal for high-precision mold and die applications requiring superior finish and durability.
