Solid Diamond End Mill Flat End, Ball End, and Radius Tip
Solid diamond end mills with flat end, ball end, and radius tip are manufactured from polycrystalline diamond grains to deliver maximum hardness and wear resistance. Their diameters range from 0.2 millimeters to 12 millimeters, with overall lengths between 40 and 100 millimeters. The surface hardness of diamond is around 98 HRA, enabling machining of ultra-hard materials such as silicon carbide, titanium alloys, and carbon fiber composites. Cutting speeds can reach up to 1000 meters per minute while maintaining dimensional accuracy within 0.005 millimeters.
Flat end types are used for creating smooth surfaces and precise slots, while ball end mills are ideal for 3D machining and mold manufacturing. Radius tip end mills are produced with edge radii ranging from 0.2 to 3 millimeters, providing greater strength in continuous operations. The helix angle is typically designed between 30 and 45 degrees to optimize chip evacuation. Thermal resistance up to 1100 degrees Celsius can be achieved with CVD or PVD coatings. These tools are manufactured in compliance with ISO 513 and DIN 6527 standards and are widely used in aerospace, mold making, and medical industries.
