HS Series Ball Cutter

Product Details

1. Application – Applicable to the semi-finishing and finishing machining of face milling and R-angle contour milling for steel after quenching with a hardness of HRC 48 – 52°.
2. Substrate – This end mill is made of nano-grained tungsten carbide, which significantly improves wear resistance and greatly prolongs the tool life.
3. Coating – The PVD coating equipment of Kobe Steel in Japan has been introduced, and a multi-layer composite coating is adopted to ensure the high stability and high-efficiency performance of the coating.
4. Precision – Our products offer excellent precision. The accuracy of fillets and ball nose R is controlled within ±0.005 mm, the contour accuracy is ±0.005, and the shank diameter tolerance is at the h5 grade.
