The high hardness and oxidation resistance of the revolutionary TH Coating ensure excellent performance and long tool life in 40-55HRC hardened steels such as H13, D2, and A2 as well as pre-hardened steels. High heat resistance makes TH Coated tools suitable for dry cutting.
Nano-crystal technology helps to reduce the friction-resistance of the coating while maintaining the hardness. This reduction in friction decreases tool wear and also makes dry cutting possible.

- For slotting, please refer to the chart above regarding the depth of cut for slotting.- For side milling, please increase RPM to 1~1.3 times and Feed Rate to 1~1.5 times of the figures in the chart above.- The RPM generally used for slotting is used for spot facing, just lower the feed rate by about 20%.
