- Pointed part made from high speed steel (HSS), quenched hardness 55-60 HRC for wear resistance and durable point geometry - Bearing design uses a high precision bearing for improved accuracy and stable cutting performance - Dust proof seal prevents cutting dust and debris from entering the bearing, extending service life and reducing maintenance - Designed for lathe work in medium speed and medium load environments for reliable everyday use - Suitable for high speed turning and compatible with CNC lathes, enabling both standard and high speed operations Use scenarios - On a conventional lathe, turn medium diameter hardened steel shafts with tight tolerances, benefitting from accuracy and durable tip geometry - On a CNC lathe, perform high speed turning of alloy components where precision and finish quality are critical - In dusty cutting environments or long duration runs, the dust seal helps maintain bearing performance and reduces downtime
