Feature:
1. This recessed table design on the front of the chuck cone prevents the direct entry of dust and iron chips during work, which affects the accuracy of the tool holder.
2. The slot of the collet hole adopts a grinding process, which is suitable for high?speed processing.
3. After cryogenic treatment, the wear resistance of the collet is significantly improved.
4. The accuracy and life of the repeated chuck can be increased by about 50percent , and the performance is stable.
5. Used in milling, boring, drilling, tapping operations or various CNC, engraving machines and other equipment.
