1. HIGH HARDNESS: Adopt 20CrMnTi steel material, quenched and hardened, possess high hardness and strong wear
2. FINE CONTROL PROCESSING: The inside and outside of the tool holder are integrally formed. Fine control processing bring more and high concentricity
3. MACHINE TOOL PROCESSING: After inner hole ground treatment, suitable for machine tool processing and has a longer life than ordinary tool holders
4. CARBURIZING AND QUENCHING PROCESS: Adopt carburizing and quenching process, the hardness is higher, the fatigue of the interface is stronger and more
5. 0.005MM : The clamping range from 1‑7mm, and the accuracy is equal or less than 0.005mm, very trustworthy. 10000rpm speed can realize fast
