1.Used for high precision machining ,no clamping nut required,avoiding the interference of workpiece during maching .
2.The design of collet pull,stronge rigidity,higher stability.
3.-196℃ long cryogenic treatment ,reduce residual stress,wear resistance improved significantly .
3.Super long stereotypes heat can effectively remove the residual stress during the grinding processing .
4.Balance G2.5/G6.3 for choose .And each handle is equippen with a spanner.
