Feature：
-It is ideal for a variety of machining applications including boring milling,reaming,tapping and grinding.
-Material:SUJ2
-HRC46 degree
-SK Collet designed with 8 degree cone angle which shortens the suspended length of a collet,-therefore,the clamping power is huge.
-the tolerance of the clamping tool is limited during H7
-the hollow diameter is smaller than 3mm,its elastic contract is 0.25mm
-the hollow diameter is larger than 3mm,its elastic contract is 0.5mm
-Accuracy:T.I.R.＜0.005mm UP Grade.
