VC HOLDER with TiN BEARING NUT This is the Mighty End Mill Holder from the series of Tin Bearing Nut type collet chuck to satisfy the gripping torque, run-out accuracy, cutting rigidity, high precision finish and high speed rotation. tooling can be used as the BT double face contact tooing on the machine with the BT double face contact spindle. It can be also used as the BT tooling on the machine with BT standard spindle.

JAPAN, USA, EU, KOREA PAT.

Power of TiN Bearing Nut Good sliding effect due to the surface hardness of HV2,200. More efficient than conventional ball bearing built-in nut.

8 deg. internal taper proven with the Slim Chuck for the accuracy and gripping torque.

Simple external design without the notches to be tightened with GH handle Ultra high speed rotation

?

Unstable accuracy caused by tightening torque and the possibility of rust.

The Tin coated bearing plate reduced friction. This is the best for the thrust load.

TiN Bearing (Hardness : HV2,200)

Pilot shank on the collet for further stability of the accuracy.

The thick wall design of the VC Holder body improves its cutting rigidity.
