Powerful Clamping Force

Deflection test to compare with other manufacturer’s milling chuck proves that Mega Double Power Chuck has achieved 1.4 times higher rigidity.

Achieves High Rigidity as an integral Body

In the case of a conventional milling chuck, the inner taper of the nut contacts only with the body when tightened. However, there is still a gap between the nut and body. The large fit diameter of the nut provides higher rigidity as if the chuck and nut were an integral body. This superior rigidity assures heavy cutting without chatter.

Original design of notch-free nut prevents
vibration and noise

Vibration at high speeds is eliminated by a notch-free nut which offers superior balance and concentricity. This ideal nut design not only eliminates whistling noise and coolant splattering, but also assures increased strength of the nut itself.

Easy and firm clamping with the Mega Wrench
