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

The Mega Wrench has a uniquely designed one way clutch
system with a roller bearing and ratchet function and is capable of safely and evenly applying force on the entire nut periphery.

Slit-Through Coolant

Sealed collet nut for coolant-through tools. Remove the PS Ring to supply coolant to the cutting tool periphery.

Coolant and oil mist are securely directed to cutting tool through slits in the collet, greatly extending tool life.

Powerful Clamping Force

Shallow taper and extended clamping length enhances the clamping and self-centering forces for stable performance. Use only a cutting tool shank with exactly the same diameter as collet bore diameter. The tolerance of the cutting tool shank must be within h7.
