Mega Micro Chuck: For micro drills and end mills

Mega Micro Chuck

Mega Micro Chuck's 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. A slim nut and taper design prevents interference in applications with micro drills and end mills.
