Mega Micro Straight

Mega New Baby Chuck

A slim nut prevents interference in applications with micro drills and end mills. Mega Micro Chuck's original design of a notch free nut prevents vibration and noise and 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.

The clamping range has been expanded to an 8mm capacity and a sealed nut for directed coolant delivary has been made available (6S and 8S body sizes only).
