A slim nut and taper design 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).

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.
Mega Micro Collet
Compact in size, but excellent clamping force for precision small applications. Wide coverage (dia..018"-.317") is available.
World's smallest interval of clamping:
Mega Micro Collet: Micro Drills & End Mills
Clamping intervals: ø.004" Collet class: AA Runout: 1 µm at nose
Mega Micro Perfect Seal Nut (For 6S and 8S Bodies Only)
Max Coolant Pressure 1,000PSI
Through Tools - with PS Ring
Jet Through - without PS Ring
Suitable for eliminating dust and contaminants. The unique design of the Perfect Seal increases sealing performance with higher coolant pressure. Remove the PS Ring to supply coolant to the cutting tool periphery.
Replaceable seal used in Mega Micro Perfect Seal Nut
Spare seal is recommended when coolant leaks due to damage of PS Ring.
