Precision ground and balanced
For high speed machining
MEGA CHUCKs are micro mirror ground finished on all surfaces to assure perfect concentricity for high speed machining. The drive keyway is machined after heat treatment. The MEGA CHUCKs are then balanced with a high precision dynamic balancing machine.

Notch-free design mega nut prevents
Vibration and reduces noise
Vibration at high speeds is eliminated with the use of notch free designed nuts, which offer superior balance and concentricity.


Slim design avoids interference. Ideal for small mold making combining high speed and high precision capability.

100% inspection to guarantee accuracy.
Material, production, heat treatment... everything is selected for precision.

Gripping force is an important element for endmilling with a collet chuck. The long gripping length of the collet in the MEGA E series provides a powerful gripping force.
The shallower taper of the collet improves concentricity in order to achieve better surface finishes and longer cutting tool life.


Two types are individually designed for the most effective coolant supply.
