MEGA CHUCKS are micro-mirror finished on all surfaces to ensure perfect concentricity for high-speed machining. The MEGA CHUCKS are then balanced with a high-precision dynamic balancing machine. Notch-Free MEGA NUT Design Prevents Vibration & Reduces Noise Vibration at high speeds is eliminated with the use of notch-free nuts, which offer superior balance and concentricity. This ideal nut design not only reduces whistling noise and splattering coolant, but also ensures increased strength of the nut itself.
