World’s Smallest Clamping Intervals

Minimal Thermal Displacement The air turbine drive prevents thermal expansion of the spindle, which is essential for die sinking and high accuracy micro machining.

MEGA MICRO COLLET • Wide coverage for small shanks is available with clamping intervals of ø.004" (ø.1mm) • Compact in size; excellent clamping force for small precision applications
