- Extreme rigidity.
- Axial accuracy: Concentricity . 0.0002"
Straight bushings will grip the end mill evenly across the end mill shank.
- This provides a gripping force twenty times greater than a standard tapered collet.
- Flats and end mill shank depressions will not distort the milling chuck bore.
- Tightening torque of 22 ft/lbs is minimal for a tremendous gripping force as compared to a tapered collet chuck.
- The collapse range is 0.0015" below nominal.
- Holders has coolant thru capabilities.
