Needle bearing container holds 140% more needle bearings than the traditional design, providing powerful and distortion-free gripping power during heavy duty milling. The internal spiral slot together with the thick wall of the chuck body provides strong torque and rigidity, eliminates distortion in heavy milling, and achieves smooth milling work without vibration or slipping of the end mill.
Clamping force is evenly distributed along the entire tool shank to improve rigidity and surface finish
The internal directional slot also functions as a tunnel for high pressure coolant aimed toward the periphery of the cutting tool
The thick wall around the collet nut provides immense gripping strength by collapsing the taper tightly against the mill chuck body
Runout accuracy is witin 5 micron (0.0002") at 3xD location using a 32mm testing round shank
