All Überchuck Milling Chucks are guaranteed to run within 0.00012″ TIR or better at 2.5 x diameter. High accuracy is important not only for part quality, but also because it ensures that cutting tools stay on centerline, distributing the chip load evenly and significantly extending tool life.Outstanding Rigidity and Dampening
Carefully optimized expansion tolerances and unique vibration-dampening capabilities provide smoother part finishes and up to a 60% increase in cutting tool life.High-Speed Balanced
Most Überchuck Milling Chucks are dynamically balanced to G2.5@20,000 rpm for high speed operation. (Note: KM & CAPTO models balanced to G6.3@15,000 rpm)Versatilec The Überchuck is available in multiple lengths and capacities to handle wide range of applications. Interchangeable collets add to its flexibility.Wide Gripping Range
Model-14 1/8″ – 9/16″ Model-20 1/8″ – 3/4″ Model-32 3/4″ – 1-1/4″Unique Collets
A proprietary surface coating enables easy loosening and fast collet changes. Collets are available in both inch and metric sizes and include a depth stop screw for precise length adjustment of the cutting tool.Thru-Coolant Ready
