We balance every Überchuck to G2.5@20,000 rpm to ensure high-speed operation and excellent performance.

Dual seals provide all internal compontents with positive protection from dirt and coolant.

A central thru-coolant feature, high-pressure-rated to 1,400 psi, is standard, with sealed collets available for thru-tool collant delivery.

Forget the costly and potentially dangerous induction heaters, or having to hassle with hydraulic presses- you can change or adjust a cutting tool by simply turning a hex key.

Independent testing verifies Überchuck's superior gripping torque that results from our precision worm-gear design and slow collet taper angle (200 Nm/1,770 in-lbs at 1/2" diameter!).

Our own, proprietary surface coating provides easy loosening and fast collet changes. Available in both inch and metric sizes, all Überchuck collets feature a depth-stop screw for precisely adjusting the cutting tool length.

Available in multiple lengths and capacities, and with the flexibility afforded by interchangeable collets, Überchucks can grip tools from 1/8" to 1-1/4" diameter.

How does running at 0.00012" TIR or better at 2.5 x diameter sound? We guarantee it. High accuracy ensures critical part tolerances are met, and because the tool stays on centerline, chip load is evenly distributed, extending tool life.

The Überchuck combines carefully optimized expansion tolerances with exceptional vibration-damping characteristics. The result is more aggressive cutting capabilities, smoother finishes, and up to 60% longer tool life.
