Description
The Omega BT40 Slim Shrink Fit Chuck is a compact, high-precision toolholding solution designed for BT40 spindle systems. It clamps 10 mm tool shanks with a 160 mm gauge length for stability in tight machining envelopes.

- Slim, Accessible Design: Easier tool changes and better chip clearance in tight machine layouts, reducing setup time and increasing overall workflow efficiency.
- Rigid, Consistent Clamping: Shrink-fit gripping delivers uniform clamping around the 10 mm tool shank, minimizing runout and extending tool life for repeatable results.
- High-Speed Balance and Precise Taper: Balanced to G2.5 at 25,000 RPM with a 3-degree taper and Form AD/B geometry for smooth, vibration-free cutting and dependable spindle performance.
Choosing this BT40 Slim Shrink Fit Chuck translates to faster setups, tighter tolerances, and cleaner finishes across a wide range of milling tasks. Its compact form, robust clamping, and proven standards support reliable, long-term performance in high-speed manufacturing environments.
