Description
The Omega BT40 GSK Collet Chuck (GSK16) is a precision toolholding solution designed for BT40 spindle systems and GSK tooling ecosystems. It delivers a secure grip on cutting tools and reliable performance for repeatable, high-precision milling and drilling across a range of materials.
Designed for high-speed machining, it supports up to 25,000 RPM, with a G2.5 precision rating that minimizes runout and preserves concentricity. The 60mm gauge length (L1) contributes to stable engagement and predictable cutting behavior, helping you maintain accuracy across jobs.
- High-speed compatibility up to 25,000 RPM: Enables fast, productive milling with reliable toolholding and consistent cut quality at higher speeds.
- G2.5 precision for minimal runout: Delivers excellent concentricity, tighter tolerances, and smoother finishes across materials.
- BT40/GSK system compatibility with durable construction: Provides secure grip and reduced vibration, backed by robust materials for long-lasting reliability in demanding shop environments.
Designed to integrate seamlessly with GSK BT40 tooling, this chuck minimizes setup time, reduces tool wear, and supports consistent performance across shifts. Its proven build and precise grip help you achieve repeatable results, improve throughput, and maintain high-quality finishes on every part.
