Description
The Omega HSK63A Slim Shrink Fit Chuck is built for high-speed milling, delivering minimal runout and strong, even clamping for intricate features. Its slim profile improves accessibility in tight pockets and complex toolpaths, helping you reach areas that standard chucks can’t. With a 12 mm clamping diameter and 160 mm gauge length, the chuck is balanced to G2.5 at 25,000 RPM for stable, precise performance and longer tool life.
- Slim Profile for Tight-Access Machining: The compact design clears space around complex contours, reducing setup time and enabling smoother toolpaths in confined workpieces.
- Shrink-Fit Clamping with Low Runout: Uniform grip along the tool shank minimizes runout, delivering repeatable, high-precision results across demanding milling tasks.
- High-Speed Balance at 25,000 RPM: Balanced to G2.5 at 25,000 RPM to minimize vibration, extend tool life, and improve surface finish on challenging parts.
This chuck helps streamline workflows by delivering stable, accurate toolholding at high speeds, reducing rework and downtime. Its robust construction and optimized balance provide predictable performance across jobs, so you can rely on consistent results from setup to finish.
