The BT50 ER Collet Chuck from Omega is a precision tool holder designed for BT50 spindle systems. It uses ER25 collets to securely clamp cutting tools, delivering stable, repeatable performance for a wide range of milling, drilling, and finishing tasks.
With a speed range of 15,000 to 25,000 RPM, it covers a broad set of machining operations. The chuck is rated with G2.5 and G6.3 precision, indicating excellent tool concentricity and minimal runout, which translates into consistent cuts and improved surface finish. The 80 mm gauge length provides solid engagement and rigidity to keep tools aligned throughout the cut.
- ER25 compatibility within BT50 spindles: Securely clamps ER25 tools for stable, repeatable machining with dependable tool grip and consistent results.
- High-precision concentricity: G2.5 and G6.3 ratings deliver minimal runout, contributing to smoother cuts, better surface finish, and reduced chatter across operations.
- Wide speed range and solid engagement: 15,000–25,000 RPM supports a broad set of applications, and an 80 mm gauge length provides stable tool positioning for reliable performance.
This combination of secure clamping, precise concentricity, and versatile speed range helps you streamline workflows, reduce rework, and achieve reliable, repeatable results on BT50 spindle systems.
