The Omega BT50 ER Collet Chuck is a precision tool holder for BT50 spindle systems, designed to securely clamp ER40 cutting tools for stable, accurate machining. Built for high-speed milling and drilling, it maintains concentricity and repeatable results across a wide range of applications.

• High concentricity and minimal runout: G2.5 and G6.3 precision ratings deliver tight tool alignment, resulting in smoother cuts and improved surface finish with every pass.
• Wide speed range for versatility: 15,000–25,000 RPM support a broad set of tools and materials, reducing the need to switch holders between jobs.
• Robust BT50 interface with 80mm gauge length: Strong, stable mounting and balanced operation on BT50 spindles, with an 80mm gauge length that simplifies setup and improves rigidity.

With the BT50 ER Collet Chuck, you gain repeatable accuracy, improved cutting performance, and faster, more confident setups. The secure ER40 clamping and precise concentricity help you hit tight tolerances, achieve cleaner finishes, and minimize downtime across demanding machining tasks.
