The Omega BT40 ER Collet Chuck is a precision tool holder for BT40 spindles, engineered to securely clamp ER16 tooling for high-speed milling and finishing tasks. It delivers stable tool holding and tight runout control, enabling reliable performance at up to 25,000 RPM.

• Spindle Compatibility: Designed for BT40 spindle systems, ensuring a smooth, secure fit with compatible machines.
• Collet Type: ER16 interface provides consistent clamping on cutting tools with balanced grip for stability.
• Speed Capability: Optimized for high-speed machining up to 25,000 RPM for clean cuts and efficient material removal.
• Gauge Length: 200 mm gauge length to maintain tool geometry and stable reach during operation.
• Form: Form AD/B interface delivers reliable retention characteristics for BT40 tooling.
• Precision Rating: G2.5 precision rating (with reference to G6.3) indicating exceptional concentricity and minimal runout.
• Tool Retention: Robust clamping mechanism minimizes tool movement, reducing vibration and improving surface finish.

In practice, the BT40 ER Collet Chuck translates high-speed capability and precise clamping into tangible benefits: tighter tolerances, smoother surface finishes, longer tool life, and more consistent part quality across production runs. It’s well-suited for general milling, pocketing, and finishing applications where stability and repeatability matter most, especially when working with ER16 tooling on BT40-equipped machines.
