Meet the Omega BT40 ER Collet Chuck for BT40 spindles — a precision toolholder designed for ER32 tooling, built to deliver secure clamping and reliable performance in high-speed machining. Ideal for CNC milling and precision drilling, it emphasizes concentricity and stability to help you achieve cleaner finishes and tighter tolerances.

• Interface: BT40 spindle compatibility for secure, repeatable tool mounting
• Collet: ER32 collet system for versatile toolholding of standard ER32 tooling
• Speed range: 15,000–25,000 RPM operation for a wide range of machining tasks
• Precision ratings: G2.5 accuracy and G6.3 concentricity for minimal runout and superior surface finish
• Gauge length: 160 mm gauge length for stable tool overhang and rigidity
• Form: Form AD configuration designed for compact, reliable mounting on BT40 setups
• Construction: Robust, high-precision build tailored for sustained high-speed milling and drilling

In practice, the combination of tight runout and secure clamping translates to better hole quality, smoother finishes, and longer tool life—even at elevated speeds. The 160 mm gauge length enhances rigidity when using longer tooling, while the BT40 interface and Form AD design simplify integration into existing machines and workflows. This ER32 chuck is a reliable choice for professionals seeking repeatable accuracy across pocketing, profiling, and precision drilling applications.
