Omega Products BT40 Shrink Fit Chucks with Front Face Coolant - G2.5 - 25,000RPM - 25mm - 120mm

Omega BT40 Shrink Fit Chucks with Front Face Coolant are a dependable solution for BT40 spindle setups, combining powerful toolholding with efficient cooling. Designed for high-speed milling, their shrink-fit clamping provides a strong grip and excellent rigidity while the front-face coolant channels remove heat at the source to protect tool life and performance.

Compliant with BT MAS403 (JIS 6339) standards, these chucks feature Form AD/B geometry and integrated front coolant channels that promote effective cooling during demanding operations. With a precise 4.5-degree angle and balance to G2.5 at 25,000 RPM, they deliver reliable performance across a wide range of milling tasks.

• Front Face Coolant Channels: Direct cooling at the cutting edge helps maintain dimensional accuracy, reduce thermal distortion, and extend tool life during high-speed milling.
• Shrink-Fit Clamping with Form AD/B: Uniform, high-strength retention around the tool shank minimizes runout and delivers repeatable, dependable toolholding for consistent results.
• High-Speed Precision (G2.5 @ 25,000 RPM): Engineered balance at 25,000 RPM reduces vibration and supports clean cuts, improved surface finish, and longer tool life in demanding applications.

This combination of robust clamping, integrated cooling, and precision balance helps you streamline setups, reduce downtime, and achieve dependable results across jobs—from roughing to finishing—without compromise on accuracy or reliability.
