Our BT40 Shrink Fit Chuck with Front Face Coolant is engineered for high‑speed machining where precision, reliability, and efficiency matter most. Designed to handle demanding milling tasks, it delivers strong, repeatable tool holding and rigid performance while staying compliant with BT MAS403 (JIS 6339) standards. The Form AD/B interface ensures a stable, consistent fit with BT40 tooling for smooth operation across jobs.

• Front Face Coolant Shrink Fit Design: Integrated coolant channels in the front face actively cool and lubricate the cutting zone, helping maintain accuracy, extend tool life, and reduce heat-related wear during fast, heavy-cutting operations.
• BT40 Standards Compliance with Form AD/B: Built to exact BT MAS403 (JIS 6339) specifications and Form AD/B geometry, ensuring reliable tool seating, quick changes, and consistent clamping across a busy shop floor.
• High‑Speed Precision and Balance: Precisely engineered with a 4.5° engagement and balanced to G2.5 at 25,000 RPM, delivering smooth, chatter‑free performance for repeatable finishes even at high spindle speeds.

This chuck helps streamline workflows by delivering secure tool retention, efficient cooling, and dependable performance under continuous production. It supports tighter tolerances, reduces non-productive downtime, and provides the confidence to push cutting speeds while maintaining consistent results across jobs.
