The BT40 Slim Shrink Fit Chuck from Omega is a compact, high‑precision tool holder designed for BT40 spindles. Its slim profile improves accessibility in tight work envelopes and reduces tool interference while machining, helping you work more efficiently without compromising grip or stability.

Engineered to BT MAS403 (JIS 6339) standards, it delivers strong clamping force and rigidity at high speeds, with a 3‑degree taper and Form AD/B for stable, balanced performance up to 25,000 RPM.

• Compact, slim design for easy access: Provides better reach and clearance in crowded setups while maintaining a secure tool grip, improving setup efficiency and reducing interference during high‑speed milling.
• BT MAS403 (JIS 6339) compliant with 14 mm clamping: Standards‑based construction ensures consistent clamping strength and reliability, supporting repeatable results with standard 14 mm tooling.
• High‑speed balance to G2.5 @ 25,000 RPM: Precision balance minimizes vibration for smoother operation, longer tool life, and more consistent finishes on demanding materials.

Together, these features enable faster, more reliable tool changes and tighter tolerances in high‑speed machining. The shrink‑fit mechanism provides a rigid grip that translates to repeatable performance, reduced rework, and improved productivity across a range of small‑diameter tooling tasks. For shops seeking dependable accuracy and smooth finishes at speed, this BT40 Slim Shrink Fit Chuck offers consistent, long‑term performance aligned with industry standards.
