Omega Products BT40 Slim Shrink Fit Chuck - G2.5 - 25,000RPM - 3mm Clamping Diameter - 90mm Gauge Length

The Omega BT40 Slim Shrink Fit Chuck is a compact, high-precision toolholding solution designed for BT40 spindles. Its slim profile provides improved accessibility in tight work envelopes, making it ideal for high-speed milling and precision drilling where space is limited. It features a 3 mm clamping diameter and a 90 mm gauge length to fit standard BT40 configurations.

Manufactured to BT MAS403 (JIS 6339) standards, this chuck delivers strong clamping force and rigidity. It uses a 3-degree taper and Form AD/B and is balanced to G2.5 @ 25,000 RPM for stable, vibration-free performance in demanding machining.

• Compact, slim BT40 design: Improves access to tight features and short tooling paths, reducing setup time and enabling more efficient workflows.
• Rigid shrink-fit clamping with 3° taper and Form AD/B: Provides uniform, high-strength grip and enhanced rigidity for reliable tool retention during heavy cuts and high-speed milling.
• G2.5 balance at 25,000 RPM: Delivers smooth rotation with minimal vibration, helping extend tool life and maintain precision at top speeds.

This combination of slim geometry, standards-compliant clamping, and precision balance translates into faster setups, consistent results, and fewer interruptions in busy manufacturing environments. The BT40 Slim Shrink Fit Chuck helps you achieve repeatable part quality across materials while maintaining efficient workflows and long-term reliability.
