Omega Products BT40 Shrink Fit Chuck - G2.5 - 25,000 RPM - 8mm - 160mm Long

The Omega BT40 Shrink Fit Chuck is a precision toolholding solution designed for high-speed CNC milling. It accommodates 8 mm shanks and features a 160 mm long body, using a heat-activated shrink-fit to securely grip the tool and deliver true concentric rotation up to 25,000 RPM. This setup minimizes runout and deflection, helping you achieve tight tolerances and superior surface finishes even on demanding parts.

Engineered for engineers, machinists, and shop teams, this chuck combines robust construction with reliable performance in production environments. Its balanced, high-precision design supports consistent results and straightforward tool changes, enhancing overall efficiency in busy machining workflows.

• G2.5 precision concentricity at 25,000 RPM: Maintains minimal runout for accurate milling and repeatable, high-quality finishes under demanding cutting speeds.
• Shrink-fit, heat-activated tool grip: Delivers secure, repeatable clamping with excellent vibration damping, reducing chatter and tool deflection.
• Rigid 160 mm long body for 8 mm shanks: Provides stable mounting and balanced rotation, offering extended reach and consistent performance in tall setups and larger workpieces.

This BT40 shrink-fit chuck helps you cut more predictably, finish surfaces cleaner, and extend tool life by delivering precise toolholding, reduced vibration, and reliable performance in high-speed machining. It’s a dependable choice for maintaining workflow efficiency and achieving consistently solid results across a range of demanding applications.
