The Omega BT40 Shrink Fit Chuck is a high-precision tool-holding solution designed for BT40 spindle machines. It supports 5 mm tool shanks and comes in a compact 90 mm length, making it a versatile choice for engineers, buyers, tradespeople, hobbyists, and shops that demand reliable, repeatable results. With a G2.5 precision rating, this chuck delivers exceptional concentricity and minimal runout to keep your cuts clean and accurate at speed.

At the heart of its performance is the shrink-fit design, which uses controlled heat expansion to firmly grip the tool shank. This creates a stable, vibration-damped interface that minimizes deflection and chatter, improving surface finish and extending tool life. Paired with a maximum speed of 25,000 RPM, the BT40 chuck is ready for demanding high-speed machining tasks without compromising accuracy or reliability.

• G2.5 precision concentricity: Ensures tight runout control for consistent, repeatable cuts and superior surface finishes across jobs.
• Shrink-fit heat expansion grip: Provides a secure, vibration-damped hold on 5 mm shanks for stable performance and reduced tool deflection.
• High-speed capability up to 25,000 RPM: Supports demanding milling tasks with reliable tool retention and minimal downtime.

This BT40 shrink-fit chuck helps streamline workflows by delivering predictable performance, reducing setup time, and lowering scrap rates. Its robust design and precise hold make it a dependable choice for both precision work and rugged manufacturing environments, giving you confidence to push your machines to their limits.
