Omega BT40 Shrink Fit Chuck with Front Face Coolant is built for BT40 spindle setups that demand maximum rigidity and repeatable toolholding at high speeds. Its shrink-fit design delivers strong clamping force and stable accuracy, while the integrated front-face coolant channels efficiently remove heat at the source, helping maintain cutting performance and extend tool life during long runs. This chuck complies with BT MAS403 (JIS 6339) standards and uses Form AD/B geometry to ensure reliable clamping and compatibility with BT40 tooling. It is balanced to G2.5 at 25,000 RPM for smooth operation and precise results.

• Front-face coolant channels: Directs coolant to the cutting edge for efficient heat removal, helping maintain tool life, reduce thermal growth, and deliver consistent finishes during high-speed machining.
• BT MAS403 (JIS 6339) Form AD/B compliant: Ensures reliable compatibility with BT40 tooling and standardization across setups, reducing tool-change time and ensuring repeatable clamping.
• High-speed balance and precise geometry: Balanced to G2.5 at 25,000 RPM with a 4.5-degree taper, delivering smooth rotation, reduced vibration, and accurate seating for consistent results at top speeds.

With this BT40 shrink-fit chuck, you gain confident toolholding, improved heat management, and consistent results across jobs. The robust build and adherence to industry standards help minimize downtime during tool changes and maximize productive machining time. Its balanced construction and front-face coolant support faster cycle times, better surface finishes, and longer tool life, even on demanding materials and high-speed operations.
