The Omega BT40 Shrink Fit Chuck with Front Face Coolant is a precision toolholding solution for BT40 spindle systems, offering strong, repeatable clamping at high speeds. It features Form AD/B, integrated front coolant channels, a precise 4.5-degree contact angle, a 16 mm shank and 160 mm overall length, balanced to G2.5 at 25,000 RPM and compliant with BT MAS403 (JIS 6339) standards.

• Strong, repeatable tool grip: Shrink-fit design envelops the tool shank for uniform clamping force that delivers high rigidity and minimal runout, even at 25,000 RPM, improving cut stability and tool life.
• Front-face coolant for efficient cooling: Integrated coolant channels direct coolant to the cutting edge, helping control temperature, reduce thermal growth, and sustain higher feed rates and cleaner finishes.
• BT40 compatibility and precise geometry: Form AD/B body with front coolant and BT MAS403 (JIS 6339) compliance ensure reliable seating across machines, while the 4.5-degree contact angle and balance to G2.5 at 25,000 RPM support consistent performance.

This combination of strong clamping, targeted cooling, and standard-compliant design helps you maintain tight tolerances, boost productivity, and reduce downtime. Expect repeatable results, longer tool life, and a smoother, more confident workflow from setup to finished part.
