The Omega BT40 Shrink Fit Chuck with Front Face Coolant is a precision toolholding solution designed for BT40 spindles. It delivers strong, uniform clamping and rigid holding to help you achieve repeatable results in high‑speed milling and drilling. Built for engineers, machinists, and shops that demand dependable performance, this chuck provides consistent grip and reliability under demanding conditions.

Aligned to BT MAS403 (JIS 6339) standards, it utilizes Form AD/B with integrated front coolant channels for efficient heat management during fast cuts. The design features a precise 4.5-degree seating angle and is balanced to G2.5 at 25,000 RPM, ensuring smooth operation at high speeds. It also incorporates a 5 mm interface and a 120 mm length for compatibility with typical BT40 setups.

• Powerful shrink‑fit clamping for maximum rigidity: Delivers uniform, high-strength grip around the tool, reducing runout and improving repeatability in demanding milling and drilling tasks.
• Front-face coolant channels for efficient cooling: Directs coolant to the cutting area to control heat, extend tool life, and maintain precision during high-speed operations.
• BT MAS403 (JIS 6339) compliant and precisely balanced: Ensures compatibility with standard BT40 spindles and minimizes vibration at 25,000 RPM for reliable, steady performance.

With these features working together, you gain faster setup and changeover, tighter gripping stability, and cooler, more consistent results across a range of machining applications. The balanced, standards-compliant design helps reduce downtime, extend tool life, and deliver dependable performance that you can trust in every production run.
