Omega Products BT40 Shrink Fit Chucks with Front Face Coolant - G2.5 - 25,000RPM - 20mm - 120mm

Omega BT40 Shrink Fit Chucks with Front Face Coolant are precision toolholding solutions for BT40 spindles, delivering strong clamping and high rigidity for repeatable results in demanding milling and drilling. With integrated front coolant channels, Form AD/B construction, BT MAS403 (JIS 6339) compliance, and a precise 4.5-degree seating angle, they stay cooler and maintain accuracy at high speeds, balanced to G2.5 @ 25,000 RPM.

• Front Face Coolant Channels: Integrated cooling routes keep the tool and workpiece temperatures down during high-speed cutting, reducing thermal distortion and extending tool life for more parts between tool changes.
• Rigid Shrink-Fit BT40 Clamping: Provides non-slip, vibration-free toolholding that improves dimensional accuracy and surface finish, even under heavy cuts and rapid feed rates.
• Industry-Standard Compliance & Precise Balance: Meets BT MAS403 (JIS 6339) with Form AD/B and is balanced to G2.5 at 25,000 RPM for stable, repeatable performance across a wide range of materials and applications.

This chuck helps you streamline your workflow by delivering reliable, repeatable toolholding with minimal setup and tool change downtime. The front-face coolant keeps temperatures in check and supports consistent part quality at high speeds, while the standard-compliant design ensures easy integration with your existing BT tooling. With these features, you can expect longer tool life, fewer rework cycles, and dependable performance from first part to last.
