Omega Products BT40 Shrink Fit Chucks with Front Face Coolant - G2.5 - 25,000RPM - 10mm - 90mm

Omega BT40 Shrink Fit Chuck with Front Face Coolant is a precision toolholding solution designed for BT40 spindles. It holds 10 mm tooling and measures 90 mm in overall length, delivering strong clamping and reliable rigidity for high-speed milling up to 25,000 RPM.

Compliant with BT MAS403 (JIS 6339) standards and Form AD/B, this chuck features integrated front coolant channels that actively cool the cutting edge during demanding cycles. The design helps maintain cutting performance, extend tool life, and reduce thermal distortion when you push speeds and feeds.

• High‑rigidity shrink‑fit clamping: Secure toolholding with strong clamping and stability under heavy milling loads, helping maintain accuracy and consistent results.
• Integrated front face coolant: Direct coolant to the cutting zone for efficient heat removal, lowering temperature rise and improving tool life during high-speed operations.
• Precision balance and BT40 compatibility: Form AD/B with BT MAS403 (JIS 6339) compliance, balanced to G2.5 at 25,000 RPM and a precise 4.5° seating angle for smooth, reliable performance.

This combination of robust clamping, effective cooling, and meticulous balance supports higher productivity, better surface finishes, and longer tool life, making it a dependable choice for manufacturing environments that demand consistency and downtime reduction.
