The Omega BT40 Face Mill Arbor with Through Coolant is engineered to securely hold face milling cutters in BT40 spindle machines while delivering coolant directly to the cutting edge. This through-coolant design supports efficient chip evacuation and consistent cutting performance in demanding milling tasks.

Operating across a wide speed range from 15,000 to 25,000 RPM, it pairs with precision ratings of G2.5/G6.3 to maintain stability and accuracy during high-speed milling. Built-in coolant channels ensure the coolant reaches the cutting edge where it matters most, helping sustain cutting performance and prolong tool life.

• Through-Coolant Channel Design: Built-in coolant channels route coolant directly to the cutting edge, improving chip evacuation and cutting performance.
• High-Speed Stability and Precision: With a speed range of 15,000–25,000 RPM and a precision rating of G2.5/G6.3, it delivers stable, accurate milling during demanding operations.
• BT40 Compatibility with 100 mm Gauge Length (Form AD/B): Designed to securely hold face milling cutters in BT40 spindle machines, featuring a 100 mm gauge length and Form AD/B with integrated through-coolant for reliable operation.

This BT40 face mill arbor enables fast, reliable high-speed milling with direct coolant delivery, helping you achieve consistent results, reduce downtime, and maintain productive workflows across a range of production and workshop environments.
