Omega BT40 Face Mill Arbor with Through Coolant securely holds face milling cutters in BT40 spindle machines, while delivering coolant directly to the cutting edge for efficient chip evacuation and consistent cutting performance.

Designed for high-speed machining, it supports operation from 15,000 to 25,000 RPM and provides stable, precise results at a 200 mm gauge length (Form AD/B). The built-in through-coolant channels ensure coolant reaches the cutting edge where it’s most effective.

• Secure, high-speed toolholding: Delivers rock-solid stability in BT40 spindles, minimizing chatter and delivering consistent surface finishes even at up to 25,000 RPM.
• Integrated through-coolant delivery: Built-in coolant channels route coolant directly to the cutting edge, improving chip evacuation, reducing heat buildup, and extending tool life.
• Precise, repeatable alignment (Form AD/B, 200 mm gauge): 200 mm gauge length with Form AD/B and a precision rating of G2.5/G6.3 gives reliable runout and repeatable cuts across jobs.

This arbor helps you speed setup, boost productivity, and achieve better results with every pass. The secure clamping and tight runout prevent vibration, while through-coolant keeps temperatures in check for longer tool life and cleaner, more accurate finishes. With BT40 compatibility, a 200 mm gauge length, and Form AD/B, it fits a wide range of spindle configurations, enabling smoother workflows and fewer tool changes on demanding milling operations.
