The Omega BT50 Face Mill Arbor with Through Coolant is a precision toolholder designed for BT50 spindle machines. It securely holds face milling cutters while delivering coolant directly to the cutting edge to maximize cooling, chip evacuation, and overall performance.

Engineered for high-speed milling, it covers speeds from 15,000 to 25,000 RPM and offers tight accuracy with a G2.5/G6.3 rating. With a 200 mm gauge length and Form AD/B, plus built-in coolant channels, it ensures stable, precise cuts and efficient through-coolant delivery to the cutting edge for improved tool life and surface finish.

• Direct through-coolant delivery: Built-in coolant channels feed coolant directly to the cutting edge, improving chip evacuation and maintaining cooler cutting temperatures for longer tool life.
• High-speed stability and precision: Optimized for up to 25,000 RPM with G2.5/G6.3 tolerances, ensuring repeatable accuracy and reduced runout during demanding milling.
• Robust BT50 toolholding with 200 mm gauge length: Form AD/B compatible, designed for secure mounting in BT50 spindles and easy setup with dependable clamping that minimizes vibration and chatter.

Using this arbor helps keep tooling cooler and more productive. The through-coolant system supports consistent tool life and surface finish, while the solid construction and precise engagement deliver reliable performance across high-speed operations and long production runs.
