The Omega BT40 End Mill Holder with Coolant Channels is a precision toolholder designed for BT40 spindle systems. It securely centers end mills while delivering coolant directly to the cutting edge, promoting efficient cooling and effective chip evacuation during high-speed milling.

With a maximum speed rating of 25,000 RPM and a G2.5 precision class, this holder ensures repeatable tool positioning and reliable performance. Its 6 mm bore and 100 mm gauge length provide versatile compatibility with a wide range of end mills and machining setups, helping you maximize productivity and achieve superior surface finishes.

• Integrated coolant channels for direct cooling: Delivers coolant right to the cutting edge to dissipate heat, improve chip evacuation, and extend tool life for cleaner cuts and longer tool performance between changes.
• High-speed, precise performance up to 25,000 RPM: Maintains stable tool engagement and repeatable accuracy at top speeds, reducing runout and delivering consistent finishes in demanding programs.
• BT40 taper with 6 mm bore and 100 mm gauge length: Provides a robust, widely compatible interface for secure clamping and predictable reach, supporting reliable toolholding in busy milling environments.

By delivering cooling exactly where it's needed and maintaining precise alignment at high speeds, this holder helps you achieve cooler operation, longer tool life, fewer rework passes, and smoother overall workflow — improving throughput without compromising part quality.
