The Omega BT40 End Mill Holder with Coolant Channels is a precision mounting solution for BT40 spindle systems, designed to keep end mills securely positioned at high speeds. It’s ideal for machine shops, engineers, tradespeople, and hobbyists who demand consistent, repeatable results from their milling operations.

Made for demanding milling tasks, it features integrated coolant channels that deliver coolant directly to the cutting edge, enabling efficient cooling, improved chip evacuation, and longer tool life. With a 16 mm bore, 63 mm gauge length, and a maximum speed rating of 25,000 RPM paired with a G2.5 precision standard, this holder delivers reliable performance across tough applications.

• Integrated coolant channels: Direct cooling at the cutting edge reduces heat buildup, extends tool life, and improves chip evacuation for cleaner, more consistent cuts.
• BT40 interface with 63 mm gauge length: Ensures secure tool seating and repeatable alignment, minimizing runout for reliable performance in every pass.
• High-speed capability up to 25,000 RPM with G2.5 precision: Maintains accurate tool positioning at speed, reducing vibration and boosting surface quality on demanding materials.

This combination helps you maintain cooler tools, extend tool life, and achieve consistent results across production runs. The rigid BT40 interface and precise 63 mm gauge length deliver dependable seating and repeatable results, while the coolant channels support efficient heat management and rapid chip evacuation. Ideal for high-speed milling tasks, it supports improved surface finishes, reduced downtime, and reliable efficiency in both professional shops and serious hobbyist setups.
