The Omega BT40 End Mill Holder with Coolant Channels is engineered for high-speed milling, delivering precise tool positioning and efficient cooling in BT40 spindle setups. With a maximum speed of 25,000 RPM and a precision rating of G2.5, this holder helps maintain consistent accuracy even under demanding cutting conditions.

Designed for practical versatility, it features a 12 mm bore size and a 160 mm gauge length, providing secure clamping and stable tool alignment for a wide range of end mills. The integrated coolant channels deliver coolant directly to the cutting edge, cooling the tool, improving chip evacuation, and helping to extend tool life for longer, more productive runs.

• Integrated coolant channels for direct edge cooling: Delivers coolant precisely where it’s needed, reducing heat buildup, extending tool life, and improving chip evacuation for cleaner, more reliable cuts.
• High-speed performance up to 25,000 RPM with G2.5 accuracy: Maintains precise tool positioning at top speeds, yielding consistent finishes and reducing rework or downtime due to runout.
• Rigid 12 mm bore and 160 mm gauge length: Ensures secure, stable toolholding with minimal runout, compatible with a broad range of end mills for flexible, repeatable setups.

In practice, this holder minimizes thermal distortion and tool wear while delivering dependable, repeatable results across long milling runs. The combination of direct coolant delivery, high-speed capability, and solid mechanical design helps you improve surface quality, reduce downtime, and boost overall productivity with confidence.
