Description
Omega BT40 End Mill Holder with Coolant Channels from Omega Products is designed for high-speed milling, delivering coolant directly to the cutting edge through integrated channels. This setup reduces heat and improves chip evacuation, helping maintain consistent performance during long, demanding passes.
Engineered for a maximum speed of 25,000 RPM and a precision rating of G2.5, it ensures repeatable tool positioning for reliable cuts and smooth finishes. The integrated coolant channels enable direct delivery of coolant to the cutting edge, dissipating heat and prolonging tool life for higher productivity and better surface quality.
- Integrated coolant channels for direct cooling: Directly delivers coolant to the cutting edge to dissipate heat, improve chip evacuation, and extend tool life for more consistent, high-quality finishes.
- High-speed performance with precise G2.5 tolerance: Maintains accurate tool positioning and stable cutting at up to 25,000 RPM, delivering repeatable results and cleaner surface finishes.
- BT40 compatibility with 40 mm bore and 160 mm gauge length: Provides a secure, versatile hold for standard BT40 tooling with a long reach, reducing setup time and ensuring rigid, vibration-free milling.
With this tool holder, you gain improved cooling, reliable tool seating, and consistent performance that translate into shorter cycle times, less downtime, and better overall part quality. The combination of direct coolant flow, tight positioning, and a robust BT40 interface makes it well-suited for demanding machining environments where surface finish, tool life, and productivity matter.
