Omega Products BT40 End Mill Holder With Coolant Channels - G2.5 - 25,000RPM - 25mm Bore Size - 90mm Gauge Length

Omega BT40 End Mill Holder with Coolant Channels is a purpose-built toolholder for BT40 spindles designed for high-speed milling. It securely clamps end mills while its integrated coolant channels actively manage heat and chip evacuation, helping you keep cutting performance consistent even in demanding operations.

Designed for demanding shops, it combines a 25 mm bore size with a 90 mm gauge length to deliver rigid, accurate alignment at speeds up to 25,000 RPM. The precision rating of G2.5 ensures tight runout and repeatable tool positioning, so every cut meets your quality standards.

• Coolant-Through Design: Direct coolant delivery to the cutting edge reduces heat buildup, improves chip evacuation, and extends tool life for longer intervals between changes.
• High-Speed Precision: Optimized for up to 25,000 RPM with G2.5 precision, delivering repeatable, accurate tool seating and consistent cuts in demanding materials.
• Rigid Bore & Gauge Length: 25 mm bore and 90 mm gauge length provide stable tool mounting and balanced performance, helping reduce vibration and improve surface finish.

This BT40 holder helps you maintain cooler tooling, extend tool life, and achieve consistent surface quality across parts and shifts. The integrated coolant channels support faster chip evacuation and heat dissipation, while the solid bore and gauge geometry deliver reliable positioning for higher productivity without sacrificing accuracy.
