The Omega BT40 End Mill Holder with Coolant Channels is a precision tool holder designed for BT40 shanks. It features a 10 mm bore size and a 63 mm gauge length, and it’s built to perform at high speeds up to 25,000 RPM with a G2.5 precision rating. This combination delivers stable, repeatable tool seating for reliable milling results across a range of materials.

The integrated coolant channels route coolant directly to the cutting edge, efficiently cooling the tool, flushing chips away, and reducing thermal wear. This helps extend tool life, maintain consistent cutting performance, and achieve cleaner surface finishes during demanding jobs.

• Direct coolant delivery to the cutting edge: Lets coolant reach the active edge where it’s most needed, cooling the tool, improving chip evacuation, and helping maintain steady cutting temperatures for longer tool life.
• Rigid BT40 fit with 63 mm gauge length: Provides stable, repeatable tool positioning and dependable seating across runs, reducing runout and improving consistency in depth of cut.
• High-speed capability up to 25,000 RPM with G2.5 precision: Maintains precise alignment and reliable performance at demanding speeds, supporting productive milling with tight tolerances.

This holder is designed to support efficient, high-quality milling workflows. By combining coolant-assisted cutting with a robust BT40 interface and precise seating, it helps you push aggressive feeds and maintain surface quality, while lowering downtime due to heat-related wear and tool changes.
