The Omega BT40 End Mill Holder (S/L25) is a precision tool holder designed for BT40 spindle systems used in high‑speed milling. Capable of handling speeds up to 20,000 RPM, it helps keep cutting tools centered and securely clamped for consistent results even under demanding workloads. With a G2.5 precision rating, you can rely on repeatable tool positioning and stable performance from one job to the next.

• G2.5 precision tolerance: Ensures repeatable tool positioning and minimal runout for reliable, consistent milling results.
• Up to 20,000 RPM high-speed capability: Maintains stability and minimizes vibration during fast milling, delivering smooth finishes.
• BT40 interface with 25 mm bore and 200 mm gauge length: Provides secure tool retention and broad compatibility with standard end mills, while offering stable reach for varied setups.

Designed to keep you productive, this holder delivers consistent, repeatable performance in high‑speed milling. The combination of tight G2.5 tolerances, a robust BT40 interface, and a 25 mm bore with a 200 mm gauge length means tool changes are quick and secure, runout is minimized, and vibration is controlled. This leads to more uniform finishes, cleaner cuts, and fewer reworks—even on demanding jobs.
