Omega BT40 End Mill Holder (S/L20, Form AD) is designed to securely hold cutting tools in BT40 spindles for high‑speed milling. Built for professionals across engineering shops, manufacturing floors, and even serious hobbyists, it delivers precise tool positioning and reliable performance up to 20,000 RPM, with a G2.5 precision class to ensure repeatable results.

• High-speed performance up to 20,000 RPM: Optimized to maintain balance and alignment at top speeds, reducing vibration and chatter so you get clean cuts and longer tool life.
• G2.5 precision for repeatable accuracy: A tight G2.5 tolerance ensures consistent tool seating and runout across cycles, improving cut quality and dimensional stability.
• 20 mm bore and 200 mm gauge length (Form AD): Broad bore supports common shank sizes, while the generous 200 mm gauge length provides reach and rigidity for deeper milling, with Form AD design for secure, repeatable clamping.

With this BT40 End Mill Holder, you gain reliable toolholding that supports high-speed machining, reduces setup and maintenance downtime, and delivers consistent results across a range of milling tasks—from roughing to precision finishing. The robust construction and precision fit help you achieve smoother surfaces, tighter tolerances, and more predictable throughput, enabling you to optimize workflows and boost productivity in your shop.
