The Omega BT40 DMC Collet Chuck (DMC08) is a precision tool holder designed for BT40 spindle systems, delivering secure tool seating and reliable performance in high-speed milling. With a 90 mm gauge length, it stays rigid under load and supports up to 25,000 RPM, making it ideal for demanding machining tasks.

Featuring G2.5 precision for minimal runout, and a Double-Margin Collet (DMC) design that enhances gripping force and concentricity, this chuck delivers superior cutting performance and smoother finishes.

• High-speed performance up to 25,000 RPM: Enables faster material removal and efficient machining while maintaining consistent tool control and surface quality.
• Ultra-tight runout with G2.5 precision: Keeps tolerances tight and ensures accurate diameters, straight holes, and a clean, repeatable finish.
• Double-Margin Collet (DMC) for secure grip and concentricity: Provides stronger clamping and improved concentricity, reducing tool deflection and delivering reliable results across demanding jobs.

The BT40 DMC Collet Chuck helps streamline manufacturing workflows by delivering repeatable, accurate results with minimal setup and adjustment. Its robust build and precise seating support consistent tolerances across batches, while the 90 mm gauge length adds rigidity in challenging operations. Suitable for shops, manufacturers, and serious hobbyists, it offers dependable performance under demanding machining conditions and broad compatibility with BT40 tooling.
