The Omega Products BT40 DMC Collet Chuck (DMC10) is a precision tool holder engineered for BT40 spindle systems. It delivers stable, repeatable tool seating for high-speed milling, featuring a maximum speed of 25,000 RPM and a 90mm gauge length to fit a wide range of setups.

Engineers, machinists, shops, and hobbyists will appreciate its reliable grip and superb concentricity. The DMC (Double-Margin Collet) design provides stronger clamping and tighter runout control, translating to improved cutting performance and smoother surface finishes across a variety of materials and applications.

• Up to 25,000 RPM for fast, efficient milling: Enables higher material removal rates and shorter cycle times while maintaining precise tool control and stability.
• Double-Margin Collet (DMC) for secure, stable grip: Distributes clamping pressure evenly to minimize tool slip and enhance concentricity for consistent results.
• G2.5 precision for minimal runout: Delivers tight tolerances and repeatable finishes from part to part, reducing scrap and rework.

With this BT40 DMC Collet Chuck, you gain a dependable, high-performance toolholding solution that supports faster machining, reduces setup and rework, and improves part quality. Its robust design and precise alignment help you maintain consistent results across shifts, boost productivity, and extend tool life by minimizing vibration and wear. Suitable for a wide range of BT40 milling applications—from prototyping to production—the DMC10 is a trusted choice for shops that demand reliability and repeatability.
