Omega Products DV40 End Mill Holder is a precision mounting solution for CNC milling that accepts a range of end mill diameters and shank sizes with a 12 mm bore. Designed for engineers, machinists, and hobbyists who require dependable toolholding for both roughing and finishing tasks, this Form AD/B holder combines secure clamping with high-speed stability. With a 100 mm gauge length and a speed range of 15,000 to 25,000 RPM, balanced to G2.5/G6.3, it delivers smooth rotation and repeatable results at demanding speeds.

• Broad milling compatibility: Designed to accommodate a range of end mill diameters and shank sizes, giving you flexible toolholding with a single, reliable mount.
• High-speed, vibration-controlled performance: Optimized for up to 25,000 RPM and balanced to G2.5/G6.3, reducing chatter and delivering cleaner cuts at high speeds.
• Precise clamping for reliable accuracy: Built with a precise construction and dependable clamping mechanism to prevent slippage and maintain consistent results across roughing and finishing operations.

When used as part of your milling setup, the DV40 helps maintain tool alignment under load, reduces chatter, and supports clean, precise cuts across materials. The 12 mm bore provides a secure grip on the end mill while the 100 mm gauge length enhances rigidity for deeper pockets. This combination minimizes downtime from slips or rework and supports consistent performance across jobs, from quick prototyping to production runs.
