The Omega DV40 Shrink Fit Chuck is a high-performance toolholder engineered for demanding high-speed milling and drilling. With a maximum operating speed of 25,000 RPM and a G2.5 balance rating, it delivers stable, precise performance even in challenging machining scenarios. The shrink-fit design provides a tight grip on the cutting tool, helping to minimize runout and improve overall machining quality.

Designed for 16 mm tooling and a 200 mm overall length, this chuck uses heat-induced expansion and subsequent cooling to securely hold the tool. This eliminates the need for additional clamping hardware, reducing setup time and potential alignment errors while delivering reliable, repeatable results.

• High‑speed stability up to 25,000 RPM: Maintains precise runout control for consistent cuts and clean finishes across demanding machining operations.
• Shrink‑fit clamping—no extra hardware: Heat-expanded, then cooled to lock the tool in place, delivering a secure grip with quicker, clamp-free setups and less tool movement.
• G2.5 balanced for smooth operation: Reduced vibration at high speeds to protect tool life and improve surface finish and dimensional accuracy.

This combination of speed capability, secure shrink-fit holding, and precise balance supports faster cycle times, tighter tolerances, and dependable performance across a wide range of tooling and applications. The DV40 is designed to be a reliable, long‑lasting part of your high‑speed machining toolkit, helping you achieve consistent results with fewer adjustments and downtime.
