Description
The Omega DV40 Shrink Fit Chuck is a high-speed toolholding solution designed for CNC milling and precision machining. Built to securely hold 6mm tooling with a tight, slip-free grip, it supports demanding operations at speeds up to 25,000 RPM. Its shrink-fit design eliminates the need for external clamping hardware, delivering stable performance and minimizing tool runout for consistent results.
With a G2.5 balance rating, this chuck delivers exceptional stability at high speeds, reducing vibration and helping you achieve better surface finishes and longer tool life. The heat-induced expansion and subsequent cooling create a secure grip on the tool, ensuring reliable retention throughout tough milling sessions. Note: the product’s 200mm long body and 6mm tooling compatibility are part of its core design, optimized for reach and rigidity in compact setups.
- Secure shrink-fit retention: Heat-induced expansion and cooling create a tight, slip-free grip on 6mm tooling, eliminating the need for additional clamping hardware and reducing tool runout for accurate cuts at up to 25,000 RPM.
- High-speed balance for precision: G2.5 balance rating ensures smooth operation with minimal vibration, improving surface finish and extending tool life during fast, demanding machining.
- Long-reach, rigid construction: A 200mm body length plus 6mm tooling compatibility delivers extended reach with consistent rigidity, supporting reliable performance in challenging setups.
This chuck helps you streamline workflows by delivering secure tool retention, stable high-speed performance, and durable construction you can rely on day after day. Achieve repeatable results, reduce downtime caused by tool slippage, and maintain high-quality finishes across a range of precision milling applications.
