Omega DV40 Shrink Fit Chuck is a precision toolholder engineered for high-speed milling and demanding machining tasks. With a DV40 interface, a 20 mm shank, and a total length of 160 mm, it fits a wide range of spindles while delivering exceptional rigidity at speeds up to 25,000 RPM. Its G2.5 balance rating ensures smooth operation even under heavy loads.

Its shrink-fit design uses heat-induced expansion to grip the tool securely, eliminating the need for external clamps and minimizing tool runout. Paired with a G2.5 balance rating, the chuck delivers stable, accurate performance at high speeds, helping you achieve consistent finishes and tighter tolerances.

• Tight, repeatable grip: Uniform clamping forces around the tool shank reduce runout and seating variance, delivering consistent results and longer tool life.
• High-speed stability and precision: Optimized for 25,000 RPM with precise balance, minimizing vibration for cleaner cuts, better surface finish, and higher material removal rates.
• Secure heat-shrink retention: No external clamps needed; heat-induced retention creates a robust, durable interface that simplifies tool changes and maintains accuracy over many cycles.

By delivering precise, repeatable tool seating at high speeds, the Omega DV40 Shrink Fit Chuck helps you cut more efficiently and with greater confidence. The combination of a secure grip, balanced performance, and durable construction reduces downtime, improves finish quality, and supports reliable results across production runs.
