Meet the Omega DV40 Shrink Fit Chuck. This high-precision toolholding solution is designed for demanding CNC work, delivering secure, consistent grip on your cutting tools at high speeds. With a 12 mm interface and an overall length of 160 mm, it’s built to fit a wide range of setups while keeping tool runout to a minimum.

Capable of up to 25,000 RPM and featuring a G2.5 balance rating, the DV40 provides stable, smooth operation even under aggressive feeds. The shrink-fit design uses heat-induced expansion to securely grip the tool, then cooling to lock it in place, eliminating the need for external clamping and reducing setup complexity.

• Tight, repeatable tool grip: Shrink-fit technology expands when heated to hold the tool securely, then contracts as it cools to minimize runout and deliver consistent machining results.
• High-speed capability up to 25,000 RPM: Optimized for fast spindle speeds, maintaining balance and precision during demanding milling operations.
• G2.5-balanced for smoother operation: A precision balance rating reduces vibration, supporting cleaner finishes, longer tool life, and reliable repeatability.

Designed to streamline your workflow, the DV40 shrink-fit chuck reduces setup time and boosts accuracy. A secure, tool-on-and-off grip minimizes runout for tighter tolerances and superior surface finishes, even in challenging materials. Built for reliability in busy workshops, its robust construction and precise machining deliver consistent results across long production runs, helping you meet deadlines and maintain quality.
