The Omega DV40 Shrink Fit Chuck is a precision tool holder designed for high-speed machining. It’s ideal for engineers, machinists, tradespeople, and serious hobbyists who need dependable tool retention at elevated speeds, specifically with 5 mm shanks and up to 25,000 RPM.

Using a heat-induced shrink-fit process, this chuck expands to release tools for easy insertion and then cools to grip tightly around the shank. The result is a secure, clamped-like hold without external clamps, delivering minimal runout and consistent performance. With a 120 mm overall length, it’s built for stable, versatile setups across a variety of machines and work flows.

• Shrink-fit retention for secure grip: Heat-and-cool expansion creates a tight, repeatable hold on 5 mm tool shanks, reducing runout and improving overall machining accuracy.
• G2.5 balance for smooth high-speed operation: Engineered for stable performance at up to 25,000 RPM, minimizing vibration and delivering clean finishes over long runs.
• Extended reach and rigidity (120 mm length): The longer form provides solid support and flexible setup options without compromising stability during demanding cuts.

This chuck simplifies setup, minimizes downtime, and helps you achieve repeatable, high-quality results across milling, drilling, and finishing tasks. Its reliable retention and balanced performance empower you to work confidently at high speeds, delivering consistent finishes and reduced rework in daily production or precision projects.
