The Omega DV40 Shrink Fit Chuck with G2.5 balance is a high-precision toolholder designed for high-speed milling and drilling. It accepts 10 mm tooling and, at 160 mm long, fits a wide range of machine setups while delivering stable performance at demanding speeds up to 25,000 RPM.

Using a shrink-fit operation, heat expands the chuck to grip the tool, then cooling creates a tight, secure hold. This clamp-free approach minimizes tool runout and helps you achieve consistent results across long cuts and tough materials.

• Tight, repeatable grip: Shrink-fit design delivers a secure hold on 10 mm tools, reducing runout for consistent accuracy across demanding operations.
• High-speed stability: Built for up to 25,000 RPM with G2.5 balance, helping maintain smooth operation and better surface finishes at speed.
• Clamping-free setup: Heat-expanded-to-fit grip eliminates the need for additional clamps, enabling quicker tool changes and simpler setup with reliable retention.

Choosing the DV40 means steadier performance from start to finish. The secure toolholding minimizes vibration and misalignment, supporting tighter tolerances, better finish quality, and reduced downtime with faster, more predictable tool changes. It’s a reliable, straightforward solution for engineers, machinists, and hobbyists seeking consistent results in high-speed applications.
