Omega Products DV40 Shrink Fit Chuck With Front Face Coolant - G2.5 - 25,000RPM - 12mm Clamping Diameter - 160mm Gauge Length

The Omega DV40 Shrink Fit Chuck with Front Face Coolant is a precision toolholding solution built for demanding high-speed machining. Manufactured to DIN 69871 standards, it delivers robust clamping and rigid seating at up to 25,000 RPM, with a compact 12 mm clamping diameter and 160 mm gauge length to fit a wide range of tooling setups. Integrated front coolant channels and a 4.5-degree taper, balanced to G2.5, help maintain accuracy and efficient heat management during heavy cuts.

• Front Face Coolant channels: Integrated coolant channels on the front face route coolant directly to the cutting zone, helping dissipate heat and maintain consistent tolerances at high speed.
• DIN 69871 Form AD/B compatibility and 12 mm clamping diameter: Designed to DIN 69871 standards (Form AD/B) with a 12 mm clamping diameter for secure, repeatable tool seating and easy integration into standard setups.
• High-speed balance and taper: 4.5° shrink-fit taper balanced to G2.5 at 25,000 RPM for stable rotation, reduced vibration, and accurate tool seating during demanding cuts.

With the DV40, you gain a reliable, high-performance chuck that supports faster, more consistent machining. Front-face coolant channels help keep cutting temperatures under control, preserving tool life and improving surface finish. The robust shrink-fit design, paired with DIN 69871 Form AD/B compatibility, ensures quick, repeatable tool changes and stable seating across jobs. In high-speed applications, the G2.5 balance at 25,000 RPM minimizes runout and vibration, helping you achieve tighter tolerances and smoother finishes while reducing downtime.
