Omega Products DV40 Shrink Fit Chuck With Front Face Coolant - G2.5 - 25,000RPM - 3mm Clamping Diameter - 120mm Gauge Length

Engineered for precision milling, the Omega DV40 Shrink Fit Chuck with Front Face Coolant delivers secure toolholding and efficient cooling for high‑speed machining. Built to the DIN 69871 standard and designed for Form AD/B tooling, it provides repeatable, high‑accuracy performance that machinists, engineers, and shop floors can rely on.

Featuring integrated front coolant channels, this chuck pulls heat away from the cutting edge to boost tool life and finish quality—even at demanding speeds. The 4.5‑degree taper, balanced to G2.5 at 25,000 RPM, ensures stable, vibration‑controlled operation, while the 3 mm clamping diameter and 120 mm gauge length offer a compact yet rigid engagement for a wide range of tools and applications.

• High‑Clamping Strength and Rigidity: Shrink‑fit clamping delivers secure tool engagement with minimal runout, improving concentricity and surface finish during high‑speed milling.
• Integrated Front Face Cooling: Direct coolant channels remove heat at the cutting edge, extending tool life and helping maintain precision under heavy cutting loads.
• DIN 69871 Compatibility and High‑Speed Stability: Form AD/B fit with a 4.5° taper, balanced to G2.5 at 25,000 RPM for reliable, vibration‑resistant performance across demanding milling tasks.

Together, these features translate to faster setup, reduced downtime, and more consistent results across a wide range of tools and materials. The DV40’s secure shrink‑fit grip, effective cooling, and precise balance help you achieve better finishes, longer tool life, and improved workflow in both professional shops and precision hobbyist projects.
