Description
The Omega Products Dual Contact DCBT40 ER32 Collet Chuck is a high‑precision tool holder designed for CNC milling and drilling applications. Its dual‑contact design—combining face and taper engagement—delivers exceptional stability and minimizes tool runout, so you get repeatable, accurate tool seating even at high speeds.
Built for demanding engineering environments, this chuck uses Form AD balance and is precision‑balanced to G2.5 at 25,000 RPM. With a 70 mm gauge length, it integrates smoothly with standard ER32 tooling systems for fast setup and reliable performance in busy shops.
- Dual‑contact stability: Face and taper engagement distribute clamping forces evenly, reducing runout and improving concentricity for repeatable results at high speeds.
- Form AD balance at 25,000 RPM: Precision balancing minimizes vibration and tool wear, delivering consistent performance and longer tool life in demanding operations.
- 70 mm gauge length with ER32 compatibility: Compact, robust engagement supports quick, repeatable tool seating and broad compatibility with common ER32 tooling systems.
This collet chuck helps you achieve tighter tolerances, reduce downtime, and maintain reliable performance across long machining runs. Its stable gripping, precise balance, and standard ER32 compatibility make it a dependable choice for engineers, operators, and machinists seeking efficient, accurate tool holding.
