Description
Introducing the Omega Products Dual Contact DCBT40 ER25 Collet Chuck. Crafted for ER25 tooling, it uses a dual contact (face and taper) engagement to deliver rock-solid stability, precise toolholding, and repeatable results in demanding machining environments. With Form AD design and precision-balanced to G2.5 at 25,000 RPM, this chuck performs smoothly at high speeds, and its 70 mm gauge length supports consistent setup across tooling stacks.
- Dual contact design (face and taper): provides superior stability and concentricity, reducing runout and improving accuracy under load.
- Precision-balanced to G2.5 at 25,000 RPM: minimizes vibration for cleaner finishes, longer tool life, and reliable high-speed performance.
- 70 mm gauge length with Form AD: ensures easy integration with existing setups and repeatable tool seating for consistent results.
This combination of stability, balance, and compatible gauge length helps you maintain tight tolerances, achieve better surface finishes, and keep your machining workflow efficient. Built for demanding engineering environments, it delivers dependable, repeatable toolholding that you can trust for everyday high-speed operations.
