Its dual-contact interface (face and taper) provides exceptional rigidity, helping to keep tool seating true and runout minimal at speeds up to 25,000 RPM. Engineered for ER40 tooling with a 160 mm gauge length, it delivers consistent seating and repeatable accuracy in demanding applications.
Ideal for engineers, machinists, technicians, and serious hobbyists, this chuck combines Form AD precision with a robust, user-friendly design.

- Precision Balanced to G2.5 at 25,000 RPM: Balanced performance reduces vibration for smoother cuts, better finishes, and consistent results during high-speed machining.
