The Omega ER16 Mini Nut Collet Chuck (DCBT40) is a precision toolholding solution designed for CNC milling and drilling. With dual contact between the face and taper, it delivers secure tool retention and improved runout control, keeping tools precisely aligned even under demanding machining conditions.

Engineered for high-speed performance, this chuck handles spindle speeds up to 25,000 RPM and is meticulously balanced to G2.5. This combination provides stable operation, smoother finishes, and consistent accuracy across long production runs. The 160 mm gauge length ensures compatibility with common tool changers and makes setup straightforward in tight work envelopes.

• Dual-face and taper contact for secure tool holding: The combined face and taper engagement distributes clamping force evenly, minimizes runout, and keeps tools aligned for repeatable results at high speeds.
• High-speed capability with precise G2.5 balance: Designed for up to 25,000 RPM and balanced to G2.5, reducing vibration for cleaner cuts, longer tool life, and dependable performance in busy production schedules.
• Compact ER16 mini nut with 160 mm gauge length: Slim yet rigid design fits tight setups and standard tool changers, delivering reliable repeatability without increasing machine interference.

This combination of secure holding, high-speed stability, and compact, compatible design translates into faster changeovers, reduced downtime, and higher-quality parts. Operators gain consistent runout control, improved surface finish, and longer tool life across a wide range of industrial applications, from precision pocketing to finishing passes.
