Omega's Dual Contact DCBT50 ER40 Collet Chuck with a 100 mm gauge length is engineered for high-precision tool holding in CNC mills and other high-speed machines. Designed for engineers, machinists, and serious hobbyists who demand repeatable accuracy, it uses face and taper contact for exceptional stability and is precision-balanced to G2.5 at 25,000 RPM.

• Face and taper contact for stability: This dual-contact design distributes clamping force between the face and taper, reducing runout and improving tool holding for consistent part quality.
• Balanced to G2.5 at 25,000 RPM: Form AD balance delivers smooth, vibration-free operation at high speeds, helping extend tool life and achieve cleaner finishes.
• 100 mm gauge length with standard-nut design: Provides repeatable alignment and straightforward tool changes in common machining setups, reducing setup time and errors.

This combination of stability, high-speed balance, and easy setup helps you achieve repeatable results, reduce rework, and maintain consistent finishes across jobs. The rugged construction and precision balancing are designed for demanding manufacturing environments, while the standard-nut design keeps tool changes quick and reliable, so you can keep your workflow moving and meet tight production deadlines.
