Machine Drill Chuck

Machine drill chuck is a specialized, self-centering clamping device, usually with three jaws, designed to securely hold drill bits, taps, or reamers in rotary machines.

It acts as a critical interface between the machine spindle and tool, using a threaded mechanism to move jaws inward for high-torque, precise centering, with common types including keyed for high security and keyless for rapid changes.
