Jacobs Universal Three Jaws Chuck 6.3mm

Clinical Application

This three-jaw chuck provides secure, concentric retention of round-shank rotary instruments used in surgical procedures. It is intended for holding drill bits, burs and small reamers when performing bone drilling, hole preparation for fixation, burr work in ENT or neurosurgery, and other procedures that require driven rotary tools. The universal three-jaw design simplifies transfer between hand drivers and powered attachments while maintaining grip stability during rotation.

Design & Configuration

The self-centering three-jaw geometry closes uniformly around the tool shank to maximize concentricity and minimize runout—critical for precision drilling and burr work. Uniform jaw engagement reduces slippage and wobble under torque, improving control and protecting both the instrument and surgical site. The universal style accepts a range of round shank tools up to the chuck's stated capacity, enabling quick bit changes and broad procedural versatility.
