Jacobs 30617 Drill Chuck Collar Keyless Precision C-100

Product Description

The JACOBS 30617 is a replacement drill chuck collar designed for use with keyless precision drill chucks. The collar is a structural component of the chuck assembly, securing and aligning the chuck sleeve during operation. It is intended for professional tradespeople and machinists who service or rebuild drill chucks rather than replacing the entire assembly. This part is compatible with Chuck Number 100 and is sold as a single unit. Proper fitment is critical - using this collar outside its designated chuck family can result in improper clamping force or chuck failure.

This collar is suited for light industrial, maintenance, and shop environments where keyless precision drill chucks are in regular service. Typical applications include drill press maintenance, portable drill servicing, and precision machining setups where chuck rebuild or collar replacement is required. It is the kind of part kept on hand by tool repair technicians, machine shop maintenance personnel, and tradespeople who prefer to service their own equipment rather than discard worn tooling.
