Jacobs 5046 Drill Chuck Sleeve Chuck No. 34

Product Description

The JACOBS 5046 is a replacement drill chuck sleeve designed for use with plain bearing drill chucks. This sleeve provides the outer housing interface that supports chuck operation and maintains alignment during drilling. It is compatible with Chuck No. 34 and carries model number S34. Installation is performed by machinists, maintenance technicians, and tool repair professionals working on portable or stationary drilling equipment. The part ships as a single unit and is suited for shops that need a direct OEM-style replacement sleeve without sourcing a complete chuck assembly.

This sleeve is used in applications where the existing sleeve on a plain bearing drill chuck has worn, cracked, or been damaged. Plain bearing drill chucks are common in drill presses, hand drills, and bench-mounted drilling equipment found in light industrial, machine shop, and maintenance environments. Replacing the sleeve restores proper chuck function and extends the service life of the existing chuck body without requiring a full chuck replacement.
