Jacobs JCM30347 Drill Chuck Service Kit 18N 3/4 Inch

Product Description

The JACOBS JCM30347 is a drill chuck service kit designed to rebuild and restore 3/4 inch ball bearing drill chucks. It provides the replacement components needed to return a worn or damaged chuck to proper working condition, extending the service life of the tool rather than requiring full chuck replacement. The kit is compatible with the JACOBS 18N chuck model. At 4 pounds, the kit is a practical bench-side solution for machine shops, maintenance technicians, and tool repair professionals who service industrial drilling equipment.

This service kit is intended for use with 3/4 inch ball bearing drill chucks, specifically the JACOBS 18N model. It is suited for industrial and commercial settings where drill chucks are subject to regular use and periodic maintenance. Typical applications include machine tool servicing in manufacturing facilities, toolroom maintenance, and equipment rebuild operations. Technicians who perform in-house tool refurbishment rather than outright replacement will find this kit appropriate for that workflow.

Installation Notes

Chuck service and rebuild work should be performed by a qualified machinist or tool repair technician familiar with rotary tooling components.

Inspect all mating surfaces for wear before installing new service components.
