Value Collection SC05879176 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05879176 is a Type J rotary tool holder bushing designed for use in drill jigs and tooling fixtures. It provides a precise guide bore for rotating cutting tools such as drills, reamers, and boring bars. The bushing features a 7/8 inch (0.8750 inch) inside diameter and a 1-3/4 inch (1.7500 inch) outside diameter, with a 3 inch length under the head and a 3/16 inch (0.2950 inch) head thickness. Machinists and tooling specialists install this style of bushing into jig plates or fixture bodies to maintain accurate hole location and support tool guidance during production machining operations.

Type J renewable drill bushings are commonly used in production jig and fixture tooling in both job-shop and manufacturing environments. They are designed to be pressed or fitted into liner bushings already installed in a jig plate, allowing the bushing to be replaced when worn without disturbing the fixture. This part is suited for applications requiring a 7/8 inch bore guide with a 1-1/4 inch distance between hole centers. Installation is handled by machinists and tooling technicians in machine shops and manufacturing facilities.
