Value Collection SC05879028 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05879028 is a Type J rotary tool holder bushing designed for use in drill jigs, fixture plates, and precision tooling setups. It features a 0.5000 inch inside diameter, a 1.2500 inch outside diameter, and a 2.125 inch length under the head. The head thickness measures 0.2650 inches. This bushing guides drill bits, reamers, and other rotating cutting tools to maintain accurate hole positioning and reduce tool deflection during machining operations. Installation and replacement are handled by machinists and toolroom technicians working with jig and fixture tooling systems.

The SC05879028 is suited for use in production machining environments where repeatable hole location is required. It fits into standard Type J bushing liners used in drill jig assemblies across a range of light to medium-duty machining applications. The 1/2 inch bore accommodates commonly used drill and reamer shanks. The distance between hole centers is 1 inch, making it compatible with standard jig plate layouts used in job shop and manufacturing floor settings.

Key Features

Compatibility

Designed as an OEM-style replacement or direct-fit component for Type J rotary tool holder bushing applications in standard drill jig and fixture plate assemblies.

Installation Notes

Type J tool holder bushings are installed and serviced by machinists or toolroom technicians. Ensure the mating liner bore and jig plate are clean and free of burrs before pressing or seating the bushing. Confirm the inside diameter is clear of chips and debris before tool insertion. Follow applicable shop safety procedures and power down any associated machinery before servicing jig fixtures.
