Value Collection SC05878996 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05878996 is a Type J rotary tool holder bushing designed for use in drill jigs and precision tooling setups. With an inside diameter of 0.6250 inches and an outside diameter of 1.0000 inches, this bushing provides accurate bore guidance for cutting tools, reamers, and drill bits. The length under head measures 1.7500 inches, and the head thickness is 0.2650 inches. Machining professionals and tool-room technicians install this bushing into jig plates to maintain positional accuracy and reduce tool wander during repetitive drilling and reaming operations.

Type J tool holder bushings are commonly used in production machining environments where jig-based drilling fixtures require a headless or headed liner bushing with precise dimensional tolerances. This bushing fits standard jig plate bores and is suited for use on manual drill presses, CNC machining centers, and dedicated drill jig fixtures found in manufacturing and fabrication shops. The 7/8-inch distance between hole centers and 7/16-inch D-in measurement support standard fixture layouts.

Installation Notes

Tool holder bushings of this type are typically installed and serviced by machining professionals and tool-room technicians. Before installation, ensure the jig plate bore is clean, free of burrs, and dimensionally within tolerance to accept the bushing without excessive force or clearance. Press-fitting equipment or an arbor press may be required depending on the interference fit of the application. Follow applicable shop standards and fixture design guidelines when integrating this bushing into a jig assembly.
