Value Collection SC99166522 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC99166522 is a Type J rotary tool holder bushing designed to locate and support cutting tools in drill jigs, fixtures, and tooling plates. With a 5/16 inch (0.3125 inch) inside diameter and a 1 inch outside diameter, this bushing guides drill bits, reamers, and similar rotary tools with precision. The head thickness measures 0.265 inches, and the length under the head is 1-3/4 inches (1.750 inches). Machinists, toolmakers, and fixture builders install this type of component when repeatable hole location and tool support are required in production or maintenance environments.

This Type J drill bushing is suited for use in jig and fixture applications across machine shops, fabrication facilities, and maintenance operations. The pressed or slip-renewable bushing design accommodates standard tooling setups where accurate tool guidance is critical. The 7/8 inch distance between hole centers and a 7/16 inch dimension at the D measurement point make it compatible with standard Type J bushing configurations used in industrial tooling layouts.

Compatibility

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

Installation Notes

Tool holder bushings are typically installed by machinists or toolmakers using a bushing press or arbor press to achieve the correct interference or slip fit. Always verify bore diameter and surface finish in the fixture plate before installation to avoid damage to the bushing or liner. Ensure the workpiece fixture is properly secured and all rotating equipment is powered down before servicing or replacing bushings in an active production jig.
