Value Collection SC05879036 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05879036 is a Type J rotary tool holder bushing used in drill press and machining setups to support and guide cutting tools within a tool holder or jig plate. With a 5/8 inch (0.6250 inch) inside diameter and a 1-1/4 inch (1.2500 inch) outside diameter, this bushing provides a precise bore fit for standard rotating tool shanks. The head thickness measures 3/16 inch (0.2650 inch) and the length under the head is 2-1/8 inch (2.1250 inch). Machining professionals and toolroom technicians install these bushings to maintain accurate tool positioning and reduce lateral movement during drilling or reaming operations.

Type J tool holder bushings are a common component in production drilling fixtures and jig setups found in machine shops, manufacturing facilities, and maintenance toolrooms. This bushing is suited for applications requiring a press-fit or slip-fit installation into a jig plate or tool holder body. It accommodates rotating tool shanks where precise alignment and repeatable positioning are critical. The 2-1/8 inch length under the head provides sufficient engagement depth for stable tool support in medium-thickness workholding fixtures.

Compatibility

Designed as an OEM-style replacement or direct-fit component for Type J rotary tool holder bushing applications in standard drilling jigs and machining fixtures.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Verify bore diameter and tolerance in the jig plate before pressing or sliding the bushing into place. Power down and lock out all machinery before servicing or replacing tool holder bushings. Use appropriate press or arbor tools to seat the bushing without damaging the head or bore surface.
