Value Collection SC05878954 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05878954 is a Type J rotary tool holder bushing designed for use in drill jigs, tooling fixtures, and precision machining setups. It features a 3/8 inch (0.3750 inch) inside diameter and a 3/4 inch (0.7500 inch) outside diameter, with a 1-1/2 inch length under the head and a 3/16 inch (0.1900 inch) head thickness. The head provides a positive stop against the jig plate for consistent, repeatable positioning. This bushing is a standard fixed-type liner used wherever guided drill bushing systems require a stable, press-fit or slip-fit seat in a tool plate or jig body. Machinists, tool and die makers, and fixture builders handle this component during tooling fabrication and maintenance.

This Type J bushing is suited for industrial machining environments where rotating tool guidance is required. It fits into jig and fixture assemblies that accept standard headless or headed liner bushings. Typical applications include drill jig plates in production machine shops, job shops, and fabrication facilities. The 13/16 inch distance between hole centers spec supports layout planning for closely spaced bushing installations. This part is sold individually and is appropriate for both new fixture builds and replacement of worn or damaged bushings in existing tooling setups.

Key Features

• Type J headed bushing configuration with positive-stop head for consistent seating depth
• Inside diameter of 0.3750 inches for 3/8 inch tool or liner guidance
• Outside diameter of 0.7500 inches for standard jig plate bore fitment
• 1.5000 inch length under head provides adequate tool guidance depth
• Head thickness of 0.1900 inches (3/16 inch) for solid, low-profile clamping surface
• 13/16 inch distance between hole centers for close-tolerance multi-bushing layouts

Compatibility

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

Installation Notes

Installation is typically performed by a machinist or toolmaker during fixture assembly or tooling maintenance. Press-fit bushings require an arbor press and properly sized bore in the jig plate — never drive bushings with a hammer, as this can crack or misalign the bushing. Verify bore diameter and finish before installation to ensure proper fit class. Remove all chips and debris from the bore before seating the bushing.
