Value Collection SC05879283 Tool Holder Bushing Type J

Product Description

The VALUE COLLECTION SC05879283 is a Type J rotary tool holder bushing used in machine tool setups to locate and support cutting tools within a drill jig or tooling plate. With a 1.75-inch inside diameter and a 2.00-inch outside diameter, this bushing provides precise bore alignment during drilling, reaming, or boring operations. The head thickness measures 0.295 inches and the length under the head is 3.50 inches, making it suited for applications requiring a substantial depth of tool guidance. At 2.178 pounds, it is a solid, durable component installed by machinists and toolroom technicians on manual and CNC machine setups.

This Type J tool holder bushing is designed for use in rotary tool holder systems found in industrial machining environments, including production drilling jigs, boring fixtures, and precision tooling plates. The 1.5-inch distance between hole centers and a D-in measurement of 0.75 inches are key dimensional references for fixture alignment and proper seating in standard tooling bodies. It is appropriate for both production shop and toolroom applications where consistent tool positioning is critical.

Compatibility

Designed as an OEM-style replacement or standard component for rotary tool holder systems that accept Type J bushings with a 1.75-inch inside diameter and a 2.00-inch outside diameter.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. The machine spindle and any associated tooling power must be fully locked out and tagged out before handling or replacing bushings in a live fixture. Use appropriate press or hand tools to seat the bushing flush and square within the tooling plate or jig body. Verify inside diameter clearance and head seating before returning the fixture to service.
