Value Collection SC05878962 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05878962 is a Type J rotary tool holder bushing designed for use in drill jigs, tooling fixtures, and machining setups. It features a 0.500 inch inside diameter and a 0.750 inch outside diameter, with a 1.500 inch length under the head and a 3/16 inch (0.190 inch) head thickness. The head flange seats flush against the jig plate to locate and guide cutting tools with repeatable precision. Machinists, toolmakers, and CNC setup technicians install these bushings to maintain drill, reamer, or boring tool alignment during production runs.

This bushing is suited for use in jig and fixture applications in both job-shop and production machining environments. The Type J designation identifies it as a head-style liner bushing, which is pressed or slipped into a jig plate bore and used as a renewable wear insert. The 13/16 inch distance between hole centers is a key layout dimension for multi-spindle fixture design. It is appropriate for light to medium-duty drilling and reaming operations where consistent hole location is required.

Key Features

• Type J head-style bushing for drill jig and fixture applications
• 0.500 inch inside diameter for precise tool guidance
• 0.750 inch outside diameter for standard liner bore fit
• 1.500 inch length under head provides extended tool support
• 3/16 inch head thickness seats securely against jig plate face
• 13/16 inch distance between hole centers for multi-spindle fixture layouts

Compatibility

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

Installation Notes

Tool holder bushings are installed and serviced by machinists and toolmakers working on jig and fixture assemblies. Power down and lock out all machine spindles before removing or installing bushings. Press-fit bushings require proper bore preparation and an arbor press for installation — do not hammer directly on the head flange. Verify inside diameter clearance with the intended cutting tool before final assembly to confirm proper fit.
