Value Collection SC05879143 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05879143 is a Type J rotary tool holder bushing used in drill press and CNC machining setups to locate and guide tooling within a drill jig or fixture. It features a 0.500 inch inside diameter to accept the tool shank and a 1.750 inch outside diameter for secure seating in the jig plate. The length under head measures 3.000 inches, and the head thickness is 0.295 inches. This bushing is a standard replacement or new-installation component for shops running precision hole-location work and is installed by machinists and tooling technicians.

This Type J jig bushing is suited for drill press, turret lathe, and CNC drilling applications where accurate hole location is required. It fits into a prepared jig plate bore and retains the drill or reamer during repeated operations. Typical use is in production machining environments, toolroom builds, and fixture fabrication. The 1.250 inch distance between hole centers supports standard liner configurations used in common jig plate layouts.

Key Features

• Type J bushing profile with headless-style shoulder for flush or recessed jig plate mounting
• Inside diameter of 0.5000 inches for standard half-inch drill or reamer shank
• Outside diameter of 1.7500 inches for consistent bore-to-bushing fit
• 3.000 inch length under head provides substantial tool guidance depth
• 0.295 inch head thickness resists axial thrust during drilling operations
• 1.250 inch distance between hole centers for compatibility with standard liner spacing

Compatibility

Designed as an OEM-style replacement or new-installation jig bushing for drill fixtures and machining setups requiring a Type J bushing with a 0.500 inch bore and 1.750 inch outside diameter.

Installation Notes

Installation is performed by machinists or tooling technicians. Press the bushing into the prepared jig plate bore using an arbor press — do not strike the bushing directly with a hammer. Ensure the bore diameter in the jig plate is machined to the appropriate press-fit or slip-fit tolerance before installation. Verify all tooling and workholding equipment is fully de-energized and secured before performing any fixture modifications or bushing replacements.
