Value Collection SC05879523 Type C Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05879523 is a Type C rotary tool holder bushing used in drill press and CNC tooling setups to locate and support cutting tools within a drill jig or fixture. With an inside diameter of 0.5 inches and an outside diameter of 1.75 inches, it provides a precise bore interface for guiding rotating tools during machining operations. The length under head measures 3.5 inches, with a slot length of 3.125 inches and a head thickness of 0.295 inches. Machinists and tooling specialists install this bushing in production and maintenance environments where repeatable hole location is required.

This bushing is suited for use in drill jigs, fixture plates, and tooling blocks in both light manufacturing and production machining environments. The Type C designation indicates a slip-fixed style with a head, making it appropriate for applications where the bushing is retained by a lock or clamp rather than pressed permanently into the liner. It is commonly installed in setups requiring frequent tool changes or inspection access during a machining cycle.

Key Features

• Type C slip-fixed bushing design allows for tool changes without removing the bushing from the fixture
• Inside diameter of 0.5 inches accommodates standard half-inch drill or boring tool shanks
• Outside diameter of 1.75 inches fits standard liner bushings of the same nominal size
• 3.5 inch length under head provides extended tool guidance for deep-hole applications
• Slot length of 3.125 inches supports positive locking with a lock screw or clamp
• Head thickness of 0.295 inches seats flush or proud against the fixture plate surface

Compatibility

Designed as a standard Type C slip-fixed tool holder bushing for use with compatible liner bushings and drill jig fixtures that accept a 1.75 inch outside diameter slip bushing.

Installation Notes

Installation is performed by tooling technicians or machinists as part of fixture setup. Ensure the liner bushing bore and the mating fixture plate are clean and free of chips before inserting the bushing. A lock screw or clamp should engage the slot to prevent rotation during operation. Do not force the bushing into an undersized liner — verify liner inside diameter matches the bushing outside diameter before assembly.
