Value Collection SC05879309 Type C Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05879309 is a Type C rotary tool holder bushing designed for use in drill press and milling machine tooling setups. It features a 5/16-inch inside diameter (0.3125 inches), a 3/4-inch outside diameter (0.7500 inches), and a length under head of 2-1/4 inches (2.2500 inches). The head thickness measures 3/16 inch (0.1875 inches). This bushing provides a precise bore-to-bore fit within a tool holder or jig plate, keeping drill bits, reamers, and similar cutting tools properly guided during operation. Machinists and toolroom technicians install this type of component as part of drill jig assemblies or tooling fixtures.

Type C tool holder bushings are commonly used in production machining environments, machine shops, and toolroom applications where repeatable hole location accuracy is required. The 1-7/8-inch slot length accommodates standard locking configurations typical of Type C press-fit or slip-renewable bushing installations. This bushing suits setups where a guided cutting tool must be held in close tolerance alignment with a workpiece, whether in a bench-mounted drill press or a vertical machining center fixture.

Key Features

• Type C bushing configuration for standard jig and fixture installations
• Inside diameter of 5/16 inch (0.3125 inches) for precise tool guidance
• Outside diameter of 3/4 inch (0.7500 inches) for proper bore fit
• Length under head of 2-1/4 inches (2.2500 inches) suits deeper plate applications
• Slot length of 1-7/8 inches supports standard locking hardware engagement
• Head thickness of 3/16 inch (0.1875 inches) provides positive seating against the jig plate surface

Compatibility

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

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Ensure the receiving bore in the jig plate is clean and sized to the correct tolerance for a Type C bushing fit before pressing or inserting the bushing. Power down and lock out any connected machine before servicing or replacing tooling components. Do not force the bushing into an undersized bore, as this may damage the bushing seat or alter the inside diameter tolerance.
