Value Collection SC05879184 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05879184 is a Type J rotary tool holder bushing designed to locate and support cutting tools, reamers, and drill bits within tool holder bodies used in machining operations. With a 1 inch inside diameter and a 1-3/4 inch outside diameter, this bushing fits standard jig and fixture setups found in machine shops and production environments. The 3 inch length under head provides substantial tool guidance depth, reducing deflection and improving hole accuracy. Weighing 2.068 pounds, this is a solid, precision-dimensioned component. It is typically installed by machinists or toolroom technicians maintaining drill jigs, boring fixtures, or CNC workholding setups.

This Type J bushing is suited for use in renewable bushing applications where the bushing seats into a liner and can be rotated or replaced without disturbing the fixture body. Common applications include drill jig setups in metal fabrication shops, production boring operations, and precision hole-location fixtures. The 1-1/4 inch distance between hole centers and the 3/4 inch D-In dimension support specific fixture configurations where spacing and fit must meet tight tolerances. This part is appropriate for both prototype and production volume work.

Key Features

• Type J bushing configuration for use in renewable liner-style drill jig fixtures
• 1 inch inside diameter and 1-3/4 inch outside diameter for standard jig fitment
• 3 inch length under head for extended tool guidance and reduced bit deflection
• Head thickness of 0.2950 inches (approximately 3/16 inches) for controlled seating depth
• 1-1/4 inch distance between hole centers supports precise multi-hole fixture layouts
• Solid construction at 2.068 pounds for rigidity in high-cycle drill operations

Compatibility

Designed as an OEM-style replacement or direct fitment for Type J renewable drill bushing applications in standard jig and fixture tool holder bodies with a 1-3/4 inch bore and 1 inch tool clearance.

Installation Notes

Installation is performed by machinists or toolroom technicians. Power down and lock out all machine tools before installing or removing bushings from a fixture body. Type J bushings are press-fit or slip-fit into a liner bushing and should be seated fully before use. Verify inside diameter clearance against the tool shank diameter before installation to confirm proper fit and prevent galling.
