Value Collection SC05879119 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05879119 is a Type J rotary tool holder bushing designed for use in drill jigs and fixture tooling applications. It features an inside diameter of 0.875 inches, an outside diameter of 1.5 inches, and a length under head of 2.5 inches, with a head thickness of 0.265 inches. This style of headless press-fit bushing guides drill bits, reamers, and other rotary cutting tools with precision during machining operations. It is typically installed by machinists, toolmakers, and maintenance technicians working with jig boring and drill fixture setups.

This Type J bushing is suited for use in drill jig plates and tooling fixtures found in production machining, maintenance shops, and fabrication environments. The 7/8 inch bore accommodates standard cutting tool shanks of that diameter, and the 1-1/2 inch outside diameter provides a stable press fit in the receiving jig plate. The 2-1/2 inch length under head gives adequate tool guidance depth for through-hole drilling operations. It ships in a single-piece quantity.

Key Features

• Type J bushing geometry with a flanged head for positive axial location in the jig plate
• Inside diameter of 0.875 inches for precise tool shank guidance
• Outside diameter of 1.5 inches for secure press-fit installation
• Length under head of 2.5 inches provides extended drill guidance
• Head thickness of 0.265 inches for consistent seating against the jig plate surface
• Distance between hole centers of 1-1/8 inches supports standard jig layout spacing

Compatibility

Designed as a standard Type J rotary tool holder bushing for use in drill jig fixtures requiring a 7/8 inch inside diameter and 1-1/2 inch outside diameter press-fit bushing.

Installation Notes

Installation is typically performed by a machinist or toolmaker using an arbor press to seat the bushing flush into the jig plate bore. Ensure the receiving hole is clean, dimensionally correct, and free of burrs before pressing the bushing into place. Do not hammer the bushing directly without a proper driver or press arbor, as this may damage the head or distort the bore. Verify inside diameter clearance with the intended cutting tool shank before final assembly.
