Value Collection SC05879259 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05879259 is a Type J rotary tool holder bushing designed for use in drill presses, milling machines, and CNC machining centers where precise tool alignment and support are required. This bushing features a 1 inch inside diameter and a 2 inch outside diameter, with a length under head of 3.5 inches and a head thickness of approximately 0.295 inches. It weighs approximately 2.178 pounds, indicating solid, heavy-duty construction suitable for production and maintenance machining environments. Licensed machinists and toolroom technicians are the primary installers of this component.

This Type J bushing is suited for standard tool holder applications in machining setups where a head-style bushing is required to locate and support rotating tooling. The 1.5 inch distance between hole centers and the 0.75 inch D-in dimension make it compatible with typical jig plate and fixture configurations used in both job shop and production settings. It is appropriate for use in drill jig applications, fixture plates, and tooling assemblies requiring precise bore alignment.

Key Features

• Type J head-style bushing geometry for positive axial location in jig plates and fixtures
• 1 inch inside diameter with a precision bore for accurate tool guidance
• 2 inch outside diameter providing a broad seating surface and stable retention
• 3.5 inch length under head accommodates deeper jig plate thicknesses
• Head thickness of 0.295 inches for positive shoulder stop against the mounting surface
• 1.5 inch distance between hole centers for standard fixture layout compatibility

Compatibility

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

Installation Notes

Installation is typically performed by machinists or toolroom technicians. Press-fit or slip-fit installation into the jig plate bore is standard practice depending on the bushing retention method specified by the fixture design. Ensure the mating bore is clean and within tolerance before installation. Always de-energize and lock out the machine before servicing or replacing tooling components.
