Global Cnc Industries 8603J .500 Tool Holder Bushing Type J

Product Description

The GLOBAL CNC INDUSTRIES 8603J .500 is a Type J rotary tool holder bushing designed for use in drill jigs, fixture plates, and precision tooling setups. With a 0.5000 inch inside diameter and a 1.5000 inch outside diameter, this bushing provides accurate tool guidance and repeatable positioning in machined components. The 2.5000 inch length under head gives adequate depth for stable seating in thick fixture applications. Weighing 1.14 pounds, it is machined to close tolerances suitable for production and maintenance shop environments. Licensed machinists and toolroom technicians are the primary installers of this component.

This bushing is used in rotary tool holder fixtures where a Type J configuration is required. It fits applications calling for a 7/8 inch hole diameter in the fixture plate. The 1-1/8 inch distance between hole centers and a D dimension of 11/16 inch allow it to be positioned correctly alongside adjacent bushings or locating features. It is suited for both production machining environments and job shop tooling builds where precise drill or reamer guidance is needed.

Key Features

Compatibility

Designed as an OEM-style replacement or direct-fit component for rotary tool holder fixture setups requiring a Type J bushing with a 0.5000 inch inside diameter and a 1.5000 inch outside diameter.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the fixture plate bore is clean and dimensionally verified to the 7/8 inch hole diameter before pressing or seating the bushing. Power down and lock out any associated machinery before installing or replacing bushings in a live fixture. Do not force the bushing into an undersized bore, as this may alter the inside diameter and compromise tool guidance accuracy.
