Global Cnc Industries 8603J .875 Type J Tool Holder Bushing

Product Description

The GLOBAL CNC INDUSTRIES 8603J .875 is a Type J rotary tool holder bushing designed for use in drill jigs, fixture plates, and tooling setups requiring precise hole alignment and repeatable positioning. With an inside diameter of 0.875 inches and an outside diameter of 1.5 inches, this bushing provides a stable, close-tolerance guide for rotating cutting tools including drills, reamers, and counterbores. The length under head measures 2.5 inches, and the head thickness is 0.265 inches. It weighs 0.85 pounds. Machinists and tooling engineers install this component when building or maintaining production fixtures that demand consistent drill guidance across multiple workpieces.

This Type J bushing is suited for industrial machining environments where renewable or fixed drill bushings are used in jig plates. The Type J designation indicates a specific head and body geometry used in standard tooling fixture applications. It is appropriate for both job-shop and production-floor setups where drill wandering must be eliminated and hole location repeatability is required. The 7/8 inch hole diameter and 1-1/8 inch distance between hole centers make it compatible with standard jig bushing plate layouts used in precision drilling operations.

Key Features

• Type J bushing geometry with defined head for positive seating in fixture plates
• Inside diameter of 0.875 inches for guiding 7/8 inch tooling
• Outside diameter of 1.5 inches for standard jig plate press or slip fit installation
• Length under head of 2.5 inches provides extended tool guidance through deeper fixture plates
• Head thickness of 0.265 inches for consistent seating depth
• Hole diameter of 7/8 inch with 1-1/8 inch distance between hole centers

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard Type J drill bushing applications in precision jig and fixture tooling setups.

Installation Notes

Installation is typically performed by a machinist or tooling technician. Ensure the fixture plate is clean and free of burrs before pressing or seating the bushing. Confirm that the receiving bore diameter matches the bushing outside diameter tolerance before installation. Always de-energize and lock out any associated machine before servicing or replacing bushings in active fixtures.
