Global Cnc Industries 8602J .750 Tool Holder Bushing Type J

Product Description

The GLOBAL CNC INDUSTRIES 8602J .750 is a Type J rotary tool holder bushing designed for use in drill jigs, fixtures, and machine tool setups. It features a 0.750 inch inside diameter and a 1.000 inch outside diameter, with a length under head of 1.750 inches and a head thickness of 0.265 inches. The bushing guides cutting tools such as drills, reamers, and boring bars with precision, maintaining accurate hole location and reducing tool deflection. Weighing 0.21 pounds, it is a compact, solid component suited for production machining environments where repeatable accuracy is required.

This bushing is intended for use in rotating tool applications on drill presses, CNC machining centers, and manual jig setups. The Type J configuration is a standard style commonly specified in machine shop and tooling applications where a headed bushing with defined mounting geometry is required. Machinists, toolmakers, and fixture builders working in both job shop and production settings will find this bushing applicable to a wide range of jig and fixture builds. The 0.625 inch hole diameter and 0.875 inch distance between hole centers accommodate standard mounting hardware for secure installation.

Compatibility

Designed as a standard Type J rotary tool holder bushing for use in drill jig and fixture assemblies requiring a 0.750 inch inside diameter guided bushing.

Installation Notes

Installation is typically performed by machinists or toolmakers during jig and fixture assembly or maintenance. Ensure the mating liner or jig plate bore is clean and dimensionally correct before pressing or setting the bushing in place. Secure the bushing using the appropriate fastener through the 0.625 inch mounting hole, and verify tool clearance before running the machine. Never force the bushing into an undersized bore, as this may compromise concentricity and tool guidance accuracy.
