Global Cnc Industries 8612J .750 Tool Holder Bushing Type J

Product Description

The GLOBAL CNC INDUSTRIES 8612J .750 is a Type J rotary tool holder bushing designed for use in drill jigs, tooling plates, and precision machining fixtures. It features a 0.750 inch inside diameter and a 1.250 inch outside diameter, with a length under head of 2.125 inches. The head thickness measures 0.265 inches. This bushing provides accurate, repeatable hole guidance for cutting tools in production and job-shop environments. It is installed by machinists and tooling specialists working with CNC machining centers, drill presses, and manual milling setups where consistent tool alignment is required.

This Type J bushing is suited for use in fixed liner applications within jig and fixture assemblies. The 0.625 inch hole diameter and 1 inch distance between hole centers make it compatible with standard jig plate configurations. It is commonly used in medium-duty production drilling operations across aerospace, automotive, and general metalworking applications where tooling accuracy and repeatability are critical.

Installation Notes

Installation is typically performed by a machinist or tooling technician. Ensure the receiving liner or jig plate bore is clean and free of burrs before pressing or inserting the bushing. Power down all machine spindles and verify zero energy state before servicing or replacing tooling bushings in an active fixture. Follow applicable shop safety and workholding standards during installation.
