Global Cnc Industries 8612B .500 Tool Holder Bushing Type B

Product Description

The GLOBAL CNC INDUSTRIES 8612B .500 is a Type B rotary tool holder bushing designed for use in drill press, milling, and CNC tooling setups where precise tool location and support are required. This bushing features a 0.500 inch inside diameter and a 1.250 inch outside diameter, with a length under head of 2.125 inches and a head thickness of 0.265 inches. It is installed by machinists and CNC technicians to locate and guide cutting tools accurately within tool holder bodies, jig plates, or fixture assemblies. The part weighs 0.66 pounds and is sold individually.

This Type B bushing is suited for precision machining applications in both production and job-shop environments. It fits standard tooling setups where a headed bushing is required to seat flush against a jig plate or fixture surface. Typical applications include drill jigs, reaming operations, and tooling fixtures where repeatable tool positioning is critical. It is appropriate for use in light to medium machining operations on ferrous and non-ferrous workpieces.

Installation Notes

Installation is typically performed by a machinist or CNC tooling technician. The bushing is press-fit or slip-fit into the receiving bore of the jig plate or fixture body depending on the specified tolerance class. Ensure the receiving bore is clean and free of burrs before installation. Verify that the machine or fixture is de-energized and secured before performing any tooling changes.
