Global Cnc Industries 8601B .500 Tool Holder Bushing Type B

Product Description

The GLOBAL CNC INDUSTRIES 8601B .500 is a Type B rotary tool holder bushing designed to locate and support cutting tools, drill bits, and other rotating tool shanks within tool holders and jig plates. With a 0.500 inch inside diameter and a 0.750 inch outside diameter, this bushing provides a precise bore for guiding 1/2 inch shank tooling. The 1.5 inch length under the head offers sufficient engagement depth for stable tool support in production and maintenance machining applications. Machinists and toolroom technicians install this component in drilling jigs, fixture plates, and rotary tool holders across light to medium manufacturing environments.

This bushing is suited for use in drilling and boring fixtures where accurate tool guidance is required. The Type B head configuration features a 0.190 inch thick flange that seats flush against a counterbored surface, keeping the bushing positively located under drilling loads. Typical applications include production jig drilling setups, CNC fixture plates, and manual drill press operations where repeatable hole location is critical. It is commonly installed by machinists, toolmakers, and CNC setup technicians in job shop and production machining environments.

Installation Notes

Installation is typically performed by a machinist or toolmaker during fixture assembly or tooling changeover. Press or hand-fit the bushing into the counterbored receiver, ensuring the head seats fully and squarely against the fixture surface. Verify bore cleanliness and check for burrs in the receiver before installation. Power down any associated machine spindle and follow applicable shop safety procedures before servicing tool holders or fixture plates.
