Boneham CB00001091 Headless Drill Bushing 15/64 Id 7/16 Od

Product Description

The BONEHAM CB00001091 is a press fit headless drill bushing designed to guide drill bits with precision in jig and fixture applications. Classified under industry code P, this bushing installs permanently into a drill jig plate without a head, providing a flush, low-profile seating surface. It features a 15/64 inch inside diameter with a tight tolerance of plus 0.0001 to plus 0.0004 inches, a 7/16 inch body outside diameter, and a 1 inch overall length. Machined from steel, it is suited for high-repetition drilling operations where accurate hole location and drill guidance are critical. Toolmakers, machinists, and fixture builders are the primary installers.

This bushing is used in metalworking, manufacturing, and machine shop environments where a permanent, non-renewable drill guide is required. The headless design makes it appropriate for applications where the bushing must sit flush with or below the jig plate surface, minimizing clearance issues in tight assemblies. It is not intended for applications requiring bushing removal or replacement after installation. Typical use cases include production drilling jigs in both job shop and high-volume manufacturing settings.

Compatibility

Designed as an OEM-style P-type press fit headless drill bushing for use in standard drill jig plates and fixtures requiring a permanent 15/64 inch ID drill guide.

Installation Notes

Installation is performed by toolmakers or machinists using a bushing press or arbor press to drive the bushing into a precision-reamed hole in the jig plate. The mating hole in the jig plate must be machined to the correct interference fit tolerance to ensure proper retention. Do not hammer the bushing in directly without a press tool, as this can damage the bushing bore or distort the OD. Because this is a non-renewable bushing, removal will typically require the jig plate hole to be reworked or replaced.
