Boneham P2012EF Press Fit Headless Drill Bushing

Product Description

The BONEHAM P2012EF is a headless press fit drill bushing used to guide drill bits and cutting tools with precision in jig and fixture applications. Manufactured from steel, this bushing installs without a head flange, seating flush within the jig plate for a clean, low-profile setup. The inside diameter measures 0.1405 inches with a tolerance of +0.0001 to +0.0004 inches, providing consistent tool guidance and accurate hole location. The body outside diameter is 5/16 inches and the overall bushing length is 3/4 inches. It carries Industry Code P and is a permanent, non-renewable bushing intended for fixed installations. Machinists and toolmakers install this bushing in production drilling and reaming operations where tight positional accuracy is required.

This bushing is suited for use in drill jigs, fixture plates, and tooling assemblies in manufacturing and machine shop environments. It is designed for applications where a flush-mounted, headless configuration is preferred to avoid interference with workpiece surfaces or mating components. The P2012EF fits wire gauge size #28 tooling and is appropriate for both light and medium-duty drilling operations in steel jig plates.

Key Features

Compatibility

Designed as an OEM-style press fit headless drill bushing conforming to Industry Code P standards, suitable for use in standard drill jig plates and fixtures requiring a 5/16-inch outside diameter bushing bore.

Installation Notes

Installation is performed by pressing the bushing into a prepared hole in a jig plate using an arbor press or hydraulic press. The receiving bore should be machined to the appropriate interference fit tolerance before installation. Power down all associated machinery before performing jig maintenance or bushing replacement. Once pressed in, this is a permanent, non-renewable bushing and is not intended for field removal and reuse.
