Boneham P2012EZ Press Fit Headless Drill Bushing

Product Description

The BONEHAM P2012EZ is a press fit headless drill bushing designed to guide drill bits and cutting tools with precision in jig and fixture applications. Built from steel with a hardness rating of 60 to 65 HRC, this bushing resists wear under repeated drilling cycles. It features a 0.161 inch inside diameter, a 5/16 inch body outside diameter, and a 3/4 inch overall length. The headless design sits flush with the jig plate surface, making it well suited for close-tolerance work where a headed bushing would interfere. Machinists, toolmakers, and manufacturing technicians install this type of bushing in production and prototype environments.

This bushing is used in drill jigs, fixture plates, and tooling setups where consistent hole location is required across multiple workpieces. The press fit installation method locks the bushing into the jig body without fasteners, maintaining alignment under the vibration and load of standard drilling operations. It is a common component in metalworking shops, machine shops, and manufacturing facilities handling repetitive hole-drilling operations on steel, aluminum, and similar materials.

Key Features

• Inside diameter of 0.161 inches with a tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Body outside diameter of 5/16 inches and overall length of 3/4 inches
• Meets ANSI standards; Bushing Industry Code P

Compatibility

Designed as a standard ANSI-compliant press fit headless drill bushing suitable for jig and fixture tooling applications requiring a 5/16 inch bore and 0.161 inch inside diameter guide.

Installation Notes

Press fit bushings are installed by a toolmaker or machinist using an arbor press or similar controlled-force equipment to avoid damaging the bushing bore or the jig plate. The receiving bore in the jig plate must be machined to the correct press fit tolerance before installation. Do not drive the bushing in with a hammer, as this can distort the inside diameter and compromise drill guidance accuracy. Inspect the installed bushing for concentricity before placing the jig into production service.
