Boneham P888NZ Press Fit Headless Drill Bushing

Product Description

The BONEHAM P888NZ is a press fit headless drill bushing manufactured to Industry Code P standards. It is used to guide drill bits and boring tools with precision in jig and fixture applications. The bushing features a 57/64-inch inside diameter and a 1-3/8-inch body outside diameter, with an overall length of 1/2 inch. Constructed from steel, it is pressed directly into a jig plate without a head flange, keeping the top surface flush. Inside diameter tolerance is held to +0.0002 to +0.0006 inches for repeatable hole location accuracy. Machinists, tool and die makers, and precision fabricators install this type of bushing.

This bushing is suited for production drilling, reaming, and boring setups where a headless profile is required to maintain a flat jig surface. The press fit installation method locks the bushing securely in the plate without fasteners. It is appropriate for medium to heavy-duty jig plate applications in both job shop and production environments. The steel construction provides the wear resistance needed for repeated tool passes in metalworking and manufacturing operations.

Key Features

• Industry Code P headless press fit bushing for flush jig plate mounting
• 57/64-inch inside diameter with a tight tolerance of +0.0002 to +0.0006 inches
• 1-3/8-inch body outside diameter for a secure interference fit in the plate bore
• 1/2-inch overall length suits shallow jig plate applications
• Steel construction provides hardness and wear resistance for repeated drill passes
• Non-renewable design — pressed permanently into the jig plate

Compatibility

Designed as a standard Industry Code P press fit headless drill bushing for use in jig plates and fixtures requiring a 57/64-inch bore guide and a 1-3/8-inch OD seating hole.

Installation Notes

Installation is performed by machinists or tool and die makers using an arbor press or hydraulic press to drive the bushing into a precision-bored plate hole sized for an interference fit. Power to any associated machine must be off and the workpiece secured before pressing the bushing into place. Do not strike the bushing directly with a hammer, as this can damage the bore and affect inside diameter tolerance. Once pressed in, this bushing is not designed for removal and reuse.
