Boneham P888NP Press Fit Headless Drill Bushing

Product Description

The BONEHAM P888NP is a press fit headless drill bushing designed to guide drill bits with precision in jig and fixture applications. Machined from steel, this Industry Code P bushing features a 53/64 inch inside diameter and a 1-3/8 inch body outside diameter, with an overall length of 1/2 inch. The headless design allows the bushing to sit flush within a tooling plate or drill jig, making it suitable for applications where a protruding head would interfere with the workpiece or clamping setup. Machinists and toolmakers rely on press fit bushings like this to maintain accurate hole location and protect the jig from drill wear.

This bushing is used in metalworking, fabrication, and production environments where repeatable hole positioning is critical. It presses directly into a prepared receiver hole in a drill jig or fixture plate without the need for a locking collar or liner bushing. The non-renewable design means it is intended for permanent installation. Typical applications include production drilling jigs, assembly fixtures, and custom tooling setups in machine shops and manufacturing facilities.

Key Features

• 53/64 inch inside diameter with a tight tolerance of +0.0002 to +0.0006 inches for accurate drill guidance
• 1-3/8 inch body outside diameter for secure press fit retention in the jig plate
• 1/2 inch overall length suits shallow fixture plates and compact tooling setups
• Headless design sits flush with the jig surface, eliminating protrusion interference
• Steel construction provides durability and resistance to wear from repeated drill passes
• Non-renewable, permanent-installation bushing per Industry Code P classification

Compatibility

Designed as an OEM-style replacement or direct-install press fit headless drill bushing for drill jigs and fixture plates requiring a Type P bushing with 53/64 inch ID and 1-3/8 inch OD.

Installation Notes

Installation is typically performed by a machinist or toolmaker using an arbor press or hydraulic press to drive the bushing into a properly sized receiver hole. The receiver hole should be machined to match the bushing outside diameter tolerance to ensure a secure press fit without damage to the bushing bore. Do not use impact tools, as they can distort the ID and affect drill guidance accuracy. Verify hole alignment in the fixture before pressing the bushing to final seating depth.
