Boneham P8822NU Press Fit Headless Drill Bushing

Product Description

The BONEHAM P8822NU is a headless press fit drill bushing used to guide drill bits and cutting tools with precision in jig and fixture applications. Built from steel, this Industry Code P bushing features a 55/64-inch inside diameter and a 1-3/8-inch outside diameter, with an overall length of 1-3/8 inches. The inside diameter is held to a tight tolerance of +0.0002 to +0.0006 inches, ensuring consistent hole location and tool alignment. It installs directly into a drill jig plate without a head or locking flange, providing a flush, low-profile fit suited to close-clearance setups.

This bushing is intended for use in production and maintenance drilling operations where repeatable hole placement is required. It is commonly installed in hardened drill jig plates for metalworking, fabrication, and machining applications. The headless design makes it appropriate for situations where workpiece clearance or fixture stacking does not allow for a flanged head. Machinists, toolmakers, and fixture builders in industrial and job-shop environments are the primary installers.

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for standard Industry Code P press fit bushing applications in steel drill jig plates.

Installation Notes

Press fit installation is typically performed by a machinist or toolmaker using an arbor press or hydraulic press. Ensure the receiving hole in the jig plate is machined to the correct interference fit tolerance for a Code P bushing before pressing in. Do not hammer the bushing directly without a proper driver to avoid distorting the bore. Once pressed in, the bushing is not designed for removal and reuse.
