Boneham P8822NP Headless Drill Bushing 53/64 in Id Steel

Product Description

The BONEHAM P8822NP is a press fit headless drill bushing classified under industry code P, designed to guide drill bits and cutting tools with precision in jig and fixture applications. Machined from steel, this bushing features an inside diameter of 53/64 inches with a tight tolerance of +0.0002 to +0.0006 inches, ensuring accurate tool guidance and repeatable hole placement. The outside diameter measures 1-3/8 inches and the overall length is also 1-3/8 inches. The headless design sits flush with the jig plate surface, making it suitable where a protruding head would interfere with workpiece clamping or part seating. Machinists, toolmakers, and precision fabricators are the primary installers of this component.

This bushing is used in drill jigs, fixture plates, and production tooling setups where consistent hole location is required across repeated operations. The press fit installation method means the bushing is driven directly into a prepared reamed hole in the jig body without additional fasteners or locking hardware. It is not renewable, meaning it is intended as a permanent installation within the jig plate. Applications span general metalworking, manufacturing, and precision machining environments in both job shop and production settings.

Compatibility

Designed as an OEM-style press fit headless drill bushing for use in steel or cast jig plates requiring a P-classification bushing with a 53/64 inch inside diameter and 1-3/8 inch outside diameter.

Installation Notes

Installation is performed by toolmakers or machinists using a press or arbor press to drive the bushing into a precision-reamed hole in the jig plate. The receiving hole must be reamed to the correct interference fit tolerance to ensure the bushing seats securely without distortion. Do not hammer the bushing in without a driver or press sleeve, as this can damage the ID tolerance. Verify inside diameter clearance for the intended drill or tool shank before pressing the bushing into the fixture.
