Boneham P208EC Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P208EC is a headless press fit drill bushing designed to guide drill bits and other cutting tools with precision during machining and fabrication operations. Built to industry code P, this bushing features a 0.136 inch inside diameter, a 5/16 inch body outside diameter, and a 1/2 inch overall length. Constructed from steel, it is intended for permanent installation in drill jigs and fixtures where a low-profile, flush-mount design is required. The tight inside diameter tolerance of +0.0001 to +0.0004 inches ensures repeatable hole location accuracy across production runs.

This bushing is suited for use in drill jig applications across metalworking, tooling, and general manufacturing environments. The headless design allows the bushing to sit flush with the jig plate surface, making it well-suited for setups where a protruding head would interfere with workpiece clearance or tooling travel. It is typically installed by machinists, toolmakers, and fixture builders working in job shop or production settings.

Installation Notes

Press fit bushings are installed by machinists or toolmakers using an arbor press or similar controlled force method to avoid bushing damage or jig plate distortion. The jig plate bore should be finish-reamed to the specified press fit tolerance before installation. Once pressed in, these bushings are not intended for removal or reuse. Verify bushing seating is flush and square to the plate surface before putting the fixture into service.
