Boneham H1012BP Press Fit Headed Drill Bushing Type H

Product Description

The BONEHAM H1012BP is a Type H press fit headed drill bushing used to guide drill bits and cutting tools with precision in jig and fixture applications. It features an inside diameter of 0.0595 inches, corresponding to a Number 53 wire gauge drill size, with an inside diameter tolerance of +0.0001 to +0.0004 inches for consistent, repeatable hole location. The body outside diameter is 5/32 inches and the length under the head is 3/4 inches. Constructed from steel, this bushing is installed permanently into a drill jig plate and is not designed for renewal or replacement after press fitting. Machinists, tool and die makers, and precision fabricators are the primary installers.

This bushing is suited for use in drill jigs, fixtures, and production tooling where permanent, accurate drill guidance is required. The headed design with a counterbored seat allows the head to sit flush within the jig plate, preventing the bushing from being driven through during drilling operations. It is appropriate for light-duty to medium-duty production environments where close hole tolerances are critical and the bushing will remain fixed for the life of the tooling.

Installation Notes

Press fit bushings are installed by a machinist or tool maker using an arbor press to seat the bushing flush into a counterbored hole in the jig plate. The jig plate hole should be machined to the appropriate interference fit tolerance before installation. Once pressed in, this bushing is not renewable and should not be removed without risk of damaging the jig plate. Always verify hole location and bushing orientation before pressing to final depth.
