Boneham H1012AX Press Fit Headed Drill Bushing

Product Description

The BONEHAM H1012AX is a Type H press fit headed drill bushing designed to guide drill bits with precision in jig and fixture applications. It features an inside diameter of 0.04 inches (wire size number 60) with a tight tolerance of +0.0001 to +0.0004 inches, ensuring accurate hole placement and repeatable results. The body outside diameter measures 5/32 inches with a head outside diameter of 1/4 inch. Constructed from steel, this bushing is pressed directly into the jig plate and is not renewable. It is typically installed by machinists, tool and die makers, or precision fabricators working with drill jigs.

This bushing is suited for use in drill jig fixtures where a permanent, non-renewable guide is required. The headed design and counterbored seating provide positive axial positioning, keeping the bushing flush and stable during drilling operations. With a length under head of 3/4 inches and a head height of 3/32 inches, it fits standard jig plate thicknesses common in production machining environments. The press fit installation method eliminates the need for locking hardware, making it a straightforward choice for fixed-station drilling setups.

Installation Notes

Installation is performed by machinists or toolmakers using an arbor press to seat the bushing into the jig plate bore. Power down and secure all equipment before pressing the bushing into position. The bushing should be pressed squarely and fully to the head seat to ensure accurate drill guidance. Once installed, this bushing is not designed to be removed and replaced — select the correct size before pressing.
