Boneham H206ES Press Fit Headed Drill Bushing Type H

Product Description

The BONEHAM H206ES is a Type H press fit headed drill bushing designed to guide drill bits with precision in jig and fixture applications. Manufactured from hardened steel with a Rockwell hardness rating of 60 to 65 HRC, this bushing is pressed directly into a drill jig plate and held in place without a locking mechanism. The inside diameter is 0.154 inches (Number 23 wire gauge equivalent) with a tight tolerance of +0.0001 to +0.0004 inches, ensuring consistent hole location across repeated drilling operations. It is a non-renewable, fixed installation bushing suited for production and tooling environments.

This bushing is used in metalworking, machining, and fabrication shops where accurate hole placement is required. It is appropriate for drill jigs used in medium to high-volume production settings. The headed design allows the bushing to seat flush against the jig plate surface, preventing the bushing from being pushed through during operation. Machinists, tool and die makers, and fixture builders are the primary installers of this component.

Compatibility

Designed as an OEM-style replacement or direct installation component for drill jigs and fixtures requiring a Type H press fit headed bushing with a 0.154 inch inside diameter and 5/16 inch body outside diameter per ANSI specifications.

Installation Notes

Press fit drill bushings are installed by toolmakers or machinists using an arbor press to seat the bushing into a reamed hole in the jig plate. The receiving hole in the jig plate must be reamed to the correct interference fit dimension before installation. Do not hammer the bushing directly without a press plate or driver to avoid damage to the head or bore. Once installed, this bushing is not designed for removal and reuse.
