Boneham H3212FX Press Fit Headed Drill Bushing Type H

Product Description

The BONEHAM H3212FX is a Type H press fit headed drill bushing machined from steel for use in jig and fixture applications where precise hole location is required. With an inside diameter of 0.1935 inches (wire gauge 10) and a body outside diameter of 0.5 inches, this bushing provides accurate drill guidance and repeatable positioning across production runs. The headed design seats flush against the jig plate, resisting axial pull-through during drilling. It is a permanent, non-renewable bushing intended for fixed installations where the drill size does not change between operations.

This bushing is suited for use in drill jigs, fixture plates, and tooling setups in metalworking, fabrication, and machining environments. It is installed by press fitting directly into a prepared hole in the jig body, eliminating the need for locking rings or additional retention hardware. Machinists, toolmakers, and fixture builders working in job shops, production facilities, and maintenance departments use this type of bushing to maintain consistent hole location tolerances across repeated drilling cycles.

Key Features

• Press fit installation — no locking hardware required, permanent seating in jig plate
• Headed design prevents axial pull-through during drilling operations
• 0.1935 inch ID (wire gauge 10) with tight tolerance of +0.0001 to +0.0004 inches for accurate drill guidance
• Steel construction provides durability and wear resistance in production tooling
• Non-renewable design for fixed, single-drill-size jig applications
• Head outside diameter of 0.609 inches and head height of 0.219 inches for positive seating

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jigs and fixture plates requiring a Type H press fit headed bushing with a 0.1935 inch inside diameter and 0.5 inch body outside diameter.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush into a precision-reamed hole in the jig plate. The receiving hole must be machined to the appropriate interference fit tolerance before pressing to avoid bushing damage or misalignment. Because this is a permanent, non-renewable bushing, it should not be removed and reinstalled once pressed into place. Consult applicable tooling standards and fixture design guidelines for recommended press fit hole tolerances.
