Boneham H4022IR Press Fit Headed Drill Bushing

Product Description

The BONEHAM H4022IR is a Type H press fit headed drill bushing designed to guide cutting tools with precision in jig and fixture applications. With an inside diameter of 0.323 inches and a body outside diameter of 5/8 inch, this bushing is pressed directly into a drill jig plate and held in place without a locking mechanism. The head outside diameter measures 51/64 inch with a head height of 7/32 inch. The length under head is 1-3/8 inches. Constructed from steel, it provides the hardness and wear resistance required for repetitive drilling operations in production environments.

This bushing is suited for use in machine shops, tool rooms, and manufacturing facilities where consistent hole location accuracy is required. It is installed in drill jigs used for production drilling, reaming, and boring of metal workpieces. The press fit design makes it appropriate for permanent installations where the bushing is not expected to be replaced during the life of the jig. Machinists, toolmakers, and fixture builders working with standard jig plate materials are the primary installers of this component.

Key Features

• Type H headed press fit design — no locking collar required, permanently retained in jig plate
• Inside diameter of 0.323 inches with a tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• Steel construction provides wear resistance for high-cycle drilling applications
• Head outside diameter of 51/64 inch seats flush or proud against the jig plate surface
• 1-3/8 inch length under head accommodates standard jig plate thicknesses
• Non-renewable design — intended as a permanent fixture component

Compatibility

Designed as an OEM-style permanent press fit drill bushing for use in standard drill jigs and fixtures requiring a headed, non-renewable bushing at the Type H industry designation.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush into the prepared jig plate bore. The jig plate bore must be machined to the appropriate interference fit tolerance before pressing. Power down any associated machinery before servicing or replacing jig components. Do not use impact tools to install, as this can damage the bushing bore or alter dimensional tolerances.
