Boneham H5622MM Press Fit Headed Drill Bushing

Product Description

The BONEHAM H5622MM is a Type H press fit headed drill bushing manufactured from steel. It is designed to guide cutting tools with precision during drilling, reaming, or boring operations in jig and fixture setups. The bushing features an inside diameter of 21/32 inches with a tight tolerance of +0.0001 to +0.0005 inches, a body outside diameter of 7/8 inches, and a length under head of 1-3/8 inches. The integral head provides a positive stop against the jig plate surface, ensuring consistent tool entry depth. Machinists, toolmakers, and fixture builders install this component in production and maintenance environments where repeatable hole location accuracy is required.

This bushing is used in drill jig assemblies for metalworking, fabrication, and manufacturing applications. It is pressed directly into a prepared jig plate hole without the use of a locking mechanism, making it a permanent or semi-permanent installation. Typical use cases include production drilling fixtures in job shops, OEM manufacturing lines, and maintenance repair operations where hole location consistency is critical across multiple workpieces.

Key Features

• Press fit installation — no locking ring or set screw required
• Inside diameter of 21/32 inches with +0.0001 to +0.0005 inch tolerance for precise tool guidance
• Body outside diameter of 7/8 inches and length under head of 1-3/8 inches
• Head outside diameter of 1-7/64 inches with a 1/4 inch head height for positive seating against jig plate
• Steel construction for durability in repeated drilling cycles
• Non-renewable design — intended as a fixed installation within the jig plate

Compatibility

Designed as an OEM-style replacement or original-fit component for drill jigs and fixtures requiring a Type H press fit headed bushing with a 21/32 inch inside diameter and 7/8 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 jig plate hole must be machined to the correct interference fit dimension to retain the bushing under operating loads. Do not drive the bushing with an unprotected hammer blow, as this can damage the head or distort the bore. Verify bore diameter and surface finish of the mating hole before pressing to ensure proper retention and alignment.
