Boneham H105BP Press Fit Headed Drill Bushing Steel

Product Description

The BONEHAM H105BP is a Type H press fit headed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Machined from steel, this bushing features an inside diameter of 0.0595 inches (Wire Size 53) and a body outside diameter of 5/32 inches, with a length under the head of 5/16 inches. The head outside diameter measures 1/4 inch and the head height is 3/32 inches. Press fit installation locks the bushing permanently in the jig plate without the need for locking mechanisms. Machinists, toolmakers, and fixture builders install this component in production drilling operations where repeatable hole location is required.

The H105BP is suited for use in drill jigs requiring a permanent, non-renewable bushing solution. The headed design seats flush against the jig plate surface, providing a positive stop during installation and resisting axial pullout under drilling loads. This bushing is appropriate for light-to-medium production drilling, reaming, and similar guided-tool operations in metalworking, fabrication, and machine shop environments where tight positional tolerances must be maintained consistently across multiple workpieces.

Key Features

• Press fit installation method for permanent, fixed placement in jig plates
• Inside diameter tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• Steel construction for durability in production drilling environments
• Headed design provides a positive axial stop and resists pullout
• Non-renewable (fixed) bushing — no lock ring required
• Wire Size 53 ID accommodates standard drill wire gauge tooling

Compatibility

Designed as an OEM-style replacement or direct fitment for Type H press fit headed drill bushing applications in standard drill jig plates with a 5/32 inch diameter bushing bore.

Installation Notes

Installation is performed by machinists or toolmakers using an arbor press to drive the bushing into a precision-reamed hole in the jig plate. The jig plate bore must be machined to the appropriate press fit tolerance to ensure proper retention. Never hammer the bushing in without alignment guidance, as this can damage the ID or distort the bushing body. Verify that the bushing is fully seated with the head flush against the plate surface before placing the fixture into service.
