Boneham H2612GF Press Fit Headed Drill Bushing Steel

Product Description

The BONEHAM H2612GF is a Type H press fit headed drill bushing manufactured from steel, designed to guide drill bits with precision in jig and fixture applications. With an inside diameter of 0.204 inches and a body outside diameter of 13/32 inches, this bushing installs permanently into a drill jig plate by press fitting, requiring no locking mechanism. The head design seats flush against the jig surface, providing a positive stop for consistent hole-location accuracy. Machinists, toolmakers, and fixture builders working in production or maintenance environments rely on this style of bushing to maintain repeatable hole placement across high-volume drilling operations.

This bushing is suited for use in drill jigs where a permanent, non-renewable guide is acceptable. The headed style allows it to seat against the top face of the jig plate, making it appropriate for applications where the bushing must resist axial pull-through forces during drilling. The 3/4-inch length under head accommodates moderate plate thicknesses. It is commonly installed by toolroom machinists and fixture fabricators in metalworking, manufacturing, and precision machining environments.

Key Features

• Press fit installation — no retaining screws or locking collars required
• Type H headed design provides a positive seating surface against the jig plate face
• Inside diameter tolerance of +0.0001 to +0.0004 inches for accurate drill guidance
• Steel construction for durability in repetitive drilling applications
• Non-renewable (fixed) bushing — intended as a permanent jig component
• Inside diameter corresponds to wire gauge size No. 6 drill

Compatibility

Designed as an OEM-style press fit headed drill bushing for use in standard drill jig plates where a Type H, 13/32-inch OD permanent bushing is specified.

Installation Notes

Press fit bushings are installed by a toolmaker or machinist using an arbor press or hydraulic press — do not drive with a hammer, as this risks misalignment or bushing damage. The jig plate bore must be machined to the correct interference-fit tolerance before installation. Once pressed in, this bushing is not designed for removal or replacement. Follow applicable shop safety procedures and de-energize any associated machine tooling before servicing jig components.
