Boneham H1312BP Press Fit Headed Drill Bushing

Product Description

The BONEHAM H1312BP is a Type H press fit headed drill bushing designed to guide cutting tools with precision in jig and fixture applications. It features an inside diameter of 0.0595 inches (Wire Size 53) with a tolerance of +0.0001 to +0.0004 inches, a body outside diameter of 13/64 inches, and a length under head of 3/4 inches. Constructed from steel, this bushing is permanently installed by pressing it directly into a jig plate without the need for a locking mechanism. It is suited for toolroom technicians, machinists, and fixture builders who require repeatable drill guidance in production or low-volume environments.

This bushing is applied in drill jig assemblies where consistent hole location and tool guidance are required. The headed design seats flush against the jig plate surface, providing a positive stop that controls the bushing's depth. The counterbored seat accommodates the head profile. It is used in metalworking, fabrication shops, and manufacturing facilities where fixed, non-renewable bushing installations are appropriate for the application.

Installation Notes

Installation is performed by a machinist or toolroom technician using an arbor press to seat the bushing flush into the jig plate bore. The receiving bore in the jig plate must be machined to the correct press fit tolerance before installation. Because this is a non-renewable bushing, the jig plate bore must be re-machined or the plate replaced if the bushing needs to be changed. Power down all machinery in the work area before installing or removing jig components.
