Boneham H134BT Press Fit Headed Drill Bushing Steel

Product Description

The BONEHAM H134BT is a Type H press fit headed drill bushing manufactured from steel, designed to guide cutting tools with precision during drilling, reaming, and boring operations. With an inside diameter of 0.0635 inches (No. 52 wire gauge) and a body outside diameter of 13/64 inches, this bushing presses directly into a jig plate without the need for locking mechanisms. The headed design provides a positive stop against the jig surface, controlling the bushing's axial position. Inside diameter tolerance is held to +0.0001 to +0.0004 inches, supporting accurate and repeatable hole location across production runs.

This bushing is used in drill jig fixtures for metalworking, fabrication, and machining applications where consistent hole placement is required. It is appropriate for light-duty tooling setups in machine shops, production facilities, and tool-and-die operations. The press fit installation method makes it suitable for permanent or semi-permanent jig tooling where bushing replacement is not a routine requirement. Machinists and toolmakers install this component when building or maintaining drill jigs for small-diameter tooling operations.

Compatibility

Designed as an OEM-style replacement or new-build component for steel drill jig fixtures requiring a Type H press fit headed bushing with a No. 52 wire gauge bore.

Installation Notes

Press fit bushings are typically installed by a machinist or toolmaker using an arbor press to seat the bushing flush and square within the jig plate bore. Ensure the receiving hole in the jig plate meets the required tolerance for a press fit before installation. Once pressed in, this bushing is not designed for routine removal or replacement. Follow applicable shop safety procedures and de-energize any associated machinery before performing jig maintenance or bushing installation.
