Boneham H134CQ Press Fit Headed Drill Bushing Type H

Product Description

The BONEHAM H134CQ is a Type H press fit headed drill bushing manufactured from steel. It is designed to guide drill bits with precision during repetitive drilling operations in jig and fixture applications. The bushing features a 0.089 inch (wire gauge #43) inside diameter with a tight tolerance of +0.0001 to +0.0004 inches, ensuring consistent hole location and accurate drilling. The headed design provides a positive stop against the jig plate surface, and the press fit installation method secures the bushing permanently in place without the need for a locking mechanism. Machinists, tool and die makers, and precision fabricators use this component in production drilling setups.

This bushing is suited for permanent installation in drill jigs used in metalworking, manufacturing, and fabrication environments. The headed body style seats flush against the jig plate face while the body extends into the jig plate bore. The 1/4 inch length under head accommodates standard jig plate thicknesses. It is not designed to be renewable or interchangeable after installation. Typical applications include high-volume production drilling where consistent hole registration is critical.

Installation Notes

Installation is performed by pressing the bushing into a precision-bored hole in a drill jig plate using an arbor press or similar pressing equipment. Power down all machinery and secure the workpiece before pressing the bushing into the jig. Do not hammer the bushing directly, as this can distort the bore or damage the head. Once pressed into place, this bushing is not intended for removal or replacement.
