Boneham H265GQ Press Fit Headed Drill Bushing Type H

Product Description

The BONEHAM H265GQ 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 0.221 inches with a tight tolerance of +0.0001 to +0.0004 inches, ensuring accurate and repeatable hole location. The body outside diameter measures 13/32 inches, with a head outside diameter of 1/2 inch and a head height of 5/32 inches. The length under the head is 5/16 inches. Constructed from steel, this bushing is a non-renewable, permanently installed component pressed directly into a drill jig plate. It is installed by toolmakers and fixture builders in machine shop and manufacturing environments.

This bushing is suited for use in drill jigs, fixture plates, and production tooling where a permanent, headed guide bushing is required. The headed design seats flush against the top surface of the jig plate, providing a positive stop and added stability during drilling operations. It is appropriate for light to medium production runs where the bushing does not need to be replaced between operations. The Type H industry code designates a specific head and body dimension standard recognized across the tooling industry, making it straightforward to specify as a drop-in replacement in existing fixture designs.

Compatibility

Designed as an OEM-style replacement or new-installation component for drill jig plates and fixture tooling that specify a Type H press fit headed drill bushing with a 0.221-inch inside diameter and 13/32-inch body outside diameter.

Installation Notes

Installation is performed by toolmakers or machinist technicians using a press or arbor press to seat the bushing into a properly sized hole in the jig plate. The receiving hole should be machined to the bushing manufacturer's recommended press fit tolerance to ensure secure retention without distorting the bore. Do not hammer the bushing in freehand, as this can damage the head or alter inside diameter concentricity. Verify inside diameter clearance with the intended drill or reamer before pressing the bushing into the plate.
