Boneham H264HD Press Fit Headed Drill Bushing Type H

Product Description

The BONEHAM H264HD is a Type H press fit headed drill bushing designed to guide drill bits with precision in jig and fixture applications. Made from steel, this bushing features an inside diameter of 0.246 inches with a tight tolerance of +0.0001 to +0.0004 inches, ensuring repeatable hole placement in production drilling operations. The headed design provides a positive stop against the jig plate surface, preventing axial movement during use. Machinists, toolmakers, and fixture builders install this bushing by pressing it directly into a prepared hole in a drill jig — no additional locking hardware is required.

This bushing is used in drill jig assemblies for metalworking, manufacturing, and fabrication environments — both job shop and production floor applications. The Type H designation follows the standard drill bushing industry coding system, making it a direct fit for jigs built to that specification. The 1/4-inch length under head and 13/32-inch body outside diameter suit it for moderate jig plate thicknesses where a compact, non-renewable bushing is appropriate.

Compatibility

Designed as an OEM-style replacement or new-installation bushing for drill jigs and fixtures requiring a Type H press fit headed bushing with a 0.246-inch inside diameter and 13/32-inch body outside diameter.

Installation Notes

Installation is performed by toolmakers or machinist-level trades using an arbor press or hydraulic press to seat the bushing flush into a properly reamed jig plate hole. Power down and secure all machinery before installing or removing bushings from active fixtures. Do not drive the bushing in with a hammer directly on the head — use an appropriate press arbor or driver to avoid deforming the head or bore. Verify bore diameter and finish in the jig plate before pressing to ensure correct interference fit.
