Boneham H264GB Press Fit Headed Drill Bushing Steel

Product Description

The BONEHAM H264GB is a Type H press fit headed drill bushing designed to guide cutting tools accurately during drilling, reaming, and similar machining operations. With an inside diameter of 0.199 inches and a body outside diameter of 13/32 inches, this bushing provides precise tool guidance in jig and fixture applications. The head outside diameter measures 1/2 inch with a head height of 5/32 inches and a length under the head of 1/4 inch. Constructed from steel, it is intended as a permanent press fit installation — no liner bushing is required. Machinists, toolmakers, and fixture builders install this type of bushing in production and maintenance environments where repeatable hole location accuracy is critical.

The H264GB is suited for use in drill jigs and tooling fixtures across general machining, fabrication, and manufacturing applications. The headed configuration seats against the jig plate surface to resist axial pull-through forces during cutting. The press fit retention method makes this bushing appropriate for permanent installations where the bushing is not expected to be replaced during the service life of the fixture. It is a single-unit item packaged individually for use in low-volume tooling builds or as a direct replacement in existing fixtures.

Key Features

• Type H headed press fit design seats flush against jig plate surface to resist axial displacement
• Inside diameter of 0.199 inches with a close tolerance of +0.0001 to +0.0004 inches for accurate tool guidance
• Body outside diameter of 13/32 inches and head outside diameter of 1/2 inch for standard jig plate fitment
• Length under head of 1/4 inch suits standard jig plate thicknesses
• Steel construction provides wear resistance during repeated drilling cycles
• Non-renewable design — intended as a permanent installation in the fixture

Compatibility

Designed as an OEM-style replacement or new-build component for drill jigs and tooling fixtures requiring a Type H press fit headed bushing with a 0.199 inch inside diameter and 13/32 inch body outside diameter.

Installation Notes

Press fit bushings are installed by toolmakers or machinists using an arbor press or hydraulic press — do not drive with a hammer, as this can damage the bushing bore or distort the jig plate hole. The receiving hole in the jig plate must be finish-reamed to the correct interference fit diameter before installation. Ensure the jig plate is secured and supported evenly during pressing to prevent warping. Once pressed in, the bushing is not intended for removal and reuse.
