Boneham CB00001165 Press Fit Headed Drill Bushing Type H

Product Description

The BONEHAM CB00001165 is a Type H press fit headed drill bushing designed to guide drill bits with precision during machining and fabrication operations. It features an inside diameter of 19/64 inches, a body outside diameter of 1/2 inch, and a length under the head of 1 inch. Constructed from steel, this bushing is pressed directly into a jig plate without the need for locking mechanisms or renewable liners. The head seats flush against the jig surface to provide positive axial positioning. Machinists, toolmakers, and jig-and-fixture builders install this type of bushing in production and prototype tooling applications.

Type H headed press fit bushings are used in drill jigs where the bushing is intended to remain permanently installed in the fixture. They are suited for high-volume drilling operations in metal fabrication, aerospace, and general manufacturing environments. The head style prevents the bushing from being pushed through the jig plate during drilling. This bushing is a non-renewable design, meaning it is pressed into the jig bore and is not intended for field replacement under normal service cycles.

Key Features

• Press fit installation — no locking collar or renewable liner required
• Inside diameter tolerance of +0.0001 to +0.0005 inches for accurate drill guidance
• Headed design seats against jig plate surface to resist axial push-through
• Steel construction for durability in production drilling applications
• Head outside diameter of 39/64 inches, head height of 7/32 inches
• Non-renewable, permanent-installation bushing per industry Type H classification

Compatibility

Designed as an OEM-style press fit headed drill bushing for use in standard drill jig plates machined to accept 1/2 inch outside diameter Type H bushings per standard jig bushing industry codes.

Installation Notes

Press fit bushings require a jig plate bore machined to the appropriate interference fit tolerance before installation. Use an arbor press or hydraulic press to seat the bushing squarely into the bore — do not drive with a hammer. Verify inside diameter clearance with the intended drill or reamer before committing the bushing to a permanent installation. This bushing is not designed for field removal and reinstallation.
