Boneham PT8810OM Headless Drill Bushing 31/32 Id 1-3/8 Od

Product Description

The BONEHAM PT8810OM is a press fit headless drill bushing designed to guide drill bits with precision in jig and fixture applications. Manufactured from steel, this Industry Code P bushing installs without a head or flange, seating flush within a drilled or reamed hole for a clean, low-profile setup. The inside diameter is 31/32 inches with a tolerance of plus 0.0002 to plus 0.0006 inches, ensuring consistent drill guidance and minimal tool wander. The body outside diameter measures 1-3/8 inches and the overall length is 5/8 inches. Machinists, tool and die makers, and maintenance technicians install this type of bushing when fixture height is limited or a smooth top surface is required.

This bushing is suited for use in production drilling fixtures, jig plates, and tooling setups where repeatable hole location is critical. The headless design makes it appropriate for applications where a protruding flange would interfere with workpiece clearance or fixturing surfaces. It is a non-renewable style, meaning it is pressed permanently into the fixture plate. Typical environments include machine shops, fabrication facilities, and maintenance toolrooms handling steel, aluminum, or similar materials.

Installation Notes

Press fit drill bushings are installed by machinists or toolmakers using an arbor press or similar controlled-force equipment. The receiving hole in the fixture plate must be reamed to the appropriate press fit tolerance before installation. Once pressed in, the bushing is not intended for removal or reuse. Verify inside diameter tolerance compatibility with the drill or reamer being guided before installation.
