Boneham P8812NU Press Fit Headless Drill Bushing

Product Description

The BONEHAM P8812NU is a press fit headless drill bushing manufactured to Industry Code P standards. It is used to guide drill bits and cutting tools with precision during machining and fabrication operations. The bushing features a 55/64 inch inside diameter with a tolerance of positive 0.0002 to positive 0.0006 inches, a 1-3/8 inch body outside diameter, and a 3/4 inch overall length. Constructed from steel, it is designed for permanent installation in jig plates and fixtures. Machinists and tool and die professionals install this bushing type in production environments where repeatable hole location accuracy is required.

This headless drill bushing fits flush with the surface of a drill jig or fixture plate, making it well suited for applications where a protruding head would interfere with workpiece movement or fixturing. It is appropriate for use in metal fabrication shops, machine shops, and production environments that require consistent drill guidance across multiple parts. The press fit installation method provides a secure, non-renewable fit intended for high-volume or long-run applications where the bushing position will not need to be changed.

Key Features

• Industry Code P headless configuration sits flush with the jig plate surface
• Press fit installation for secure, permanent seating in the fixture
• 55/64 inch inside diameter with tight tolerance of positive 0.0002 to positive 0.0006 inches for precise drill guidance
• Steel construction provides durability under repeated drilling cycles
• 3/4 inch overall length suits standard jig plate thicknesses
• Non-renewable design intended for fixed, long-run production setups

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jigs and fixtures requiring an Industry Code P press fit headless bushing with a 55/64 inch inside diameter and 1-3/8 inch outside diameter.

Installation Notes

Installation is typically performed by a machinist or tool and die professional using an arbor press to drive the bushing into the prepared hole in the jig plate. The receiving hole must be machined to the correct interference fit tolerance before installation. Once pressed in, this bushing is not designed for removal or replacement. Always verify hole location and bushing orientation before pressing to final depth.
