Boneham P268GO Press Fit Headless Drill Bushing

Product Description

The BONEHAM P268GO is a press fit headless drill bushing used to guide drill bits and reamers with precision in jig and fixture applications. Classified under bushing industry code P, it features a 7/32-inch inside diameter and a 13/32-inch outside diameter, with an overall length of 1/2 inch. Machined from steel, the bushing is designed for permanent installation without a retaining head, making it suited for applications where a flush or below-surface seating profile is required. Machinists and tool-and-die professionals install this type of bushing in production drilling jigs to maintain consistent hole location across repeated operations.

This bushing is appropriate for use in drill jigs, fixtures, and tooling plates in both job-shop and production machining environments. The headless design allows the bushing to seat fully within a counterbored or straight-bored hole in the jig body. It is typically installed by pressing into a prepared hole in hardened or unhardened jig plates, and it is not designed for field removal or replacement once seated. Applications include production drilling, reaming, and light boring operations where repeatable positional accuracy is critical.

Key Features

• Press fit installation method for permanent, rigid seating in jig plates
• Headless design provides a flush or recessed profile after installation
• 7/32-inch inside diameter with a tight tolerance of +0.0001 to +0.0004 inches for consistent tool guidance
• 13/32-inch body outside diameter and 1/2-inch overall length
• Steel construction for wear resistance in repetitive drilling operations
• Non-renewable design; intended as a permanent fixture component

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jigs and fixtures requiring a press fit headless bushing with a 7/32-inch inside diameter and 13/32-inch outside diameter per bushing industry code P standards.

Installation Notes

Installation is performed by machinists or toolmakers using an arbor press or hydraulic press to drive the bushing into a precision-bored hole in the jig body. The receiving bore must be machined to the appropriate interference fit tolerance before pressing in the bushing. Once installed, the bushing is not intended for removal. Ensure the jig plate and bushing bore are clean and free of burrs or debris prior to pressing to avoid damage to the bushing or bore.
