Boneham P566LK Press Fit Headless Drill Bushing

Product Description

The BONEHAM P566LK is a press fit headless drill bushing designed to guide drill bits and other cutting tools with precision in jig and fixture applications. Classified under industry code P, this bushing features a 0.500 inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches, ensuring accurate tool guidance and repeatable hole location. The body outside diameter measures 0.875 inches and the overall length is 0.375 inches. Manufactured from steel hardened to 60 to 65 HRC, the P566LK delivers the wear resistance required for production drilling and reaming operations. It is installed directly into a drill jig plate without a locking collar or head flange.

This bushing is suited for use in drill jigs, fixture plates, and tooling setups where a flush or headless profile is required. The press fit installation method allows the bushing to be driven into a pre-bored hole in the jig body, making it appropriate for permanent or semi-permanent tooling configurations. Machinists, tool and die makers, and fixture builders working in light manufacturing, metal fabrication, or production shop environments are the primary installers. The headless design keeps the bushing face flush with the jig plate surface, which is useful when clearance above the plate is limited.

Key Features

• Press fit installation — no locking collar or head required
• Headless design for flush mounting in drill jig plates
• Steel construction hardened to 60 to 65 HRC for extended tool life
• Inside diameter tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• Meets ANSI standards for drill bushing dimensions and tolerances
• Non-renewable fixed bushing — intended for permanent press fit applications

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for drill jigs and fixture plates requiring a P-series headless press fit bushing with a 0.500 inch inside diameter and 0.875 inch outside diameter per ANSI standards.

Installation Notes

Installation is typically performed by a machinist or tool and die maker using an arbor press or hydraulic press to drive the bushing into a properly sized and finished bore in the jig plate. The receiving bore should be machined to the specified interference fit tolerance for the P-series bushing before installation. Verify the bore is clean and free of chips or burrs prior to pressing. Once installed, the press fit bushing is not intended to be removed and reused.
