Boneham P566ME Press Fit Headless Drill Bushing

Product Description

The BONEHAM P566ME is a press fit headless drill bushing used to guide drill bits and other cutting tools with precision during machining and fabrication operations. Built to industry code P, this bushing features a 39/64-inch inside diameter and a 7/8-inch body outside diameter, with an overall length of 3/8 inch. Constructed from steel, it is designed for permanent installation into a jig or fixture plate without a retaining head. The inside diameter tolerance of +0.0001 to +0.0005 inches ensures consistent tool guidance and repeatable hole location across production runs. Machinists and tool-and-die professionals install this bushing where tight positional accuracy is required.

This bushing is suited for use in drill jigs across industrial manufacturing, metalworking shops, and precision fabrication environments. The headless design allows it to sit flush within the jig plate, making it appropriate for applications where a protruding head would interfere with workpiece clearance or fixturing. It is not renewable, meaning it is intended as a fixed, long-term installation rather than a field-replaceable liner. Typical applications include production drilling, reaming guide operations, and tooling fixture builds where consistent hole placement is critical.

Key Features

• Press fit installation method for permanent, secure seating in jig plates
• Headless design sits flush with the fixture surface for unobstructed workpiece clearance
• 39/64-inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches for accurate tool guidance
• 7/8-inch body outside diameter and 3/8-inch overall length for compact fitment
• Steel construction provides durability under repeated drilling cycles
• Conforms to industry bushing code P for standardized jig tooling compatibility

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for standard P-series headless press fit jig tooling applications requiring a 39/64-inch bore and 7/8-inch outside diameter.

Installation Notes

Installation is performed by machinists or tool-and-die technicians using an arbor press or similar pressing equipment to seat the bushing into a precisely reamed hole in the jig plate. The receiving hole in the plate must be machined to the correct interference fit tolerance to ensure the bushing remains stationary under tool load. The workpiece fixture should be fully secured and the press properly aligned before driving the bushing into position. Once pressed in, this bushing is not intended for removal or replacement.
