Boneham P568MC Press Fit Headless Drill Bushing

Product Description

The BONEHAM P568MC is a press fit headless drill bushing designed to guide drill bits and reamers with precision in jig and fixture applications. Built to Industry Code P specifications, this bushing features a 19/32-inch inside diameter and a 7/8-inch outside diameter, with an overall length of 1/2 inch. Manufactured from steel, it is pressed directly into a drill jig plate without a head flange, keeping the top surface flush. Machinists, tool and die makers, and production line technicians install this type of bushing when consistent hole location accuracy is required across repeated operations.

This bushing is suited for use in drill jigs on production floors, machine shops, and fabrication environments where tight positional tolerances must be maintained. The P-code designation places it within a standardized sizing family, making it a straightforward fit for jigs designed around that industry-standard series. It is intended for permanent or semi-permanent installation in ferrous and non-ferrous workholding fixtures. Applications typically include drilling, reaming, and light countersinking operations in both manual and CNC-assisted jig setups.

Key Features

• Press fit installation method for secure, flush-mount seating in drill jig plates
• Headless design keeps the bushing top surface flush with the jig plate face
• 19/32-inch inside diameter with a close tolerance of plus 0.0001 to plus 0.0005 inches for consistent tool guidance
• Steel construction provides hardness and wear resistance for repeated drilling cycles
• Industry Code P designation ensures dimensional compatibility with standard P-series jig plates and liners
• Compact 1/2-inch overall length suits thin jig plates and tight-clearance fixtures

Compatibility

Designed as an OEM-style replacement or original-fit bushing for drill jigs and fixtures built to Industry Code P headless press fit specifications.

Installation Notes

Press fit bushings are typically installed by a machinist or tool maker using an arbor press or a bushing driver tool. The jig plate bore should be finished to the appropriate tolerance before pressing to avoid distorting the bushing ID. Always press the bushing squarely into the bore to prevent cocking, and verify the ID remains within tolerance after installation using a calibrated plug gauge.
