Boneham P6416MH Press Fit Headless Drill Bushing

Product Description

The BONEHAM P6416MH is a press fit headless drill bushing designed to guide drill bits and other cutting tools with precision during machining and fabrication operations. Manufactured from steel and hardened to 60 to 65 HRC, this bushing delivers the wear resistance needed for high-cycle production work. With a 5/8 inch inside diameter and a 1 inch outside diameter, it seats firmly into a prepared hole using an interference press fit - no head flange, no retaining ring. The headless design sits flush with the jig plate surface, making it well suited for applications where a protruding head would interfere with workpiece movement or fixturing.

This bushing is used in drill jigs and fixture plates in machine shops, tool rooms, and manufacturing environments. It is installed wherever repeatable hole location accuracy is required across multiple workpieces. The P industry code designates its dimensional series per ANSI standards, making it a standard replacement or new-build component for jig builders and toolmakers working to print. It is not a renewable bushing and is intended as a permanent press-in installation.

Key Features

• Press fit installation for permanent, rigid positioning in jig plates
• Headless design sits flush with fixture surface - no protruding flange
• Steel construction hardened to 60 to 65 HRC for wear resistance in high-cycle use
• Inside diameter tolerance of plus 0.0001 to plus 0.0005 inches for precise tool guidance
• ANSI-compliant P-series dimensions for standard interchangeability
• 5/8 inch ID, 1 inch OD, 1 inch overall length

Compatibility

Designed as an ANSI-standard P-series press fit headless drill bushing for use in drill jigs and fixture plates requiring a 5/8 inch bore guide with a 1 inch body diameter.

Installation Notes

Press fit bushings are typically installed by toolmakers or machinists using an arbor press or hydraulic press. The receiving hole in the jig plate must be machined to the correct interference fit tolerance before installation. Do not drive the bushing in with a hammer, as this can damage the ID or misalign the bushing. Removal of a pressed-in bushing will likely damage the surrounding jig plate material, as this is a permanent installation.
