Boneham P405JN Press Fit Headless Drill Bushing

Product Description

The BONEHAM P405JN is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Manufactured from steel with a hardness rating of 60 to 65 HRC, this bushing resists wear under repeated drilling cycles. It features an inside diameter of 0.368 inches, a body outside diameter of 5/8 inches, and an overall length of 5/16 inches. The headless design allows the bushing to seat flush within a drill jig plate without a protruding flange. Machinists and toolmakers install this type of bushing where accurate, repeatable hole location is required in production or prototype work.

This bushing is suited for use in drill jigs, fixtures, and tooling plates across metalworking, fabrication, and manufacturing environments. It is appropriate for both production shop and maintenance repair applications where consistent hole guidance is needed. The press fit installation method means the bushing is driven directly into a prepared hole in the jig body and is intended as a permanent, non-renewable installation. Bushing industry code P identifies the dimensional series for cross-reference with standard jig bushing catalogs.

Key Features

• Press fit installation — no retaining hardware required
• Headless design seats flush with jig plate surface
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Inside diameter tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• Meets ANSI standards for drill bushing dimensional compliance
• Non-renewable fixed bushing for permanent jig installations

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing conforming to ANSI press fit headless bushing standards, industry code P series.

Installation Notes

Installation is performed by machinists or toolmakers using a press or arbor press to drive the bushing into a precisely reamed hole in the jig plate. The receiving hole must be prepared to the correct interference fit tolerance to ensure the bushing seats securely without distortion. Once pressed in, the bushing is not intended to be removed or replaced. Always verify hole preparation against ANSI bushing fit specifications before pressing to avoid damaging the bushing or jig body.
