Boneham P404KG Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P404KG is a press fit headless drill bushing designed to guide drill bits and cutting tools with precision in fixed jig and fixture applications. Built to ANSI standards, this bushing features a 13/32 inch inside diameter, a 5/8 inch body outside diameter, and a 1/4 inch overall length. Manufactured from hardened steel with a hardness rating of 60 to 65 HRC, it provides wear-resistant guidance for repetitive drilling operations. The headless design allows flush seating within a jig plate. The inside diameter tolerance of +0.0001 to +0.0005 inches ensures accurate tool alignment across production runs.

This drill bushing is suited for use in drill jigs and fixtures across machining, metalworking, and fabrication environments. The press fit installation method makes it appropriate for permanent or long-run applications where the bushing is not intended to be routinely replaced. It is installed directly into a prepared hole in a jig plate without the need for a locking mechanism. Machinists and toolmakers in production shops and maintenance operations are the primary installers of this component.

Key Features

• Press fit installation for permanent, fixed-position seating in jig plates
• Headless design allows flush installation with the jig plate surface
• Hardened steel construction rated 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 dimensions and tolerances
• Compact 1/4 inch overall length suits thin jig plate applications

Compatibility

Designed as an OEM-style press fit headless drill bushing conforming to ANSI P-series specifications for use in standard drill jig and fixture plates.

Installation Notes

Installation is performed by machinists or toolmakers using a drill bushing press or arbor press. The receiving hole in the jig plate must be machined to the correct tolerance for a press fit to ensure the bushing seats securely without damage. Verify the hole is clean and free of burrs before pressing the bushing into position. Do not hammer the bushing directly without a proper driver to avoid distortion of the bore.
