Boneham P4022JQ Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P4022JQ is a press fit headless drill bushing conforming to ANSI standards and Bushing Industry Code P. It is manufactured from steel with a hardness rating of 60 to 65 HRC, providing the wear resistance required for repetitive precision drilling operations. The bushing features a 3/8 inch inside diameter, a 5/8 inch body outside diameter, and an overall length of 1-3/8 inches. It is designed for permanent installation in drill jigs and fixtures where no head or flange is needed above the jig plate surface. Machinists, toolmakers, and maintenance professionals use this bushing to guide drill bits accurately and extend jig service life.

This bushing is suited for use in drill jig plates in production machining, toolroom fabrication, and maintenance repair operations. Its headless profile allows it to sit flush with or below the jig plate surface, making it appropriate for applications where a projecting head would interfere with workpiece clamping or fixture clearance. The press fit installation method means it is intended as a fixed, non-renewable liner bushing installed directly into the jig plate bore without a liner bushing.

Key Features

• Bushing Industry Code P press fit headless configuration for permanent jig installation
• Steel construction hardened to 60 to 65 HRC for extended wear life under repeated drill passes
• Inside diameter tolerance of +0.0001 to +0.0005 inches for precise drill bit guidance
• 3/8 inch inside diameter accommodates standard fractional drill bit shanks
• Headless design sits flush or below jig plate surface, eliminating clamp interference
• Meets ANSI standards for drill bushing dimensions and tolerances

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for ANSI-standard drill jig plates requiring a Code P press fit headless bushing with a 3/8 inch inside diameter and 5/8 inch outside diameter.

Installation Notes

Installation is performed by machinists or toolmakers using an arbor press or hydraulic press to seat the bushing into a precision-reamed jig plate bore. The jig plate bore must be machined to the correct interference fit diameter before installation to ensure proper retention. Once pressed in, this bushing is not intended for removal and replacement. Inspect the bore and bushing for burrs or debris before pressing to avoid damaging the inside diameter tolerance.
