Boneham P4022KE Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P4022KE is a press fit headless drill bushing manufactured from steel, designed to guide cutting tools with precision in jig and fixture applications. With an inside diameter of 0.404 inches, a body outside diameter of 0.625 inches, and an overall length of 1.375 inches, this bushing maintains consistent hole location and drill alignment across repeated operations. It is installed using a press fit method, seating permanently into the jig plate without a locking head. Licensed machinists, toolmakers, and precision metalworking professionals use this type of bushing in production and maintenance environments where accurate drill guidance is critical.

The P4022KE carries an industry bushing code of P, which corresponds to its bore size and outside diameter pairing within the standard drill bushing series. It is suited for use in hardened drill jigs, fixture plates, and tooling blocks in both production machining and general metalworking settings. The headless design allows the bushing to sit flush with the jig plate surface, making it appropriate for applications where a protruding head would interfere with workpiece clearance or tooling access. This part ships individually and is not a renewable bushing.

Key Features

• Press fit installation for permanent, secure seating in jig plates
• Headless design sits flush with the jig plate surface
• Inside diameter tolerance of plus 0.0001 to plus 0.0005 inches for close-tolerance drill guidance
• Steel construction provides durability in high-cycle production tooling
• Industry bushing code P for standard series cross-reference
• Not counterbored and not renewable — intended for fixed, permanent installation

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard P-series press fit headless drill bushing applications in hardened jig plates and fixture tooling.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing into a properly reamed jig plate bore. The receiving bore must be reamed to the correct interference fit tolerance before pressing to avoid galling or bushing distortion. Once pressed in, this bushing is not designed for removal or replacement. Always verify bore preparation and bushing alignment before applying press force.
