Boneham P4022KQ Press Fit Headless Drill Bushing

Product Description

The BONEHAM P4022KQ is a press fit headless drill bushing designed to guide drill bits and cutting tools with precision in jig and fixture applications. Built to Industry Code P, this bushing features a 7/16-inch inside diameter and a 5/8-inch outside diameter, with an overall length of 1-3/8 inches. Constructed from hardened steel with a hardness rating of 60 to 65 HRC, it delivers the wear resistance required for repetitive drilling operations. The headless design allows flush installation within a drill jig plate, keeping the bushing profile clear of workpieces and clamping hardware.

This bushing is used in metalworking, machining, and fabrication environments where consistent hole location is critical. It is typically installed into a hardened drill jig or fixture plate and held in place by press fit interference. Machinists, toolmakers, and fixture builders working in job shops, production facilities, and maintenance departments install this type of bushing as part of precision drilling setups. The inside diameter tolerance of plus 0.0001 to plus 0.0005 inches ensures close fit with standard drill bit shanks and tool guides.

Key Features

• Bushing Industry Code P press fit headless configuration for flush jig plate installation
• 7/16-inch inside diameter with a tight tolerance of plus 0.0001 to plus 0.0005 inches for consistent tool guidance
• 5/8-inch outside diameter and 1-3/8-inch overall length for stable seating in standard jig plate bores
• Hardened steel construction rated 60 to 65 HRC for extended service life in high-cycle drilling operations
• Meets ANSI standards for drill bushing dimensions and tolerances
• Non-renewable fixed design simplifies installation and eliminates liner bushing requirements

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for use in ANSI-standard press fit headless bushing applications with a 5/8-inch reamed hole in a drill jig or fixture plate.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush into a reamed jig plate hole. The receiving bore should be reamed to the appropriate tolerance for a press fit interference with the bushing outside diameter. Never drive the bushing with a hammer directly on the face, as this can damage the bore geometry or alter inside diameter tolerance. Verify bushing seating depth and alignment before use in production drilling.
