Boneham P488KQ Press Fit Headless Drill Bushing

Product Description

The BONEHAM P488KQ is a press fit headless drill bushing designed to guide drill bits and other cutting tools with precision in jig and fixture applications. Built to industry code P, this bushing features a 0.4375-inch inside diameter, a 0.75-inch outside diameter, and a 0.5-inch overall length. Manufactured from steel and hardened to 60 to 65 HRC, it provides the wear resistance needed for repetitive production drilling. The headless design allows the bushing to sit flush within a plate or fixture body without a protruding flange. Installation is by press fit, making it a permanent, non-renewable bushing. It conforms to ANSI standards.

This bushing is suited for use in drill jigs, fixtures, and production tooling setups found in machine shops and metalworking environments. It is installed by toolmakers and machinists who require repeatable hole location accuracy across multiple workpieces. The P series headless press fit style is a common specification in both manual and CNC-assisted drilling operations where a permanent bushing without a collar is required.

Key Features

• Press fit installation for permanent, fixed positioning in jig plates
• Headless design sits flush with the fixture 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
• Conforms to ANSI standards for industry-standard interchangeability
• Bushing industry code P for straightforward cross-referencing

Compatibility

Designed as an ANSI-standard P-series press fit headless drill bushing for use in drill jigs and machining fixtures requiring a 0.4375-inch inside diameter and 0.75-inch outside diameter permanent bushing.

Installation Notes

Press fit bushings are installed by toolmakers or machinists using an arbor press to drive the bushing flush into a bored hole in the jig plate. The receiving hole must be machined to the appropriate interference fit tolerance to ensure the bushing remains stationary during use. This is a non-renewable bushing and is not intended for removal or replacement after installation. Verify bore and bushing dimensions before pressing to avoid damaging the bushing or fixture plate.
