Boneham P484KV Press Fit Headless Drill Bushing

Product Description

The BONEHAM P484KV 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 29/64-inch inside diameter and a 3/4-inch outside diameter with an overall length of 1/4 inch. Constructed from steel, it is installed permanently into a drill jig plate by pressing into a prepared bore, where it serves as a hardened guide to maintain accurate hole location and extend tool life across repeated drilling operations. Machinists, toolmakers, and production shop technicians are the typical installers of this component.

This bushing is suited for use in drill jigs and fixtures across metalworking, fabrication, and general manufacturing environments. Its headless design allows the bushing to sit flush with or below the surface of the jig plate, making it appropriate for applications where a protruding head would interfere with the workpiece or fixturing setup. The press fit installation method means no additional locking hardware is required, keeping the assembly compact. This style is common in both prototype and production-run tooling scenarios where consistent hole placement is critical.

Key Features

• Industry Code P classification for standardized jig bushing fitment
• 29/64-inch inside diameter with a close tolerance of +0.0001 to +0.0005 inches for accurate drill guidance
• 3/4-inch outside diameter and 1/4-inch overall length for compact installation
• Headless design sits flush or below jig plate surface to avoid workpiece interference
• Steel construction provides durability and wear resistance in repeated-use drilling applications
• Press fit installation requires no locking collar or additional hardware

Compatibility

Designed as a standard Industry Code P press fit headless drill bushing for use in drill jigs and fixtures requiring a 3/4-inch outside diameter press fit bore and a 29/64-inch tool guide diameter.

Installation Notes

Installation is typically performed by machinists or toolmakers using an arbor press or hydraulic press to seat the bushing flush into a precisely reamed or bored hole in the jig plate. The receiving bore in the jig plate must be prepared to the correct tolerance to achieve proper press fit interference. Inspect the bushing and bore for burrs or contamination before pressing to avoid galling or misalignment. This is a permanent, non-renewable bushing and is not intended for field removal and reuse once installed.
