Boneham P6422NE Headless Drill Bushing 49/64 in Id Steel

Product Description

The BONEHAM P6422NE is a press fit headless drill bushing used to guide cutting tools with precision in jig and fixture applications. Classified under industry code P, this bushing features a 49/64-inch inside diameter and a 1-inch outside diameter body. The overall length is 1-3/8 inches. Manufactured from steel, it is designed for permanent installation without a retaining head, making it appropriate where a flush or recounted surface is required. Machinists, tool-and-die makers, and fixture builders install this part in production drilling, reaming, and boring setups where repeatable hole location is critical.

This bushing is intended for use in drill jig plates and tooling fixtures in both production and maintenance machining environments. The headless, press fit design suits applications where the bushing must sit flush with or below the jig plate surface. It is a non-renewable bushing, meaning it is pressed permanently into the liner or plate and is not intended for routine field replacement. Typical installations are found in metal fabrication shops, tool rooms, and precision machining operations requiring consistent hole guidance across high-volume runs.

Key Features

• Press fit installation method for permanent, stable seating in jig plates
• Headless design allows flush or sub-flush mounting with the fixture surface
• 49/64-inch inside diameter with a tight tolerance of +0.0002 to +0.0006 inches for accurate tool guidance
• 1-inch body outside diameter with a 1-3/8-inch overall length
• Steel construction provides durability under repetitive drilling loads
• Industry code P classification for straightforward replacement and sourcing

Compatibility

Designed as an OEM-style press fit headless drill bushing conforming to industry code P standards, suitable for use in standard drill jig plates and tooling fixtures that accept a 1-inch outside diameter bushing bore.

Installation Notes

Installation is performed by machinists or tool-and-die technicians using a press or arbor press to seat the bushing flush into a precisely bored liner hole. The mating bore in the jig plate should be machined to the appropriate interference fit tolerance before pressing the bushing in place. Do not hammer the bushing in directly without a driver or press arbor, as this can damage the ID tolerance or distort the bushing body. This is a permanent, non-renewable installation and is not designed for repeated removal and reinstallation.
