Boneham P6428MC Headless Drill Bushing 19/32 Id 1 Od

Product Description

The BONEHAM P6428MC is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to industry code P, this bushing features a 19/32 inch inside diameter and a 1 inch outside diameter, with an overall length of 1-3/4 inches. Machined from steel, it delivers the hardness and wear resistance required for repetitive drilling, reaming, and boring operations. The headless design allows flush seating in the jig plate without protruding above the work surface. Installation is permanent — this bushing is not renewable once pressed in.

Press fit headless drill bushings are standard components in production drilling fixtures, tooling plates, and jig assemblies across metalworking, fabrication, and machine shops. The P series is a widely recognized industry-standard classification for press fit headless types, making the P6428MC a common replacement or new-build component for fixture tooling requiring a 19/32 inch bore. Machinists, toolmakers, and fixture builders are the primary installers in industrial and manufacturing environments.

Key Features

• 19/32 inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• 1 inch outside diameter with a 1.0000 inch decimal dimension for consistent press fit seating
• 1-3/4 inch overall length provides extended tool guidance depth
• Headless design seats flush with jig plate surface — no head protrusion
• Steel construction for hardness and durability in high-cycle drilling operations
• Industry code P classification — non-renewable permanent press fit type
• Not counterbored — straight-wall bore throughout

Compatibility

Designed as an OEM-style press fit headless drill bushing for use in standard P-series jig plate applications requiring a 19/32 inch bore and 1 inch outside diameter press fit interface.

Installation Notes

Press fit bushings require an arbor press or hydraulic press for proper installation into the jig plate bore — never drive with a hammer. The receiving hole in the jig plate must be machined to the correct tolerance to achieve proper interference fit. Once pressed in, this bushing is permanent and is not designed for removal and replacement. Deburr and clean the mating bore before installation to avoid damage to the bushing or the fixture plate.
