Boneham PT368IF Headless Drill Bushing 19/64 in Id Steel

Product Description

The BONEHAM PT368IF is a press fit headless drill bushing manufactured from steel, designed to guide cutting tools with precision during drilling, reaming, and boring operations. Assigned industry code P, this bushing features a 19/64 inch inside diameter and a 9/16 inch outside diameter, with an overall length of 1/2 inch. The headless profile sits flush within the jig plate, making it well suited for applications where a protruding head would interfere with the workpiece or fixturing. Machinists and toolmakers rely on this type of bushing to maintain accurate hole location and extend the service life of drill jigs across repeated production runs.

The PT368IF is used in drill jig assemblies across metalworking, fabrication, and machine shop environments. Its press fit installation method allows it to be permanently installed into a hardened or unhardened jig plate without the need for a liner bushing. The compact 1/2 inch overall length suits applications with limited plate thickness or where minimal bushing protrusion is required. This bushing is appropriate for both prototype fixturing and volume production tooling setups.

Key Features

• 19/64 inch inside diameter with a tight tolerance of plus 0.0001 to plus 0.0005 inches for precise tool guidance
• 9/16 inch outside diameter for secure press fit installation in the jig plate bore
• 1/2 inch overall length fits applications with restricted plate thickness
• Headless design sits flush with the jig plate surface, eliminating interference with the workpiece
• Steel construction provides wear resistance under repeated drilling cycles
• Industry code P classification for straightforward cross-reference and replacement

Compatibility

Designed as an OEM-style replacement for press fit headless drill bushings conforming to industry code P specifications in standard drill jig assemblies.

Installation Notes

Press fit bushings are installed by machinists or toolmakers using an arbor press or hydraulic press. The mating jig plate bore must be machined to the proper interference fit tolerance before installation. Do not hammer the bushing directly without a proper driver to avoid damaging the bore or distorting the bushing. Once pressed in, this bushing is not intended for removal and reuse.
