Boneham P326GB Press Fit Headless Drill Bushing

Product Description

The BONEHAM P326GB is a headless press fit drill bushing designed to guide drill bits with precision in jig and fixture applications. Manufactured from steel, this Industry Code P bushing features a 0.199 inch inside diameter and a 0.5 inch outside diameter, with an overall length of 0.375 inches. The press fit installation method provides a secure, permanent seat in the drill jig plate without requiring a locking collar. Machinists, toolmakers, and production shop technicians install these bushings when building or maintaining drill jigs for repeatable hole location accuracy.

This bushing is suited for use in drill jigs, assembly fixtures, and production tooling where a permanent, renewable-free guide is required. The headless profile allows the bushing to sit flush with the jig plate surface, making it appropriate for close-clearance setups where a flanged head would interfere with workpiece positioning or chip clearance. Typical installations are found in metal fabrication, aerospace tooling, and general machining environments.

Key Features

• Industry Code P headless design for flush, low-profile installation
• Press fit installation method for permanent, collar-free retention
• 0.199 inch inside diameter with a tolerance of +0.0001 to +0.0004 inches for precise drill guidance
• Steel construction for hardness and wear resistance in production environments
• 0.5 inch outside diameter and 0.375 inch overall length for compact fitment
• Non-renewable design intended for fixed, long-term jig plate installation

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for drill jigs and fixtures requiring an Industry Code P, headless, press fit bushing with a 0.199 inch inside diameter and 0.5 inch outside diameter.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press to drive the bushing into a precisely reamed hole in the jig plate. The receiving hole must be machined to the appropriate tolerance for a press fit to ensure the bushing seats without rotation or movement during service. Do not hammer the bushing in freehand, as this can cause misalignment or damage to the bushing bore. Once pressed in, this bushing is not designed for removal and reinstallation.
