Boneham P204EZ Press Fit Headless Drill Bushing

Product Description

The BONEHAM P204EZ is a press fit headless drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. It features a 0.161 inch inside diameter, a 5/16 inch body outside diameter, and a 1/4 inch overall length. Manufactured from steel with a hardness rating of 60 to 65 HRC, this bushing resists wear under repeated tooling cycles. The headless design allows for flush installation in jig plates where a protruding head would interfere with workpiece contact or fixture clearance. It meets ANSI standards and carries the industry code P for straightforward cross-referencing.

This bushing is used in drill jig applications across metalworking, machining, and fabrication environments. It is suited for production drilling setups where consistent hole location accuracy is required across multiple workpieces. The press fit installation method means the bushing is driven directly into a prepared hole in the jig plate without additional hardware. It is a non-renewable bushing, meaning it is intended for fixed, permanent installation rather than tool-change scenarios. Machinists and toolmakers working in job shops, production lines, or maintenance departments are the primary installers.

Key Features

• Press fit installation — no liner bushing or locking hardware required
• Headless design allows flush seating in jig plates with tight clearances
• Steel construction with 60 to 65 HRC hardness for extended wear life
• Inside diameter tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• Meets ANSI standards; industry code P for easy catalog cross-referencing
• Non-renewable fixed installation for stable, permanent jig setups

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for standard ANSI P-series jig plate applications requiring a 5/16 inch outside diameter press fit headless bushing.

Installation Notes

Installation is performed by machinists or toolmakers using an arbor press or hydraulic press. The receiving hole in the jig plate must be bored or reamed to the appropriate press fit tolerance before installation. Do not drive the bushing with a hammer directly on the bore face, as this can distort the inside diameter. Ensure the jig plate material and thickness are appropriate for the press fit retention force required for the application.
