Boneham P266GH Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P266GH is a press fit headless drill bushing designed to guide drill bits with precision in jig and fixture applications. Manufactured from steel with a hardness rating of 60 to 65 HRC, this bushing delivers consistent bore alignment across repeated drilling cycles. The 0.2055 inch inside diameter corresponds to wire gauge size 5, with an inside diameter tolerance of +0.0001 to +0.0004 inches for close control of tool positioning. The headless design sits flush within the jig plate, making it suitable for work where a flange would interfere. Installation is permanent — this is a non-renewable bushing pressed directly into the jig body.

This bushing is used in production drilling jigs and fixtures in industrial, tool-and-die, and precision machining environments. It is installed wherever repeatable hole location is required and a permanent, flush-mount bushing is preferred over a renewable slip type. The 13/32 inch outside diameter and 3/8 inch overall length suit standard jig plate thicknesses common in light-to-medium production tooling. Machinists, tool makers, and fixture builders are the primary installers.

Key Features

• Press fit installation method for permanent, rigid seating in the jig plate
• Headless design mounts flush — no flange to interfere with workpiece or tooling
• 60 to 65 HRC hardness provides wear resistance through repeated drill passes
• Inside diameter tolerance of +0.0001 to +0.0004 inches ensures precise tool guidance
• Non-renewable construction — intended as a fixed, long-service installation
• Meets ANSI standards for drill bushing geometry and dimensional accuracy

Compatibility

Designed as a standard ANSI-conforming press fit headless drill bushing suitable for use in jig plates and fixtures requiring a permanent P-series bushing with a 0.2055 inch bore.

Installation Notes

Installation is performed by pressing the bushing into a precision-reamed hole in the jig plate using an arbor press — never drive with a hammer directly on the bushing bore. Verify the receiving hole diameter matches the 13/32 inch outside diameter to the required interference fit before pressing. Once installed, this bushing is not intended for removal or replacement. Follow applicable shop safety procedures and power down any associated machinery before working on fixtures.
