Boneham H205FR Press Fit Headed Drill Bushing Steel

Product Description

The BONEHAM H205FR is a Type H press fit headed drill bushing designed to guide drill bits and boring tools with precision in jig and fixture applications. It features an inside diameter of 0.185 inches (wire size 13), a body outside diameter of 5/16 inches, and a head outside diameter of 27/64 inches. The bushing is manufactured from steel for durability under repeated drilling cycles. Installation is accomplished by pressing the bushing directly into a prepared hole in a drill jig plate, where the head seats flush against the surface to establish consistent tool depth and lateral positioning. This part is a non-renewable (fixed) bushing intended for permanent installation.

The H205FR is used in metalworking, machining, and fabrication shops where drill jigs require precise, repeatable hole location. It suits applications in production drilling fixtures for both light and medium-duty operations. The headed design prevents the bushing from being pushed through the jig plate during drilling, making it appropriate for through-plate installations where a stop shoulder is needed. Machinists and toolmakers are the primary installers in job shop and manufacturing environments.

Key Features

• Press fit installation for permanent, fixed positioning in drill jig plates
• Type H headed design provides a positive stop shoulder against the jig plate face
• Inside diameter of 0.185 inches (wire size 13) with tolerance of +0.0001 to +0.0004 inches
• Body outside diameter of 5/16 inches, length under head of 5/16 inches
• Head outside diameter of 27/64 inches, head height of 1/8 inches
• Steel construction for wear resistance in production drilling applications

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for steel drill jig plates and fixture bodies requiring a Type H press fit headed bushing with a 0.185-inch inside diameter and 5/16-inch body outside diameter.

Installation Notes

Installation is performed by machinists or toolmakers using an arbor press or hydraulic press to seat the bushing into a precision-reamed hole in the jig plate. The jig plate hole must be reamed to the appropriate press fit tolerance to achieve proper interference. Confirm the bushing is fully seated with the head flush against the plate before use. Do not drive the bushing with impact tools, as this can damage the head or distort the inside diameter.
