Abstract:

A human-powered borehole drill bridges the gap between large drilling rigs and the other less-effective manual methods. Intended mainly for developing countries, the design is affordable and also extremely simple, as very little product support or spare parts will be needed. The drill uses conventional drill pipe and drill bits allowing the drill system to mimic more conventional methods of drilling and existing hardware to maintain uniformity in drilling and easier access to more drilling products.
