With a 75,000 lb (34 tonnes) bit load capacity, the PV-271 can add unsurpassed productivity to your mining operations. The heavy duty and durable PV-271 can drill a 55 ft (16.8 m) clean hole in a single pass. Single pass drilling yields higher drilling efficiencies (up to 25% when drilling in soft material) by eliminating rod change time and allowing more time for drilling. In addition to increased efficiency, eliminating rod changes also reduces the risk for operational errors.
