La perforadora funciona genial.. hace perforaciones perfectas y muy rápido. La he utilizado para pletina de cobre de 10 mm y para hierro de 10 mm y 5 mm y funciona perfecta. He tenido un pequeño problema y me lo han solucionado en muy poco tiempo.. les estoy muy agradecido. Lo recomiendo.. es mucho mejor de lo que pensaba.
