Nueva barrena de cortes angulares, caracterizada por que esté provista, en la cabeza, de tres labios o cortes formando ángulos de 120 grados, estando estos cortes dispuestos de modo que, partiendo del centro, se extienden como tres radios equidistantes, lo que hace que la presión específica se reparta entre los tres cortes, evitando roturas y asegurando la perforación suave y el rápido avance de la barrena.
