Abstract

La invención se refiere a un taladro usado para perforación en seco, caracterizado por la asimetría de las partes del borde de corte cuyas caras están en el área del núcleo del taladro (8), en particular todo su borde de cincelar (9). Esta asimetría puede ser resultado del hecho de que los bordes individuales de cincelar (11, 12) tienen longitudes diferentes. Por ejemplo, las longitudes diferentes de los bordes de cincelar individuales (11, 12) están indicadas por las dimensiones (A) y (B).
