Abstract

La presente invención se relaciona con una broca (1) teniendo un vástago de herramienta (3), un eje central (5) y una primera región de corte (7) teniendo al menos un primer filo cortante geométricamente definido (9; 9´) el cual tiene una superficie de desprendimiento (23) y está dispuesto a una distancia radial del eje central (5) de la broca (1); el primer filo cortante encierra un ángulo de avellanado (a) con el eje central. La broca (1) se caracteriza por el hecho que el primer tilo cortante (9, 9´) se asigna un escalón de formación de virutas que es formado por la superficie de desprendimiento (23) del primer tilo cortante (9; 9´) y por una superficie de talón (31) adyacente a la superficie de desprendimiento (23) e incluye un ángulo de talón (d), siendo que el ángulo de talón (d) es mayor que 90°, preferentemente mayor que 100°, porque la superficie de desprendimiento se extiende bajo un ángulo de desprendimiento (e) radial relativo a una línea (L) radial imaginaria que intercepta el primer filo cortante (9´) asociado con la superficie de desprendimiento (23) y porque el ángulo de desprendimiento (e) es positivo.
