Broca
La elección de la broca correcta
Existen diferentes tipos de brocas en función de la geometría del orificio que se desee perforar y de los materiales mecanizados.
El término broca designa la herramienta utilizada para perforar el metal. En el caso de la madera o de los materiales minerales (hormigón y otros), se utiliza también el término mecha (para madera y para hormigón).
- Broca escalonada: para desbarbar agujeros redondos, perforar agujeros de diferentes diámetros con una sola broca o ensanchar agujeros existentes.
- Broca de biselado o desbaste: para eliminar las aristas vivas o para cubrir cabezas de tornillos.
- Broca de centrado/marcado: para evitar el pretaladrado.
