Utilizzabili per materiali non acciaiosi. preferibilmente ferro di piccolo spessore, lego, plastica.

davvero eccezionale, fora senza difficoltà vari materiali, provato a forare una vecchia chiave inglese: fatto tranquillamente lubrificando la punta. salvo eccezioni userò sempre questa punta al posto di quelle classiche
