Qualità
Punte di ottima qualità, le uso sia per ferro o acciaio, e anche resina visto che lavoro nel nautico. Unica cosa che avrei dovuto notare prima, ma nulla di ché, le punte sono in pollici. Ma alla fine lavorano perfettamente e posso trapanare quasi tutto come burro

Poderosas...
Perfectas. Dude en un principio en comprarlas, pues no son tan baratas que digamos (aunque siendo justos, otras brocas con la misma cantidad de Cobalto, M42, son mucho mas caras). Despues de utilizar varias brocas de otros materiales (dizque para acero, y digo dizque porque no era verdad, se hicieron pedazos) estas hicieron el trabajo en un santiamen, sin perder filo, sin quemarse, nada. Las recomiendo para todo aquel que tiene que utilizar brocas con materiales duros, ya sea acero, acero fundido o cualquier otro metal sin importar el espesor.
