Bad quality
Worst quality I've ever ordered. I've missed the return time as I didn't use them for a while. Only one of them is good , other two either not fit in or fall down of the impact driver.

Buena relación calidad precio, el estuche está muy bien.Las he usado para taladrar acero inoxidable AIS316, que es un material muy duro y complicado de taladrar y han respondido mejor de lo que esperaba.

Desilusión.
No son muy buenas, quizas valgan para hacer agujeros en aluminio o en hierro. Pero en acero inoxidable no.

Funcionan muy bien, son las mejores que he tenido de este tipo. Ahora bien, son para plásticos y metales finos.
