    Bad quality
  

*by S***V on Reviewed in the United Kingdom on 7 October 2019*

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.
