I had a few projects that required me to cut through glass and metal. It’s functional and speed was exceptional, It did the job, but the more pressure you put on the bits the faster they lose Durability and drill accuracy. Keep that in mind. You get what you paid for. But the value was worth it for what I needed it for.

They wear out a little quicker and are maybe not quite as good as the wood/metal/masonry specific bits, but they get through wood, metal and masonry as advertised! Probably best in masonry

I thought they might have a hard time drilling into the concrete floor and they did but I bought a pack of 10 and the job was completed with a few left over.

As you can probably guess by the price and quantity here, these are not the best quality bits you’ll ever see, especially for the task of concrete drilling. But, if you are prepared for the fact that each might only be good for 2-3 holes, they are fine. I was able to easily finish my job with these and I had some left over. As long as they can put a hole in the masonry and not melt or start a fire from the friction, they are doing their job.

Las brocas son muy atractivas, pero no pudieron perforar de manera correcta una pared de concreto. Estaré buscando otras brocas :-/

Comenzando por el envÃo, llego mal y rota la caja en que venÃan las brocas, las brocas no cortan lo que ofrecen y el filo, al hacer un solo agujero, por lo que sirven para hacer cuando mucho un solo barreno. producto de muy mala calidad. la verdad no lo recomiendo.
