Finally tested and used this drill bit. Only tried it on one type of stone, but it had no trouble going through. It attaches to an angle grinder which has m14 bolt (u could make a drill adapter from a bolt). Whilst using it on a angle grinder I used an autotransformer to reduce the speed, after it went through the stone some paint rubbed off of it and stayed on the stone, but that will most likely happen just on the first few stones. I would recomend buying as it worked real good for me.

For the price there are ok and the quality is also ok, but not so good like the same from brand names. If you have some smaler projects or for hobby fine, for professional use better to buy some for much more money. But you must see the price, the other ones costs a lot of more money.
