Pricewise professional drill at prices that a private citizen at hobby can ill afford. Therefore, I tried it with this set and have not been disappointed. For home use, this set is quite high. As soon as you open the box you realize that this is not comparable to DIY material.
In practice, then, the drills have proven that they fully serve their purpose. The drills are very hard and very sharp. I've cut right on one, it was not used. Despite the sharpness they are very durable and after 50 holes in aluminum the drill is still almost like new.
Conclusion: I would buy this drill again. They are really worth the money and help to achieve good results. Who uses this drill again, is nothing else to buy (most even better drill of wedge like).
