A very favorable complete set I thought to myself, and have the same ordered with my new BOSCH Impact Drill. Unfortunately, I had big problems to come with me into the outer wall (concrete). By the tedious drilling the hole is also unfortunately a bit broken, what has the stability of my project not helpful. The next day I found me a new stone-drill in the local construction market. Without problems I now could drill my holes. I was surprised how easy it is drilling with the new drill. However, one must also say that I would get the money from this 83-piece set a maximum of four drills without luggage at the hardware store.
Added to this annoying rubber mounts from which it's really cumbersome to remove the drill. In conclusion, you can also get up only the quality that you pay for. Two stars because I do not like the product and I would buy it not again.
