I had bought these core cutter, because I wanted to have drilled in the reconstruction work at my house as soon as possible clean holes for the switch box into the brickwork. The core cutter, or as I say, the Dosensenker was delivered quickly and also came in a neat package. When I started with the Dosensenker to drill the holes for the switch box into the wall, I quickly realized that I had to constantly nachschrauben the screw holding the center drill, because the screw constantly broke. The holes even I could drill into masonry relatively quickly and cleanly with the Dosensenker, even though my Makita hammer drill was constantly rattling on. The drill with the Dosensenker worked with and without impact setting. Who the core cutter / the Dosensenker not everyday needs for countless holes is well served with this product. The price / quality ratio is perfectly fine and therefore this product is for people who sometimes use to recommended it.
