Shame on Bosch, all I can say. He drilled through the mortar portion decently enough. Luckily my center was through, I did 2 more from the inside, again through the mortar. Walked outside, caught a hole through a real brick. The first hole was definitely tricky as it wasn't a mortar hole. Started on the 2nd hole, maxed out at 1/2 inch and I started seeing the tip turning red or sparking, whatever you want to call it. Yes, I didn't want to go any further. I went on to try the 3rd, utterlyβ¦
