Have successfully drilled holes in inside of the home. Wanted to install security camera on outside wall. Finding it difficult to drill hold, even starting the hole is difficult. I understand if I am in the middle of drilling hole, I might have hit metal. Tried with speed 2 and high clutch setting and drill setting. It just made a small dent after drilling for few mins. From outside appearance, it does not look like brick, but I might be wrong as there may be a coating. Can someone tell me if I am doing anything wrong? Drill used is DeWalt and bit is cobalt

I am going only mount the camera and use the outside power outlet. So intended hole is not going to come from inside to outside. Just drilling for mounting the camera
