The drilling is going great. I had to use padded gloves in twist mode because the vibration was crazy. I put on fingerless weightlifting gloves with canvas gloves over them then tried hammer mode and I was comfortable and probably drilled an inch in 15 seconds. The things people were telling me about drilling a 1" hole with a hammer drill are wrong. If you just have a few 1" holes to drill, you don't even need a hammer drill. I drilled a 1/2" pilot hole which may have helped, and padded gloves are a must.
