Sounds be straight forward. I've always used a red marker to draw a line on one part of the diamond holesaw, just so I can more easily estimate the rpm. Take your time, allow it to take as long as it needs to and the result will be a nice clean hole. Listen to the sound it makes as cutting, it will change in tone if you are binding or getting ready to break through. Good luck!
