Quick Tip 1: Using diamond hole saws, it does not matter which way you run your drill. If you are concerned with the nuts unscrewing, we suggest you run drill in reverse (counter-clockwise). This will prevent nuts from unscrewing.
Quick Tip 2: You do not need the guide for the entire duration of the drilling. Once you have made a mark on the material, the hole saw will keep in position.
Quick Tip 3: Do not forget to use water. It is OK to stop drilling for a cleanup and cooling.
