      Is there a specific technique for drilling a hole in a Moenstone sink. I certainly don’t want to ruin it just to instal an undersink filter. I notice undereneath the sink there are already several “punch out” holes already started. How are they used? Should I ignore them and use a hole saw from the top of the sink? Thanks

      Use hole saw where knockout is.

      Yes, drill the exact same size hole from the backside up, when the pilot bit surfaces through the top, then switch to the top and cut the hole out the rest of the way.

      Use a bi-metal hole saw at a high rpm.
