Drill Main Drain Hole with Hole Saws

What happens here

Using hole saws of the appropriate diameter for the sink drain, drill from both the top and the bottom of the stump, using the pilot hole as a guide. The goal is to meet in the middle, creating a clean, accurately placed drain hole. For this project, a 2-inch hole saw and a 1-inch hole saw are used to create the recess for the sink drain.

Goal: Create the perfectly aligned main drain hole in the stump.
