How to Stop Sawdust from Binding Up a Holesaw

This is a tip from Greg Roos from San Francisco, California, who teaches us to drill a sawdust evacuation hole. Once you’ve located the center point of the hole that you need, take the hole saw and just start the cut. You want to be able to know where the inside edge of the kerf is.
Take a 1/2-inch diameter drill and drill a relief hole for the sawdust just inside the kerf that you’ve cut with the hole saw. Now you can go ahead and make your hole without pulling the saw in an out over and over again to clear the kerf. If you’re doing this on a horizontal surface, the evacuation hole needs to be placed at the top.
