There’s a Better Way: Sawdust Evacuation Hole

If you’re cutting into a piece of wood with a holesaw, you could pull the saw in and out of the cut to clear the sawdust, but there’s a better way.

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.

byhammerandhand: yep, more drills please--just like routers and bits--more is better
JohnOSeattle: the vest is made by Occidental Leather. Here's a link:
falsedawn: I guess it depends on how long it takes to get out the other drill and how many holes you're plowing with the hole saw.
