A hole saw attachment cuts perfectly round holes into wood using your drill. It only takes a few seconds to make a hole, but what takes the most time is freeing that wood plug from the saw. Here's an easy and methodical way to clear your hole saw so it's ready for the next cut.
Hole saws have openings on the side so you can stick in a slotted screwdriver to work out a stuck wood plug. It's frustrating, but eventually you'll get the wood out. There's no easy way to do this, but the following techniques uses a different approach that doesn't require a screwdriver.
Drill two pilot holes on either side of the hole saw's pilot bit. Then drive a couple of long deck screws into the pre-drilled holes. Once they bottom out against the hole saw, they will lift the plug out. Go easy with a few turns on each side before pulling out the plug.
Unfortunately, this will only work for hole saw plugs on the larger side — smaller ones won't be quite so simple. Check out the video to see this trick in action.
