What is a hole saw commonly used for?

There are plug-ejecting hole saws, but they’re not very common and only available in limited sizes. Then use a cordless drill to drive a 3-inch screw into each hole. Alternately, drive each screw in a little at a time. When the screws bottom out against the inside of the hole saw, they’ll push out the plug.

Can you use a hole saw without pilot bit?

you CAN use the hole saw without the pilot bit installed, but I would recommend using a drill press, and securely clamping the work. The whole idea behind the pilot hole is to keep the hole saw centered, because those little saw teeth don’t bite into the wood as well as a drillbit.
