I'm drilling holes in 4"x4"s in order to put magnets in them. The magnets are 1/8" deep and I'd like to install them to be flush with the surface of the wood. All I have is a Ryobi cordless drill and my bit set.
How can I drill only to a certain depth into the wood? Using a drill press would be great, but I don't have the money or the space to house one at this time.
