Bits can and will grab workpieces which can whip them out of hand and cause damage to the drill press, the stuff around it, and you. A simple vise will make drilling precision holes easier and safer.

If you have a drill press, drill the 12 small holes with that, using a ⅛-inch bit, or whatever size in that range you have. If you use a hand drill, make sure it’s straight up and down.

It has a screw shaped end point. Not as clean cut as a twist or flat bit. It is used with a hand drill: Wood: Hole saw: Comprised of a twist drill surrounded by a large circular tube with a saw teeth.
