How to Use a Drill Press Machine: A drilling machine comes in many shapes and sizes, from small hand-held power drills to bench mounted and finally floor-mounted models. They can perform operations other than drilling, such as countersinking, counterboring, reaming, and tapping large or small holes.
Place the metal on the table of the drill press workstation. Place a piece of scrap wood under the metal to catch the drill bit when it goes through. Clamp the metal in place. Oil the metal where the hole will go, to provide lubrication. Drill a hole, slow and steady, through the metal, using a metal drill bit.
