what kind of drill can drill through metal quickly?

Great question! If you’re looking to bore a hole through something, you probably want a rotary drill. These drills use a drill bit attached to a powered rotary device, like a motor, to cut through metal. This kind of drill is powered by compressed air or electricity, and will have a chuck for holding the bit. If you search the web for “rotary drill”, you’ll find that these can be extremely heavy-duty drills capable of cutting through a lot of metal.
