Hello, I dont really know anything about using a drill or cutting through metal or wood. the thing is I have a project in which I have to drill some holes in 0.04in aluminum. but I really dont know if can use regular drill bits used for drilling wood to drill the holes in my aluminum chassis. do I need to buy other drill bits for cutting metal or can I use the same ones Ive seen used for cutting wood? can I even use the same kind of drills, or do I NEED a huge bench drill with stepper bits?thanks
Aluminum is softer than steel, so you could just use the ordinary bits that you use for wood, with a hand drill. For cleaner holes, you might want to put wood behind the aluminum as a backing. Also, if you squirt a drop of oil onto the drill area, that will help. If you're trying to drill a really large hole, it might be better to drill small ones, and enlarge with a round file.
