Drilled through 1/4" steel plate works very well for the money I honestly was surprised as I'm use to buying either Milwaukee or DeWalt products I just don't use mag drills enough to justify spending $700-$1200 for a drill. The magnet is strong but you need to give it a few seconds to really work well so be careful if it's hanging on plate.But this drill did what it was suppose to do with no problems.
