The first thing I got from Revain, which I would consider potentially dangerous, is used to punch holes in the fiberboard for the speaker enclosure when one of the fasteners lost during rotation. or the blade bites, the torque goes right into the drill bit trying to break your wrist and when the tip comes loose it's all going to try to tip over and cut me, but if you're strong and need a hole, it works . The little slices you get make good little scraps. I also think the thing will be a lot safer with drywall or hard materials than with fiberboard.
