Drill-powered metal cutter - GIF

[BuffaloJohn]

I looked at the reviews and most complained about poor quality of the device and of the cut. Most of these seem to cut fine on flat straights, but deviate from that and all best are off.

I've tried nibblers and electric shears and have had mixed results - poor results on corrugated roofing metal. Have cut over 50 pieces of corrugated roofing with a 7 1/4 circular saw with a metal cutting blade. Just make sure you have the right kind - the thinner the metal, the more teeth are needed.

My go to on metal cutting blades has been the Diablo (brand of Freud) Steel Demon blades. I have used them in my metal cutting saw and they also work great for cutting roofing metal.
