Contact us for Quality Roofing Contactractors
Ever wonder about the best way to cut corrugated sheet metal or deep trapezoidal roofing and siding material? We compare a jigsaw, reciprocating saw, and 6-inch grinder against the 12V cordless Trumpf N 160 Li-ion Nibbler. We realize other methods exist as well (diamond wheels, power cutters, shears, etc), but we wanted to show you at least some of the common ways people cut this material in the field.
After you see our results, you may just want to run out and get your own Trumpf nibbler and save a lot of hassle, vibration, noise, and sparks. If you need cordless freedom—a 12V nibbler might be the best tool for this type of work.

Of course the further away from the edge of the table, the more shaking.
… for 10 Sterling pounds I bought a nibble which I can put in to combi drill and to cut I upsides down to see the marking line.
I go the other direction with the grinder.
I miss the Milwaukee M18 FCMS Steel Cutter
try cutting two metre in from the end with the nibbler or two yards and see how you go
Thanks now I am going to hijack TV
The plastic on the jigsaw base gets metal shavings lodged in it and it scratches wooden surfaces.
If that was 29 gauge steel I think you would have a lot more trouble with some of those tools.
I prefer a dual saw. It cuts fast and accurately
A mini-grinder with a diamond blade works fine, Drag is through the material, don’t push.
Never cut colourbond with a angle grinder it cooks the paint. If you have to cut It 10mm long and trim with tin snips.
Good feedback!
Surprised you didn’t time the cuts
What about differences in noise?
Thanks, I wanted to know exactly what you demonstrated!. Would have been a cherry on the top if you also had the circular saw in the mix! But, much appreciated otherwise.
I’ve always used a circular saw with an old blade installed backwards. Always worked great.
A circular saw is definitely the most accurate for cutting roofing iron. It’s a question of whether you can source a special metal wheel or not. I used my worn out timber saw wheel, I found once the heat was generated, it cut through smoothly and the diameter of the blade over rode the difference in the corrugations.
Glad it was helpful!
Wear eye and ear protection when grinding , cutting , metal roofing.
Especially the ear protection.
Breathing protection too! don’t be an idiot, wear your PPE!
I know Union Trained Chicago Plumbers that can make a laser cut with a Sawzall. Then again, the same tool used all day.
The nibbler has an advantage not mentioned over all the other tools, it has a shearing action which means when you cut galvanized sheets it will roll the galvanizing over the cut edge, this prevents rust.
With practice the nibbler get easier to use. I have the 18v Makita and love it
Good video.
How much does it cost to replace the nibbler jaws? The other methods are inexpensive to replace blade/ wheel.
The heat from the grinder will ruin the paint and make it rust. Or have I heard wrong.
