Drill-powered nibbler - GIF

[clavius]

For the most part they like to be used on flat panels don't do especially well on corrugations. I've not used the drill powered model like the one shown, I have a pneumatic one. The one I have is more of a center shear than a nibbler. The long guide foot makes it difficult to work with corrugations. A true nibbler gnaws its way through materials by slicing off tiny fingernail trimmings with a small contact footprint, and a messy amount of ejected sharp swarth to clean up, this one may be like those for all I know

I'm guessing that this one is a nibbler like you describe rather than the center shear type you have. I have a couple of those as well, great tools. I say that based on the fact that it looks to leave a very small kerf, the lack of the long curly waste piece that the shears leave, and the really sharp turns this one seems to make.

The cuttings from a nibbler are what one of my former coworkers called the "Razor sharp half-moons of doom" due to the fact that they seem to end up everywhere, stuck in the soles of your shoes, the sides of your socks, in your pockets, etc.
