I have a buddy that has been looking at buying an air nibbler and I wanted to know if anyone had any good/bad experiences with any brand at all. He's been looking at the Ingersoll Rand IR325. Does anyone have any opinions on air nibblers?
Most of the affordable ones are all Taiwan, and look like they are sourced from the same factory. With that in mind I bought the $19.99 Harbor Freight one and it worked great on 20 guage...but chipped the die when I went up to 16guage. So my opinion is to just get the Harbor Freight model and stick to 20guage or thinner.
An air nibbler is a power tool used to cut sheet metal, it uses a hardened punch that reciprocates up and down through a circular die...if you stick some metal between the punch and die the punch busts a little half moon shaped piece out of the metal these bites add up and you can cut lines and shapes out of the metal.
I have a Snap-on that has been in my box for years, It works fine on flat sheet metal but if you have to go over body lines or in tight places or make a tight turn it is a pita. Sawzall with a short blade works better for most applications, plasma cutter even better...
