Good Value for performance
The Nibbler performs great untill you get to the transmission hump or the flutes on the floor boards. This is when a die grinder comes in handy.
Working on a 95 Jeep Cherokee XJ Pass. side floor board.Removed from a doner jeep.
Cuts Strait and even, Leaves little chads behind for easy clean up.
Over all it is a great deal for the $.
Just use a little common sense while you are cutting and you won't brake a Cutter Head or Die, It will slowly get dull.

NICE TOOL for slicy slice
I have used this tool mostly for cutting tin roof, and aluminum sheet for my RV project, it has worked perfect every time. worth the money

Pnuematic Nibbler
I used the nibbler on 22 gauge 304 stainless. The sheet was embossed with a tread plate. For the most part the tool performed well. However performance dropped if the compressor dropped below 150 psi constant. Nibbler heads wore quickly however stainless is not a soft material.
The tool was used to cut out a backsplash for uour kitchen. I purchased 5 additional nibbler dies to complete job. The tool did the job and it was of reasonable cost even with the purchase of additional dies ($10 each).
