A nibbler uses a punch and die to make the cut, this is perfect for tight radius cuts into steel. A 1.65 in. starter hole is all that is needed to start or start from the edge of the material. A nibbler is also what you need if you are cutting corrugated metal. The 6880 is our heaviest nibbler with 10 gauge capacity in steel and 12 gauge into stainless. When perfect cuts are what you need, look to the Milwaukee line of nibblers.
