A '''nibbler''' (or '''pair of nibblers'''<ref>{{cite book |title=ASD Technical Report |date=1963 |publisher=Aeronautical Systems Division, Air Force Systems Command, United States Air Force |page=157 |url=https://www.google.co.uk/books/edition/ASD_Technical_Report/j2mVYC5OyWkC |language=en |quote="If a motorized tool is not available, then a pair of nibblers will have to be provided. This is a hand tool with which the puncture can be progressively cut out."}}</ref>) is a tool for cutting sheet metal with minimal distortion. It may be used for "[nibbling](/source/nibbling)": cutting a contour by producing a series of overlapping slits or notches.

One type of nibbler operates much like a punch and die, with a blade that moves in a linear fashion against a fixed die, removing small bits of metal and leaving a [kerf](/source/Saw) approximately {{convert|6|mm|abbr=on}} wide.  Another type operates similar to tin snips, but shears the sheet along two parallel tracks {{convert|3-6|mm|abbr=on}} apart, rolling up the waste in a tight spiral as it cuts.  

Nibblers may be manual (hand operated) or powered. Power nibblers are often powered by [compressed air](/source/compressed_air), though electrical types also exist. A common [DIY](/source/Do_it_yourself) nibbler tool is an [electric drill](/source/electric_drill) attachment, which converts the rotary motion of the drill into a reciprocating motion of the jaw.
