Overview

The Chicago Pneumatic CP835 is an air powered nibbler that cuts steel and sheet metal up to 0.06 inch, 16 gauge, using a 0.177 inch diameter punch running at 2750 strokes per minute. It draws 0.42 HP (310 W) and is built with a rugged cutting head for automotive sheet metal work.

A nibbler cuts by punching a series of small overlapping bites rather than shearing a continuous line, which is what lets it follow curves and cutouts in sheet metal that scissors or a straight cutter cannot. This is a specialty automotive and sheet metal tool rather than a general shop cutter, and its rated capacity, 16 gauge steel, marks the practical ceiling for what it should be asked to cut.

Who it's for

Suits automotive and sheet metal work involving curved or irregular cuts in material up to 16 gauge steel. Not intended for material thicker than its 0.06 inch rated capacity.

Pros and cons

Pros
  • Cuts curves and cutouts a straight cutter can't follow
  • 2750 strokes per minute for steady cutting speed
  • Rugged head built for automotive sheet metal work
Cons
  • Rated capacity tops out at 16 gauge (0.06 inch) steel

Performance notes

The 0.177 inch diameter punch strokes 2750 times per minute, driven by a 0.42 HP (310 W) air motor, taking small overlapping bites out of the material rather than one continuous cut. That punching action is what lets a nibbler follow a curved line through sheet metal, with its rated capacity topping out at 0.06 inch, 16 gauge steel.
