2,600 stroke/minute motor provides fast cutting action in steel up to 18 gauge. The 6350 has the smallest cut radius of any nibbler at only 3/16" allowing clean cuts in tight corners. The "over sized" anvil and punch dramatically increases the reliability of these high wear parts. Includes an additional punch. Composite handle and throttle lever design provide comfortable and convenient operation. The rotational 360? rear exhaust muffler allows exhaust air to be directed as preferred. Precision engineered components make this tool suitable for high volume.
