For use in extremely tight places, these tubing cutters require minimal swing around the tubing. Mini cutters can be used on copper, steel, stainless steel, and aluminum tubing. MC2GRIP has rounded corners and edges of the body are more comfortable to grip when rotating the cutter around tubing. MC3SL contains a self-feeding cutter wheel. After tightening the feed screw, the tool cuts faster by providing a more consistent cutting force on the wheel.
