Reed's MC3 is a Mini Tubing Cutter. It has a 1/8" - 1-1/8" capacity. It weighs .4 lbs. This cutter is ideal for cutting in the tightest places, and requires minimal swing around the tubing. It can be used on copper, steel, stainless steel, and aluminum tubing. After tightening the feed screw, this cutter works faster by providing a more consistent cutting force on the wheel.
