AutoCut Copper Tubing Cutter, for use with copper tubing (not for use with soft copper). This is a great tool to have when you don't have enough swing room to use a full size tubing cutter. You can cut copper tubing with less than 1 In. of clearance or you can easily handle close stub-out work. It is quicker than conventional cutters, just snap it on the tube, close the gate and turn. The cutter wheel automatically tightens as you turn the AutoCut - no knobs to twist. The cutter wheel is spring loaded to provide a constant cutting pressure, so you'll never accidentally crimp the tubing. The AutoCut has long lasting hardened steel cutting wheels that are easy to replace when the time comes.
