The General Wire ATC34 3/4" Copper AutoCut 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 one inch of clearance. And it's ideal for stub-out work. The ATC34 AutoCut is quicker than conventional cutters. Just snap it on the tube, close the gate and turn in either direction. 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. Keep both a 1/2" and 3/4" AutoCut in your toolbox. Watch out though, they'll spoil you.
