Special Hinged Cutters™ with an extra helper handle allow two people to make a team effort for bigger, tougher cuts. Hinged Cutters™ feature four wheels to cut steel, stainless steel, cast and ductile iron with only 90 deg to 110 deg handle swing. These models are ideal for cuts on well casing. Strong guide fingers ensure perfect wheel alignment for square cuts. A closed 360 deg frame on the hinged cutter forces all energy into cutting the pipe for maximum efficiency. There is no shower of sparks in this cold cut. Reed has the only hinged cutter that tracks every time and the only one recommended for ductile iron, steel, and stainless steel to Schedule 100. The Hinged Cutter™ is a Reed invention.
