Designed to perform radial cuts on 1/4 to 3' copper, brass, aluminum, and plastic tubes, this Jonard Tools TC-300 Tube Cutter is perfect for cutting open fiber optic ducts and other tubes without damaging anything inside them. This tube cutter features four roller bearings that securely hold tubes in place while cutting. A quick release push button disengages the tool from the pipe quickly and easily, while a removable reamer is stored neatly in the handle for deburring and reaming after cutting. The cutting wheel can be removed easily without tools, and an included spare cutting wheel is stored within the knob for convenience.
