Pipe Reamers are used to deburr steel pipe before threading. The pipe reaming cone is made from tool steel and hardened for maximum life. Unique cutting edge makes this spiral pipe reamer self-feeding and easy to start and operate. Double pawl ratchets allow half the rotation to engage the teeth. The two pawls work to alternately engage the ratchet teeth and apply force, for optimal pipe reaming. There are thirteen teeth, equally spaced for best tooth engagement. This manual pipe reamer tool requires less work for faster results in pipe reaming.
