Abstract: A manually operated tool for deburring cut ends of metallic electrical tubing (EMT) and/or copper water service tubing comprising a cutting head having a pilot cylinder to fit inside the end of the tube, and a single cutting blade contoured to scrape burrs simultaneously off the inside and outside of the tube end. The cutting head is rotatably driven by a ratcheting handle having a large diameter grip radially adjustable to be positioned as pistol grip style. The deburring tool is capable of working tube ends in close quarters. The large pistol grip and ratchet action combine to operate with a reduced amount of repeated motion and do not require the tight grip of a screw driver type handle. The tool is light weight and portable in contrast to prior art deburring tools requiring a drill motor for power. The pistol grip encourages the use of the larger muscles of the arm instead of the hand and wrist to provide the rotating power.
