As an industrial and scientific user, I am always on the lookout for quality cutting tools. This deburring cutter exceeded my expectations as my tests showed it effectively removed burrs and created smooth edges on non-barrier tubing. The design made it easy to handle and control during use. The only drawback is that it may not fit all sizes of tubing, but for those it does, it is a fantastic tool.
The "dimples" for each size are too large making a straight bevel cut impossible. And to make matters worse, the cutter at the bottom of each hole does little to nothing to bevel the edge of the copper tubing if you can make contact. Totally useless.
