Review on DEBO Pencil Shape Deburring Copper: Achieving Precise and Smooth Finishing Results by Manuel Gfx

This pencil reamer was recommended by a high-end plumber friend. Every other kind I've ever used ranges from worse than this to useless. This works very well, doesn't stick or snag, is very easy to use and removes burrs in just a few turns. This is the only one I use now and I converted a master plumber who was fixing pipes for one of my apartments who has been using lousy splined pipes his entire life.
