I've had this for over a year now and love and use this tool often. I've posted a video so I won't repeat the points I made in the video, but I can tell you the cutter's edges have no nicks, gaps or chips and will cut just as well as a few thousand cuts back . Please look elsewhere if you are buying them for large diameter cutting for the primary purpose of this tool and stop speaking negatively about this tool for buying it for the wrong application.
