I immediately started using this on a PVC project and although it cuts the ends it also cuts odd grooves in the PVC. I found small burrs near the cutting edge on the aluminum body that were not removed during the initial milling. I removed the cutting blade and used a file to remove the burrs and dull the sharp edges of the aluminum. After this adjustment it works wonderfully. In my opinion, this setting is not necessary for an instrument in this price range.
