First of all it doesn't even fit in the hammer drill bit socket. I had to sand the finish to match and secondly it removed the burrs. but not as shown in the pics, it only takes off what can be taken off with a few strokes of the file, maybe it will work better with more use, I'll update my review update, it sucks instead of making it easier to use around attaching the nut after cutting the screw, it got to where I still had to use a flip disk. I would recommend taking the more expensive one, it's worth it
