Review on Machine Sharpened THINSET REMOVAL 0 401 by David Golden

It really isn't sharp enough to get the job done and the material isn't as hard as metal to withstand the tests this tool has to put through. In the end it didn't work for me. I used the narrower bit to push the tile out and then used the bit on the sander to remove the remaining thin layer. This process was much faster than the broad bit. The wide bit broke the tile into small pieces and did absolutely nothing when it came to removing the thin part. The cutting edge also wore out quickly until it became blunt. It really should have a sharper edge and be made of a hardened material to withstand impact.
