Grinding floors to prep for new covering is not what we do, but because of safety concerns my crew of Radiochemists and Health physicist are all trained to work in a problematic enviroment. We were having problems getting the floor clean enough for the next step. I called, and talked to Vince Li, he was a huge help and made good recommendations on which grinding wheel to use and how to do the work. We bought the right wheel and have finally finished the floor. We now are facing the same job in a much bigger lab, and thanks to EDiamondTools we are ready. Special thanks to Vince!
