Review on Toolocity Diamond Profiler VPE0316 - 16 Inch by James Nedumaran

With little technique, this is a great tool for adding a beveled edge. Burn marks or scratches can appear on the quartz if you spin one of the smooth ball bearing guides quickly with the diamond bur. (It might have been better if the top rail was plastic, otherwise there probably wouldn't be as deep scratches) but I've found that a slight 1-2 degree raising eliminates almost all of these issues. . But usually when someone buys this bit they are also experienced and polished to make a great finished project. As a fabricator/installer, he paid for himself 8 times on his first job. Homeowners pay big bucks per foot for a stylish beveled edge. By far my favorite edge type.
