Recently in a post I said that I had problems with the carbide on Viper router bits when I was beveling back some laminate laid over a solid oak edge. I find now that it was not the bit but the laminate that was causing the problem. The laminate in question was made by Wilsonart (known for a very hard surface coat) for use on engineered laminate flooring. The client had gotten this laminate for nothing & wanted to use it for counter tops in some rental units. Let me tell ya this stuff is hard!! So far I've pretty much destroyed 2 Viper bits, an Amana. and a Oldham 45 bevel bits. Sorry for any confusion this may have caused.
