I purchased a 10" 3/8" Radius Demi-Bullnose #60/80 for my commercial wet saw. I had project that involved 5 individual landings and 4 stairways that I needed 140 tiles with a Demi-bullnose profile. I installed a threaded turn buckle type adjuster so I could have better control on the height adjustment on my wet saw. Once I installed the new Demi-Bulnose blade and set the height I was able to make the cuts without any problems. The #60/80 grit left a very smooth finish that I was more than happy with. Great product, shipped fast and on time. Very pleased. Philip Peterson, St. Paul, MN.
