I'm interested in upgrading my slow speed 8" grinder to a new CBN wheel (Cubic Boron Nitride). I have checked out both D-Way tools 8x1 1/2" and Craft supplies Raptor model 8x1" wheels. Both are similar except for the width as the D Way is 1 1/2 inches wide as apposed to the 1" wide Raptor from Craft Supplies. Also Raptor has a large side grind area on the side of the wheel which appeals to me. I did note that D-Way's CBN also claims it can grind carbon steel where-as Craft Supplies Raptor cannot. Does anyone have pros or cons either way with either of the two wheels or another option available, any suggestions a bit confused here? Thanks Jim Lwood
