Review on Diamond Cutting Porcelain Diamond Stoneware by David Dober

Failed to load media. As a test I fitted an S&R blade to an 11 amp angle grinder and cut some very hard concrete slabs as well as softer tile. It effortlessly cuts through concrete and stone slabs like paper! Watch the attached video. The angle grinder didn't even get warm because the blade offers very little cutting resistance and the motor didn't have to work as hard. Also, the blade has not worn noticeably after several cuts. The cut-off wheel would have worn down to zero. The cost is $18 which seems expensive when comparing blades of similar specs!
