The GREEN GIANT diamond blades have a jumbo 15mm segment allowing maximum life on this diamond saw blade. These premium diamond blades have a heavy duty universal medium bond. Meaning weather your cutting cured concrete or asphalt these blades have great life. These are not your usual green giant diamond blades you see on the market today. They are laser welded (NOT SINTERED). This means if you do end up running the diamond blade hotter than usual the laser weld will hold the bond to the core more efficiently.
