Diamond Blades for Abrasive Materials

Our Premium asphalt blades were originally developed for dry cutting in the US market, so are tough and durable and can operate with reduced water that you sometimes get on site. Our UDT black diamond blade is our hardest bond for cutting abrasive materials like asphalt, natural limestone, cinder blocks and green (uncured) concrete. It has undercut protection using an "R" segment (undercut protection reduces the chances of the blade biting or kicking back, or segments coming off) and uses 10mm diamond asphalt bond segments. These blades are ideal for use on quick-cuts (handsaw) and is also handy as a wall chasing blade.
