The reinforced concrete pipe blade is great for cutting ductile iron. It provides a fast, smooth cut on ductile iron pipe. The blade is designed to eliminate pinching of the pipe with silicon carbide electroplated on to the core. The reinforced concrete pipe blade cuts twice as fast as an abrasive blade and is much safer to use. Fewer blade changes are necessary and the cost per cut is drastically lower than abrasive blades. This saw blade is perfect for the professional who uses his diamond cutting tools regularly.
