All Sterling® circular tungsten carbide tipped saw blades have a micro grain cobalt binder with a small amount of titanium for added cutting life.  They are ground to very exact tolerances for optimum performance and tool life.  All blades are resharpenable.
Non Ferrous metal cutting blades cut with fewer burrs and less heat than abrasive blades, there is no need for secondary finish grinding. The modified triple chip grind resists material build up on the tooth allowing for longer life between resharpenings.
