Large Friction Saws are used for friction cutting cold carbon and alloy steels, usually multiple pieces. Finer tooth pitches used to generate frictional heat during cutting. High pressure cooling and clearing of teeth and generous body cooling is vital to blade operation. Blade Materials used are POWERBLADE Carbon, Manganese Steel, normalised body 22 HRC with flame hardened teeth 48 to 54 HRC. Tough crack resistant blade body combined with hard wear resistant teeth, to provide considerably increased blade life between sharpens compared to medium carbon manganese steel blades.
