The Fireblade and Airblade lines, whose technology was developed in Brazil, are used for hot and friction sawing or cold cutting of metallic material on continuous production lines. In this application, very high cutting speeds and low feeds are used, resulting in fast, clean cuts. These saw blades are manufactured with diameters of up to 2200 mm. The FIREBLADE friction saw blades have an extremely efficient material structure due to the patented thermo-chemical process. In comparison with conventional friction saw blades, this line of saws has the following advantages: longer useful life; less cracking due to the ductility of the material structure and the special tensioning; and the high surface quality of the cut piece, which is suitable for steels with tensile strength of up to 850 N/mm².
