The heat treatment gives our friction saw blades a hardness of between 42 and 46 Hrc depending on the application and the material to be cut. Because of the high temperatures, to maintain the saw blade stability it’s necessary to ensure the tool is the correct dimension in order to avoid blade deformation due to heating towards the edge. Our engineers recommend keeping the right ratio between diameter and blade thickness. As for the number of teeth and the pitch, we normally suggest pitch 5 or 6 mm for thin wall pipes and 7 or 8 pitch for bigger wall pipes. The plastic conditions of the material to cut influence the friction saw blades parameters. Our technicians can suggest the right cutting speed and feed for the different applications.
