   However, HSS blades use coolant and the cut surfaces don't get hot, thus called cold saws. With the unique geometry of the teeth of carbide circular saws, the heat, developed by the cutting process is transferred into the chips and carried away with the chips. The cut surfaces stay cool. Therefore, carbide saws were also called cold saws.
