Why Flood Cooling of Carbide Teeth Won't Work on Carbide Cold Saws
The carbide tips of a circular saw blade crack under extreme temperature changes, demonstrating why a flush coolant system won’t work on carbide cold saws.
The History of Carbide Sawing
The name carbide saw came from the tool, a circular saw blade, with silver soldered carbide tips. It competed with and just about replaced, solid or segmental HSS blades, because carbide is much harder than HSS. Before HSS saws were developed, abrasive, friction or hot saws were used and are still manufactured for certain applications. These processes create heat and are therefore called hot saws.
