Tungsten carbide inverted cone burs have been widely used in industrial sectors such as machinery, automobiles, and craft engraving to process cast iron, cast steel, carbon steel, alloy steel, stainless steel, hardened steel, copper and aluminum. Since the inverted cone bur is clamped on a high-speed rotating tool for manual control, the pressure and feed speed of the carbide rotary file decide the service life and cutting effect of the tool.
