Tools and Bits

HSS Drill Bits

High-Speed Steel (HSS) drill bits are primary cutting tools characterized by their red hardness, allowing them to maintain structural integrity and a sharp cutting edge at temperatures exceeding 600 degrees Celsius. Composed of carbon steel alloyed with tungsten, molybdenum, and often cobalt (HSS-Co), they exhibit extreme wear resistance and tensile strength. Their precise flute geometries efficiently evacuate chips while enduring high mechanical loads. They are extensively applied in CNC machining and metal fabrication for boring through mild steel, cast iron, and high-tensile alloys.
