High Hardness Hexagonal Shank Cobalt Twist Drill Bit

These high-hardness hex shank cobalt twist drill bits are specifically designed for work scenarios requiring excellent wear resistance and outstanding cutting performance. Made from high-quality cobalt-containing high-speed steel, these bits excel in drilling stainless steel, aluminum alloys, die steel, copper, steel plates, and cast iron. The spiral flutes design significantly enhances drilling efficiency, ensuring smooth chip removal and extended drill bit life. The standard hex shank design not only improves holding stability but also significantly reduces the risk of slipping.
