  • TiAIN Coating: The surface of the step drill bit set for metal heavy duty is coated with a layer of TiAIN, which can minimize the wear of the drill bit during each drilling process. The hardness of the 89HRC surface has also improved to a higher level, which can cut harder materials and greatly improve the cutting speed
