The twist drill bit is made of high-speed steel (HSS) and cobalt (CO) alloy, has high hardness and durability, can easily cut hard metals, and has a long service life. It has good wear resistance, maintains stable cutting performance under high-speed rotation and high-temperature environments, and is not easy to deform. After the surface is baked yellow, it is smoother, reducing the friction resistance between the tool and the workpiece and improving the cutting efficiency.The spiral groove design can effectively discharge the cutting chips generated during the processing and reduce vibration and material jamming.
