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.

1. The hex drill bit is made of M35 cobalt high speed steel with sharp edge. High-temperature heat treatment makes the metal drill bit has higher hardness, better wear resistance and corrosion resistance, and longer service life than ordinary drills.2. 1/4 " hex shank, which can quickly replace the drill bit, eliminates the frustration of the handle rotation on the chuck, and makes it easier to quickly lock to the chuck. It is suitable for most electric hand drills and drilling machines.3. The fully ground spiral groove design can quickly remove debris, reduce friction and heat, and drill faster. The 135 ° straight shank split point reduces walking on the working face, making drilling accurate and easy.4. Hex twist drill bits are used for applications such as DIY projects, and home maintenance.
