Material - The hex drill bit is made of M35 cobalt high speed steel with sharp edge. The surface is coated with titanium, which has higher hardness, better wear resistance and longer service life than ordinary drills.
Feature - 1/4 " hex shank, which can quickly replace the drill bit. 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.
Application - Hex twist drill bits are used for applications such as DIY projects, and home maintenance. Suitable for steel, copper, aluminum, zinc alloy, cast iron, wood and plastic.
Note - Please keep cool and gentle using, the working life of the twist drill bits can be largely prolonged by proper usage.
