1. The hex drill bit is made of M35 cobalt high speed steel. The surface is coated with titanium, which has higher hardness, better wear 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. Suitable for steel, copper, aluminum, zinc alloy, cast iron, wood and plastic.5.

Twist drill bits are made of high-speed steel, which has high hardness, high wear resistance, excellent heat resistance and good bending strength. The drill bits with polished surface are easy to maintain and repair, suitable for various applications, with long tool life and faster cutting speed.The twisted spiral design along its length allows for efficient, clean chip evacuation during drilling, which helps prevent clogging and ensures smooth drilling operations. Regularly clear away the chips and debris that accumulate in the flutes of the drill bit. Extra long twist drill bits are widely used for effectively drilling wood, plastic, gypsum board, aluminum, copper, PVC, and thin iron sheet. With good cutting performance, it can ensure high working efficiency.
