  • DIN340 Double Relief Angle Self-Centering High Speed Steel Straight Shank Twist Drill is a professional drill designed for various drilling needs. Manufactured from high-speed steel, the drill has excellent hardness and wear resistance and is suitable for drilling a variety of materials.
    One of its features is the double relief angle self-centering design, which means that the drill bit can better fix the position during use, reduce deflection, and maintain the accuracy and stability of drilling. This feature is very important for drilling tasks that require high precision.
    The drill can have three different edge options: fully ground, milled and parabolic, which makes it suitable for different application scenarios. Fully ground and milled edge types are suitable for conventional drilling on materials with low hardness, while parabolic edge types are suitable for some difficult-to-machine materials, such as stainless steel, alloy steel, etc.
    The straight shank design allows this twist drill to be used with a variety of drill presses or drill holders, providing a solid connection for increased work efficiency and safety.
