It is made from high speed steel and is heat treated to increase hardness, tensile strength and cutting life. The high-speed steel is strong and sharp, and the 135-degree tip design ensures high precision and stability as well as sharpness and anti-slip properties, extending the service life. It won't bend like a long drill bit because it's stiff. Featuring chip flutes and a highly rounded back edge, this drill is ideal for drilling into metal, producing precise, clean holes. In addition to improving performance and efficiency, the stepped design increases drilling speed. Unbreakable, extremely durable and adaptable.
