A double-head drill is a drill bit used to process holes, usually consisting of two drill bit parts. The design of this drill bit allows drilling in two directions at the same time, improving drilling efficiency. The material is high speed steel, which is heat treated to increase hardness, tensile strength and cutting life. Additionally, the drill bit’s 135-degree tip design ensures high precision and stability while also providing sharpness and anti-slip properties, extending its service life. The drill bit is stiff and won't bend like a long drill bit.Featuring chip flutes and a highly rounded back edge, this drill is ideal for drilling metal, producing precise, clean holes. In addition to improving performance and efficiency, the rotary design increases drilling speed. The tapered handle is designed to fit snugly and won't break easily, making it extremely durable and adaptable. This drill ensures perfectly round holes by reducing the amount of thrust required when drilling holes of specific sizes by 50%. The bit is designed with a hexagonal shank to reduce chuck rotation and has size identification markings on the bit shank.
