HSS Step Drill Bit Straight Flut Shank

Short Description:

Step drill, also known as step drill or pagoda drill, is a device mainly used for drilling thin steel plates within 3mm. This type of drill bit can be used to replace multiple drill bits to drill holes of different diameters at the same time, and can drill large holes at the same time without changing drill bits or drilling positioning holes. The step drill needs to drill holes of different diameters as needed, and can process large holes at one time without changing drill bits and drilling positioning holes. Drilling holes in rock can be done using a step drill. In addition to being simple and compact, this tool has an easy-to-use and flexible structure, and has the advantages of high efficiency and low cost. It is frequently used in the construction and maintenance of deep tunnels and underground mining projects.

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. This drill bit ensures perfectly round holes by reducing the amount of thrust required when drilling holes of a specific size.

Eurocut drill bits are extremely resistant to heat and wear, making them even more durable. Drilling power tools enhance the drilling capabilities of machine tools, automotive tools, and industrial tools. We have a wide range of drill bits, so no matter what size round hole you need, we have a drill bit to suit your requirements. If you have questions, please feel free to contact us.
