HSS Step Drill Bit Spriral Flut Straight 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. Step drills need to drill holes of different diameters as needed, and can process large holes at one time. Step drills can be used to drill holes in rock. In addition to being simple and compact, this tool also has the advantages of easy use, a flexible structure, 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. Unbreakable, extremely durable and adaptable. This drill bit ensures perfectly round holes by reducing the amount of thrust required when drilling a specific size.

Designed specifically for metal drilling, the double helical chip flutes and highly rounded back edges remove chips quickly to produce precise, clean holes. This drill is extremely durable and adaptable, and the straight shank design fits snugly and won't break easily. In addition to improving performance and efficiency, the rotary design increases drilling speed. Surface treatment prevents rust and wear. And the bit shank is marked for easy size identification.

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.
