A solid carbide step drill is a cutting tool with multiple step-like cutting edges designed for drilling holes with different diameters in a single operation. It is constructed with a solid carbide material, ensuring high hardness, durability, and heat resistance. Solid carbide step drills provide precise and efficient drilling, reducing the need for multiple tool changes and saving time during machining processes. They are commonly used in industries like metalworking, woodworking, and fabrication for applications such as hole enlargement, countersinking, and chamfering.
