Product Material<\/h4>\n

The SDF-A series drill is manufactured from solid tungsten carbide, renowned for its exceptional hardness, superior wear resistance, and compressive strength. Compared to high-speed steel, tungsten carbide exhibits higher heat resistance, maintaining its geometric shape and cutting performance even at elevated temperatures, making it ideal for machining high-hardness materials such as cast iron and steel. Additionally, tungsten carbide offers excellent chemical stability, minimizing reactions with the workpiece material and reducing tool wear.<\/p>\n
