DEWALT HSS Cobalt Drill Bit:3.0mm - DIN 338

This is a DEWALT drill bit constructed from high-speed steel cobalt alloy, designed for durability and heat resistance during drilling operations. The tool adheres to the DIN 338 standard, ensuring reliable performance and consistent geometry for precision work. It features a nominal diameter of 3.0mm, making it suitable for creating medium-sized holes in tough materials where standard high-speed steel bits may wear out quickly. Buyers often select cobalt bits for their ability to maintain cutting edge integrity when machining hard steels, cast iron, or other difficult metals at higher speeds. To choose the correct size for your project, verify that the 3.0mm nominal diameter matches the required hole dimension for your specific application. Since the material composition is fixed as high-speed steel cobalt, no grade selection is necessary beyond confirming the metric size fits your workpiece.
