The 19-piece HSS Cobalt Drill Bit Set from PTG offers an outstanding solution for precise drilling in various types of metal. The twist drills are made from high-quality cobalt-alloyed high-performance steel, which gives them a significantly longer lifespan compared to conventional HSS drill bits. With diameters ranging from 1.0 to 10.0 mm in 0.5 mm increments, this set covers a wide range of applications. The drill bits are specifically designed for use in unalloyed and alloyed steels, as well as stainless and acid-resistant steels. The gold-colored surface not only provides an appealing look but also contributes to the durability and resilience of the bits. This set is ideal for professional users who value quality and efficiency.
