The HSS step drill from the brand Alpen is a high-quality tool specifically designed for drilling cylindrical holes in metal. With a diameter ranging from 4.0 to 12.0 mm and a step angle of 90°, this drill allows for precise and clean drilling in materials up to 6 mm thick. The construction from high-speed steel (HSS) ensures high cutting performance and durability. The deeply ground and twisted flute guarantees smooth operation and minimizes vibrations during the drilling process. A special feature of this step drill is its ability to both drill and deburr, which increases efficiency during machining. The cylindrical shank with a diameter of 6 mm allows for easy handling and compatibility with common drills.
