Step Drill Bit 4–52 mm, GEKO

Step drill bit designed for drilling non-ferrous metals, steel sheets, and plastics.
Made of high-speed steel (HSS) for increased cutting efficiency and wear resistance. Coated with TiAlN (titanium aluminum nitride).

TiAlN-coated drill bits are particularly suited for drilling hard-to-machine materials, especially in conditions where coolant cannot be used or is limited. This coating significantly enhances wear resistance and allows for higher cutting speeds.
