Description
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. Technical specifications: • Type: Step drill bit • Material: HSS high-speed steel • Coating: TiAlN (titanium aluminum nitride) • Shank: Cylindrical • Drilling diameters (mm): 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52 • Step increment: every 4 mm • Total length: 104 mm • Working length: 80 mm
