Drill fi 2.8 with cylindrical shank.
Drill 2.8 mm HSS. Highly professional cylindrical twist drill bit for drilling through-holes and blind holes in materials of the P1.2 - P1.3 class (metals, non-alloy steels, non-ferrous metals, metal alloys and plastics). The tools we offer have 2 central blades with strong cutting edges resistant to impact and lateral forces, as well as special chip grooves for the discharge of chips up the drilled hole. The cylindrical drills in our range are manufactured in accordance with the NWKa DIN 338 dimensional standard from high-alloy HSS. It is a steel with high cutting properties, which affect higher machining efficiency and also higher drilling accuracy. The holes are of low roughness. Drill 2.8 mm is resistant to harsh cutting conditions and resistant to mechanical damage (breaking, cracking, chipping, breaking out, dulling). The tools are also characterized by high resistance to high temperatures (up to 600 degrees) and also high hardness. They are designed for conventional drills, milling machines, lathes and computer numerical control machine tools - CNC.
