Long drill bit for metal fi 7,2
High-quality long drill bit for metal 7,2 cylindrical, twist, according to the dimensional standard NWKb, DIN 340. The drill bit is designed for professional drilling of through-holes and blind holes with a diameter of 7,2 mm in materials classified as P1.2 - P1.3. Long drill bit for metal 7,2 is suitable for drilling holes in metals, unalloyed steel, metal alloys, non-ferrous metals and other hard raw materials. The drills offered in our store have 2 central blades, a 118-degree tip angle, chip grooves that carry chips away from the drilled hole, and strong cutting edges that are insensitive to impact and lateral forces. Our drill bits are uniform, which means they are made entirely of special HSS high-speed steel. Its high cutting properties result in better drilling performance. The holes made are axial along the entire length and are characterized by low roughness. In addition, the drills make it possible to increase cutting efficiency and thus reduce machining time and make more rational use of workstations. They are suitable for conventional drills, milling machines, lathes and CNC machine tools.
