Long drill bit for metal fi 4

Long drill bit for metalfi 4 complies with NWKb, DIN 340. Designed for professional processing of very hard and hard-to-machine materials classified as P1.2 - P1.3. These include metals, unalloyed steels, non-ferrous metals, metal alloys and plastics. Long metal drills fi 4.0 of this type have 2 central blades, strong ground cutting edges that are insensitive to lateral forces and impacts, as well as spiral grooves responsible for fast chip removal up the drilled hole. These are uniform drills, made entirely by grinding from modern HSS high-speed steel. The steel's advantages contribute to better drilling results. First of all, they allow high-performance drilling at high speeds. They also make it possible to work in very tough conditions without compromising high cutting precision. They are suitable for machining unalloyed steel, metals, metal alloys, nonferrous metals and plastics. They can be used with conventional drills, lathes and milling machines as well as modern CNC machine tools.
