Burr 4 long two-flute cutter
A modern 4 long two-hole groove burr, double-edged, NFPg, arbor, right-hand cutter, type NFPg with a diameter of 4 mm, long. It conforms to the standards of the DIN 327 dimensional standard and is made entirely of special HSS (High Speed Steel). Thanks to this steel, the cutters are very hard and characterized by above-average resistance to very difficult cutting conditions. They can be used for machining hard and hard-to-machine materials of the P1.2 class - P1.3. This includes alloyed and unalloyed steels, gray, ductile and malleable cast iron, aluminum, copper, non-ferrous alloys and plastics, among others. The 4-long double-feather burrs offered in our store are dedicated to both individual customers and large industrial plants. They can be used for making keyways and other milling jobs using both conventional machine tools and modern CNC (computerized numerical control) machine tools.
