T-slot arbor cutter 21 2 flute
Modern burr 21 2 flute for keyway grooving, double-edged, NFPg in accordance with dimensional standard DIN 327. Designed for keyway grooving and other milling work. It is recommended for medium fine and coarse milling. It is suitable for machining hard unalloyed steels, alloyed steels, various grades of cast iron, metals, non-ferrous metals and their alloys. It is made according to the latest standards from special HSS (High Speed Steel). Thanks to this steel, the cutters are harder and more durable than cutters made of conventional tool steel. The 21 burrs also feature better cutting properties and greater resistance to any mechanical damage. This allows for a significant increase in service life and thus a reduction in overall machining costs. NFPg milling cutters are suitable for conventional machine tools and modern CNC computer-controlled automatic machines.
