Grooving burr 9 two-point burr
Professional 9 two-flute groove burr, double-flute, NFPg with a nominal diameter of 9 mm, in accordance with DIN 327. It is a right-cutting cutter, mainly designed for groove cutting. It works well in both coarse and medium fine machining processes. The cutter is made according to the DIN 327 dimensional standard, from modern HSS (High Speed Steel). It has two central cylindrical-front blades with a 25-degree turning angle and a short shank for maximum rigidity of the tool. The NFPg milling cutters offered in our store are available in two versions: for smooth cylindrical shank DIN 1835 A (for collet holders) and for cylindrical shank with Weldon flattening DIN 1835 B, thanks to which it is possible to mount the shank with an additional screw to prevent the holder from rotating. Our 9 burrs are characterized by above-average hardness and durability, as well as greater resistance to possible mechanical damage.
