Cuttig edges drilling speed was able to be increased through optimisation of the cutting edges. The result is a strong cutting effect during the drilling process, allowing for a significantly higher feed rate. Therefore, the point contact of cutting on the material serves exclusively the running of the drill, whereby it becomes more stable. Large chip-free zones ensure perfect chip discharge. Forged version increased resistance. Shank with 3 flats prevents sliding through of the drill and ensures a long service life. Modular system extension. Characteristics DIN 7483G, with a small center point, 2 peripheral cutting edges, 2 lifters and reduced cylindrical shank, in premium quality. Other diameters and specifications on request. Usage for drilling splinter-free, true to size blind holes, for edge drillings and slant drillings in softwood and hardwood. Easy and effortless cutting due to ideal cutting geometries. The drilling speed was able to be increased through optimisation of the cutting edges. The BLACK SHARK is even quicker, more aggressive and sharper than all other forstner drill bits worldwide.
