Drill cobalt 4,5 Inox
Drill 4,5 mm cobalt HSSE Inox. Professional twist drill, with smooth cylindrical chuck for drilling through-holes and blind holes with a diameter of 4.5 mm. The drill has 2 central blades, special grooves for fast chip removal up the drilled hole, and strong ground edges insensitive to impact and lateral forces. The cylindrical drills we offer are made according to the recommendations of the , DIN 338 dimensional standard from special cobalt HSS-E high-speed steel. It is a steel that affects a significant increase in machining efficiency, thereby reducing drilling time and better use of the workstations. They make it possible to drill very accurately, and the holes made are of low roughness. In addition, high-speed steel with the addition of 5% cobalt affects the greater strength of the drill bits to withstand harsh working conditions and thus increase their resistance to mechanical damage such as fractures, cracks, chipping, dulling. Drill 4.5 mm cobalt is suitable for conventional and CNC-controlled machine tools.
