Ø4.5 Inox cobalt drill bit for metal
4.5 mm cobalt drill bit for metal HSSE Inox. A professional twist drill with a plain straight shank for drilling through and blind holes with a diameter of 4.5 mm. The drill features 2 central cutting edges, special flutes for rapid chip evacuation up the hole being drilled, and strong ground cutting edges resistant to impacts and lateral forces. The straight-shank drills we offer are manufactured in accordance with the recommendations of dimensional standard NWKa, DIN 338 from special HSS-E cobalt high-speed steel. This steel significantly increases machining productivity, reducing drilling time and improving the utilization of available workstations. The drills enable very accurate drilling, and the resulting holes have low surface roughness. In addition, high-speed steel with 5% cobalt increases the drills' ability to withstand demanding operating conditions, thereby improving their resistance to mechanical damage such as breakage, cracking, chipping and dulling. 4.5 mm cobalt drill bit for metal is suitable for conventional and CNC machine tools.
