Drill 20.5 cobalt with Morse fin

High-quality metal drill fi 20,5 cobalt with Morse taper shank for steel, type NWKc with dimensions: 20,5 mm, , apex angle of 118 degrees, 2 central blades and spiral grooves, the purpose of which is to quickly and effectively drain chips up the drilled hole. The 20.5 cobalt NWKc metal drill bits we offer are made in accordance with the dimensional standard DIN 345, from high-quality HSSE high-speed steel. The drills are designed for drilling holes in very hard materials, such as alloy steels, cast iron, cast steel, iron sinters, stainless steel, acid-resistant steel and others. NWKc drills made of HSSE steel are characterized by increased machining efficiency and also higher accuracy of drilled holes. They are resistant to abrasion and all mechanical damage, including breaking, cracking, blunting and chipping. NWKc drills are suitable for conventional drilling machines, lathes, milling machines and also for modern CNC numerical control machine tools.
