Long drill bit for metal fi 20
Professional long drill bit for metal fi 20 cylindrical with a diameter of 20 mm for drilling through-holes and blind holes in very hard and hard-to-machine materials. Long drills for metal fi 20 are made according to the dimensional standard NWKb, DIN 340 from special molybdenum high-speed steel HSS - High Speed Steel. This is a modern tool steel, which affects the possibility of obtaining much higher cutting properties. First of all, drills made of this steel are more resistant to severe cutting conditions and resistant to mechanical damage than drills made of conventional tool steel. The drills in our store allow you to achieve high machining efficiency and thus reduce working time and make better use of your machine tools. They can be used to drill holes in parts made of unalloyed steel, metals, copper, aluminum, bronze, brass and others. They are suitable for various types of drilling machines, lathes and milling machines, as well as modern CNC - computer numerical control machine tools.
