Drill 3.9 mm on Morse taper with fin
Drill fi 3.9 mm with Morse taper shank for steel, complying with DIN 345, designed for machining materials classified as P1.2 - P1.3. This is a drill bit for unalloyed steel, metals, nonferrous metals, plastics and metal alloys. It has two central blades, strong cutting edges and also special grooves for fast chip removal up the drilled hole. The 3.9 metal drill bits of this type are manufactured from modern HSS (High Speed Steel), using the rolling method. Their advantages are increased hardness and durability, as well as resistance to abrasion under high temperatures. They can be used even in harsh conditions, without fear of mechanical damage to the blade. HSS drills are resistant to breakage, chipping, cracking and even rapid dulling. They are suitable for all conventional machine tools (drills, lathes, milling machines) as well as CNC numerical machines.
