Long drill bit for metal fi 3,9
Specialized long drill bit for metal fi 3,9 cylindrical with a diameter of 3,9 mm entirely made of modern HSS high-speed steel. It has strong ground cutting edges that make it insensitive to impact and lateral forces. Special spiral grooves allow fast removal of chips from the drilled hole, and the tip angle of 118 degrees guarantees very aggressive drilling in very hard materials falling into the category P1.2 - P1.3 (metals, unalloyed steels, non-ferrous metals, metal alloys, plastics). Long drills for metal fi 3,9 found in our store are resistant to harsh cutting conditions, including the high temperature created when drilling at high speed. Their blades are resistant to mechanical damage, which significantly extends their service life. The drills can be used with various types of conventional drilling machines, lathes and milling machines, as well as CNC-controlled machine tools.
