Modern long drill bit for metal fi 4,1 twist with a diameter of 4,1 mm. It has a special geometric design affecting a better drilling process. The drill's strong cutting edges are insensitive to impact and lateral forces, and special chip grooves allow fast removal of chips from the drilled hole. The long metal drill fi 4.1 also has 2 central blades and a tip angle of 118 degrees, which improves machining results.
