Long drill bit for metal 8,6
High-quality ground long drill bit for metal fi 8 ,6 twist, with smooth cylindrical shank with a diameter of 8,6 mm, made according to the standards of the dimensional standard NWKb, DIN 340. It has 2 central blades, a tip angle of 118 degrees, strong cutting edges and spiral grooves for rapid discharge of chips up the drilled hole. The long metal drill bits we offer fi 8.6 are precision ground entirely from modern HSS high-speed steel. This is a steel that increases the cutting capabilities of the drill bits, and most importantly, allows them to work in very harsh conditions. Thanks to it, high-performance drilling at high speeds is possible. Even the high temperatures generated during such processing do not damage the drill bits. Their blades are resistant to breaking, cracking, chipping, chipping and other types of damage. In addition, the drills allow very accurate drilling. The holes made are axial along the entire length and are characterized by low roughness. The drills are designed for traditional drilling machines, lathes and milling machines, as well as for modern CNC computer-controlled automatic machining machines.
