Long drill bit for metal 4,5
Modern long drill for metal 4,5 with cylindrical shank, made of special molybdenum HSS (High Speed Steel), in accordance with the dimensional standard NWKb, DIN 340. The drills we offer have strong ground cutting edges insensitive to impact and lateral forces, a tip angle of 118 degrees, and spiral chip grooves designed to carry chips up the drilled hole. The advantages of long drills for metal 4.5 cylindrical make them extremely resistant to very difficult working conditions, and above all to the high temperature created when cutting at high speed. Such drilling makes it possible to reduce the processing time and thus gives the possibility of better use of the available workstations. An important advantage of drill bits is their very long service life, which is closely related to the high resistance of high-speed steel to any mechanical damage, such as fractures, cracks, chipping, breakage, blunting and others. The drills are recommended for conventional drilling machines, lathes, milling machines and CNC numerical control machine tools.
