Long drill bit for metal 7,8
High-quality long drill bit for metal 7,8 with smooth cylindrical shank, made according to NWKb, DIN 340 standard. It is a professional drill bit intended for professional drilling works carried out in large workshops and locksmith's workshops with the use of conventional drills, lathes and milling machines, as well as modern computer numerical control machine tools in CNC technology. These long metal drills 7,8 are characterized by high cutting parameters, which are due to the use of modern high-speed steel HSS (High Speed Stell) for their production. Its properties have an impact on higher drilling efficiency, thus resulting in shorter working time and more rational use of owned machining stations. In addition, high-speed steel drills are very resistant to harsh working conditions, and their blades are resistant to fracture, cracking, chipping, breaking out, which significantly extends the period of their use.
