Drill fi 17,25 with cylindrical shank

Drill 17.25 mm HSS. High-quality twist drill with cylindrical shank in accordance with the dimensional standard NWKa, DIN 338. It is a drill bit designed for all professional drilling work using conventional lathe and milling machines, as well as modern CNC-controlled machine tools. The drills offered in our store are distinguished by their high cutting parameters. This is due to the use of modern HSS (High Speed Stell) for their production. This type of tool steel influences the higher efficiency of machining, thus also shortening the machining time and more rational use of the workstations. Moreover, 17.0 mmmetal drill bits made of HSS are more resistant to harsh working conditions than drill bits made of conventional tool steel. First of all, their blades are resistant to breaking, cracking, chipping, breaking out, which significantly extends the period of their use.
