Features
- The HSS spiral drill bit cobalt lasts a long time when drilling into stainless steel
- This extended service life is due to the steel alloy containing 5% cobalt and the fully ground HSS (High-Speed Steel), which offers excellent surface quality, wear resistance and heat resistance
- Thanks to two cutting edges and two grooves, chips are removed quickly, increasing the lifetime of the drill bit
- This drill is suitable for alloyed and unalloyed steel, stainless steel, cast iron and acid and heat resistant steel
- The HSS spiral drill bit cobalt is produced according to DIN 338
- The drill is of type N (groove angle) with a point of 135 degrees and a diameter tolerance of h8
- The pointed cleft point provides an active cutting action and perfect centring without slipping
- This drill is suitable for alloyed and unalloyed steel, stainless steel, cast iron and acid and heat resistant steel
- The drill has a cylindrical shank (drill and shank have the same diameter) and is intended for use in drill stands and drilling/screwing machines
