HSS-Co 8 Series Annular Cutters

Made in Germany

The made in Germany annular cutters from this series have outstanding heat resistance and wear protection. In combination with speed-controlled BDS magnetic core drilling machines, these annular cutters are suitable for machining fine-grained steels and rustproof materials. BDS recommends the BDS 5000 Cutting Oil for machining stainless steel. Cobalt 8% annular cutters are specialized cutting tools commonly used in metalworking and machining processes. The 8% cobalt content in these cutters refers to the percentage of cobalt present in the cutter's composition, which enhances their performance and durability compared to standard high-speed steel (HSS) cutters.

  • High degree of heat resistance
  • Better wear protection
  • High cobalt content of 8%
  • Suitable for higher loads in fine-grained steels and rustproof materials
  • With 19 mm or 32 mm Weldon shank
  • Can be resharpened
The goal of this latest BDS product development was a performance-optimized core drill series with higher heat resistance and better wear protection. An increased cobalt content in special steel brought the desired results. In conjunction with speed-controlled BDS magnetic core drilling machines, these core drills are suitable for higher loads in fine-grained steels and stainless materials. The core drills can be reground, they retain their positive product properties.
