The 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 specialised 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.
