The objective of this most recent product development at BDS was to produce a range of annular cutters optimised for power with greater heat resistance and better protection against wear. The desired results were achieved by an enhanced proportion of cobalt in special steel. Combined with speed-controlled BDS magnetic drilling machines, these annular cutters are adapted for high loads in fine-grained steels and rust-proof materials. The annular cutters can be reground whilst retaining their positive product characteristics.
The drills of this series are characterised by high thermal resistance and wear protection. In combination with speed-controlled BDS magnetic annular cutter ing machines, they are suited for the processing of fine-grain steel and stainless materials. For the processing of stainless steel, BDS recommends the cutting oil BDS 5000.
