The Made in Germany HSS Cobalt 8% annular cutters are made of special steel HSS M42 with a percentage of cobalt for greater heat resistance and wear protection M42 is a molybdenum-series high-speed steel alloy with an additional 8% cobalt It is widely used in metal manufacturing industries because of its superior red-hardness as compared to more conventional high-speed steels allowing for shorter cycle times in production environments due to higher cutting speeds or from the increase in time between tool changes M42 is also less prone to chipping when used for interrupted cuts and costs less when compared to the same tool made of carbide Tools made from cobalt-bearing high speed steels can often be identified by the letters HSS-Co
The BDS TCT annular cutters series with cutting depths of 30 mm, 35 mm, 55 mm, 75 mm and 110 mm and almost gapless range of diameters from 14 mm to 150 mm. For the processing of stainless steel and non-ferrous metals, BDS recommends the high-performance cooling lubricant concentrate BDS 6000.
BDS being the worlds' leading manufacturer has in its product range more than 21 types of magnetic drill press dedicated to core drilling, twist drilling, tapping, reaming and countersink. BDS also manufacturers special drilling machines such as cordless magnetic drilling machines, two types of rail drilling machines, pneumatic drilling machines, compact drilling machines, automatic drilling machines, cross table base drilling machines, etc.
