90° PM (powder metallurgical steel) countersinks according to DIN 335-C, cylindrical shank, robust design with 3 flutes. Due to CBN precision ground geometry very sharp and precise cutting edges.
Ideal for deburring or countersinking of high tensile steels (>1.000N/mm²) or high abbrasive materials like GG cast iron with a hardness of 240HB or more. Best results with low rpms!
Material groups : 1.1 - 1.6 / 2.1 - 2.3 / 3.1 - 3.3 / 5.1 - 5.4
