DIN 1.3247 / M42 is a Cobalt-Molybdenum high speed steel according to DIN standard. The 1.3247 steel can reach high hardness of 70HRC after Quenching and Tempering. 1.3247 tool steel has good red hardness and high temperature hardness. Cutting tools made of 1.3247 steel can be used to cut high temperature iron base and casting alloys. This steel has poor toughness,so the quenching temperature should be low.
