The fracture toughness of a number of cemented carbide alloys have been determined; using a wedge-impact method for precracking. The materials were of WC-Co type with cobalt content ranging from 6 to 25 wt-% and mean carbide grain size between 1.0 and 3.3 pm. Within the investigated composition rang
