The present invention relates to a cemented carbide with a homogeneous and dense microstructure of hard constituents in a well distributed binder phase based on Co and/or Ni with a porosity of A00-B00according to ISO 4505. The cemented carbide has a nanoporosity of less than 2.5 pores/1000 [mu]m2 with a size of 0.5-1 [mu]m. The cemented carbide is produced by using a binder phase powder with a specific surface area of 3 to 8 m2/g with a sponge shape and a grain size of the sponge shaped particles of between 1 and 5 [mu]m.
