A cold press and a method for the production of green compacts for diamond-containing tool segments includes a tool matrix, a top ram and a bottom ram assigned to a matrix adapter from opposite directions for the purpose of compressing sinterable metal powder and diamond granules after both of these materials have been fed to the matrix adapter. Step-by-step build-up of the green compact is carried out in such a manner that after one layer of metal powder and one layer of diamond granulate have been charged, these layers are together compressed.
