The end ru00ecgida and method for producing uivia end ru00ecgida,The object of the invention is to provide a rigid end in the side of the tip has wear resistance and the connection side has a hardness; chemical composition of the alloy rigid sintered to constitute the rigid end is such that a ratio of composition of WC Co is sub Stancialmenre the same from the side of the tip to the connection side.And a first metal connections or a second metal connection has a chemical composition gradient, characterized by the fact that the contents of the first metal connection or second metal connection is increased from the side of the tip to the connection side, the first metal alloy. Tion does not form the eutectic texture with the toilet.And the second metal connection has the temperature eutectic with the toilet above the eutectic temperature of the alloy rigid su00ednteru00edzada of WC - CO and the melting point above the temperature of liquid phase sintering of WC Co hard alloy su00ednteru00edzada.
