Disclosed is a two-part piston ( 1 ) for a combustion engine comprising a combustion chamber ( 16 ) in the piston head ( 13 ). The piston ( 1 ) is composed of a basic member ( 5 ) and a top part ( 6 ) that is screwed to the basic member ( 5 ). In order for the combustion pressure to act substantially upon the basic member ( 5 ), which is provided with great mechanical stability and load-bearing capacity relative to the pressure prevailing in the combustion chamber, the bottom part of the combustion chamber ( 16 ) is molded into the basic member ( 5 ), the top part ( 6 ) is configured in an essentially annular manner, and the top part ( 6 ) enlarges the combustion chamber ( 16 ) at the piston head end while delimiting the same in a radially outward direction similar to a collar ( 19 ).
