Honing tool for honing blind bores

Abstract

The invention relates to a honing tool ( 1 ) that is suitable in particular for honing blind bores ( 5 ), comprising a stone carrier ( 3 ), a first honing stone segment ( 16 ) and a second honing stone segment ( 17 ). The first honing stone segment ( 16 ) and the second honing stone segment ( 17 ) are fastened in a groove ( 22 ) of the stone carrier ( 3 ). In addition, the stone carrier ( 3 ) comprises an end ( 10 ) with which the stone carrier ( 3 ) can be introduced into a bore ( 5 ). The second honing stone segment ( 17 ) is fastened closer to the end ( 10 ) of the stone carrier ( 3 ) than the first honing stone segment ( 16 ). Moreover, the wear resistance of the second honing stone segment ( 17 ) is greater than a wear resistance of the first honing stone segment ( 16 ). In this way, a straight bore ( 5 ) can be honed even in the case of limited idle travel ( 9 ).
