The invention relates to a reamer R comprising a base body ( 1 ) with a cutting element ( 2 ) and at least one guiding strip ( 3 ) aligned essentially axially with an abutment surface ( 31 ) and a guiding surface ( 32 ), whereby the guiding strip ( 3 ) is connected to the base body ( 1 ) in the area of the abutment surface ( 31 ). In order to be able to work different materials with a single reamer R over a long period of use of the reamer R, it is proposed according to the invention that the guiding strip ( 3 ) is formed of layered bodies ( 41, 42 ) with different materials running from the guiding surface ( 32 ) to the abutment surface ( 31 ). |
