摘要: A drill bit which is rotatable about a drilling axis is disclosed. The drill bit has a cutting section having one or more cutting segments and a first plug-connecting element and a drill shaft section having a second plug-connecting element. The first plug-connecting element and the second plug-connecting element form a plug connection and the first plug-connecting element and the second plug-connecting element are connectable by a pin connection.

摘要: A drill bit which is rotatable about a drilling axis is disclosed. The drill bit has a drill shaft section having a first plug-connecting element and a cutting section having a second plug-connecting element. The first plug-connecting element and the second plug-connecting element form a plug connection. The cutting section includes a plurality of cutting subsections each having a ring subsection and at least one cutting segment, wherein each ring subsection together with the first plug-connecting element forms the plug connection and is connectable to the first plug-connecting element by a pin connection.
