Abstract
A hard-material threaded connection includes a structural part, which has a hard material and a first threaded portion formed in the hard material, and a component having higher elasticity that has a second threaded portion cooperating with the first threaded portion. The first threaded portion and the second threaded portion have a different thread pitch.

1-15. (canceled)
A hard-material threaded connection, comprising:
- a structural part having a hard material and a first threaded portion formed in said hard material;
- and
- a component having higher elasticity than said hard material and having a second threaded portion cooperating with said first threaded portion, said first threaded portion and said second threaded portion having different thread pitches.
A method for forming a threaded connection between a hard material and a component a having higher elasticity than the hard material, which comprises the steps of:
- screwing a structural part having the hard material and a first threaded portion formed in the hard material, to the component having the higher elasticity, the component having a second threaded portion cooperating with the first threaded portion, thereby forming the threaded connection, the first threaded portion and the second threaded portion have different thread pitches.
The method according to 27, which further comprises forming the second threaded portion as a standard thread and the first threaded portion with a thread pitch deviating from the standard thread.
A structural part, comprising:
- a hard material having a first threaded portion formed therein, the first thread portion configured for connecting to a second threaded portion formed on a component having a higher elasticity than said hard material, said first threaded portion having a thread pitch deviating from the second threaded portion.
A method of forming a tool having a hard-material threaded connection, which comprises the steps of:
- providing a tool body;
- providing an exchangeable cutter;
- forming a hard-material threaded connection for connecting the tool body to the exchangeable cutter by performing the further steps of:
- forming at least a structural part of the exchangeable cutter from a hard material and having a first threaded portion formed in the hard material;
- forming a component of the tool body with a higher elasticity than the hard material and having a second threaded portion cooperating with the first threaded portion formed in the hard material, the first threaded portion and the second threaded portion having different thread pitches;
- and
- connecting the exchangeable cutter to the tool body by threading the first and second threaded portions to each other.
