Abstract
A screw connection to be undone without problems and without disproportionate application of force after long-term use in cutting under extreme usage conditions with dirt, extreme heat, moisture, oxidation and alternating loads provides that the screws have a smooth surface due to coating at least in the area of the thread of the screws, that PTFE particles, preferably have a particle size between 100 nm and 300 nm, are continued in the coating, and the screw connection of the two thread partners are lubricated using small amounts of a heat-resistant grease having ceramic powder particles.

1-17. (canceled)
A screw connection having a screw and an associated threaded hole on a cutting tool, wherein the screw has a smooth surface that is coated in at least the area of thread, wherein the coating comprises PTFE particles, and the screw connection is lubricated with a heat-resistant grease comprising ceramic powder particles.
A method for improving a screw connection having a screw with a thread and an associated threaded hole on a cutting tool, comprising coating the screw in at least in the area of the thread in order to obtain a smooth surface, wherein PTFE particles are incorporated into the coating, and wherein the screw connection is lubricated with small amounts of a heat-resistant grease containing ceramic powder particles.
A cutting tool comprising a screw connection coated at least in the threaded area and which contain PTFE particles in the coating, in screw connections on a cutting tool, wherein the screw connection forms at least a portion of a clamping claw.
A cutting tool comprising a cutting element, a screw connection comprising a screw and a hole for receiving said screw, wherein the screw is threaded and the hole has receiving threads for receiving the threads of the screw, wherein said screw connection is lubricated on the threads of the screw and the receiving threads of a corresponding hole for receiving the screw with grease, wherein the screw is coated with a coating that comprises PTFE particles, wherein the thread partners of the screw connection is lubricated with a heat-resistant grease containing ceramic powder components.
A screw coated with a coating having PTFE particles incorporated therein.
A grease for lubricating screw connections on cutting tools, wherein the grease is heat-resistant and is provided with ceramic powder components.
