Abstract: A hand-held power tool 1 has a tool socket 2 to hold a tool 4 on a working axis 11, a motor 5 and a pneumatic striking mechanism 6. A driven shaft 7 is coupled to the tool socket 2 in order to rotate the tool around the working axis 11. A slip clutch 24 is arranged in the drive train between the motor 5 and the driven shaft 7. The slip clutch 24 has a disk 25 on the drive side and a disk 26 on the driven side. On a driving ring surface 28 that is in contact with the disk 26 on the driven side, the disk 25 on the drive side has first sectors 33 that have a high friction value as well as second sectors 34 that have a low friction value. On the driven ring surface 29 that is in contact with the driving ring surface 28, the disk 26 on the driven side has third sectors 35 that have a high friction value as well as fourth sectors 36 that have a low friction value.
