Hand-held power tool with a clutch and method for producing a groove in the circumferential wall of a clutch drum of a hand-held power tool

A hand-held power tool comprising:

• a drive motor;
• a clutch connected to the drive motor, wherein the drive motor drives a tool member through the clutch;
• the clutch comprising a clutch drum and the clutch drum comprising a circumferential wall provided with an end face;
• a follower member engaging a groove provided in the circumferential wall of the clutch drum, the groove extending from the end face of the circumferential wall into the circumferential wall and comprising a groove bottom and two groove sides positioned opposite each other;
• a driven element that is connected to the follower member to be driven by the follower member;
• wherein the circumferential wall comprises a protrusion located at the groove bottom, wherein the protrusion has a protrusion thickness measured at the groove bottom that amounts to at least approximately 110% of a wall thickness of the circumferential wall measured at the two groove sides;
• a brake device comprising a brake belt, wherein the brake belt interacts for braking with an outer side of the circumferential wall.

A method for producing a groove in a circumferential wall of a clutch drum of a clutch of a hand-held power tool, the hand-held power tool comprising:

• a drive motor;
• a clutch connected to the drive motor, wherein the drive motor drives a tool member through the clutch and the clutch comprises a clutch drum and the clutch drum comprises a circumferential wall provided with an end face;
• a follower member engaging a groove provided in the circumferential wall of the clutch drum, wherein the groove extends from the end face of the circumferential wall into the circumferential wall and comprises a groove bottom and two groove sides positioned opposite each other;
• a driven element that is connected to the follower member to be driven by the follower member;
• wherein the circumferential wall comprises a protrusion located at the groove bottom, wherein the protrusion has a protrusion thickness measured at the groove bottom that amounts to at least approximately 110% of a wall thickness of the circumferential wall measured at the two groove sides;
• the method comprising:
• die cutting a groove with a die-cut groove depth that amounts to approximately 75% up to approximately 95% of a nominal groove depth of the groove and with a die-cut groove width that amounts to approximately 50% up to approximately 110% of a nominal groove width of the groove;
• and
• subsequently plastically deforming a groove bottom of the die-cut groove until the nominal groove depth is reached.
