Power tool with a torque clutch

A power tool comprising:

• a handle configured to be gripped by a user;
• a driving section configured to generate rotational driving force selectively in a forward direction and in a reverse direction and including an output shaft that outputs the rotational driving force;
• an end-bit mounting section configured to hold an end bit and to be rotatable about a rotational axis extending in an axial direction;
• and
• a friction clutch provided between the end-bit mounting section and the driving section and serving as a first clutch movable between a transmission position and a cutoff position, the friction clutch comprising:
• a drive member driven by the driving section and including a drive-side contact surface;
• and
• a follow member including a follow-side contact surface that is capable of contacting the drive-side contact surface and slidingly movable relative to the drive-side contact surface to generate a frictional force therebeween when the end-bit mounting section moves toward the driving section in the axial direction;
• and
• a second clutch provided between the end-bit mounting section and the driving section,
• wherein the user gripping the handle and pressing the end bit against a workpiece moves the end-bit mounting section toward the driving section in the axial direction and generates a torque transmitted to the end bit mounting section by the friction clutch,
• wherein the torque transmitted to the end bit mounting section by the frictional clutch is generated only by frictional force,
• wherein, when the first clutch is at the transmission position, the rotational driving force of the driving section at least in the forward direction can be transmitted to the end-bit mounting section,
• wherein, when the first clutch is at the cutoff position, the rotational driving force of the driving section through the first clutch is cut off before the end-bit mounting section, and
• wherein the second clutch is configured to transmit the rotational driving force of the driving section only in the reverse direction to the end-bit mounting section via a different route from the first clutch.
