Power tool and a transmission therefor

A power tool comprising:

• a motor having a drive shaft that rotates about a motor rotation axis;
• and
• a transmission having an intermediate shaft with a first rotation axis operatively coupled to an output shaft with a second rotation axis connected to a tool holder and the intermediate shaft is operatively coupled to the drive shaft via an input shaft having a third rotation axis that is offset from the motor rotation axis, wherein the output shaft comprises at least a first gear and a second gear, the intermediate shaft comprises at least a first idling gear and a second idling gear configured to respectively engage the first gear and the second gear such that the transmission is configured to transmit torque from the motor to the tool holder via a first gearing or a second gearing, and the input shaft comprises a clutch that disengages the motor from the transmission when a predetermined torque threshold is exceeded,
• wherein each of the first rotation axis, the second rotation axis and the third rotation axis are offset from each other in a first direction and a second direction.

• and
• a gear selection mechanism moveable within the output shaft and configured to selectively engage the first gear or the second gear,
• wherein each of the first rotation axis, the second rotation axis and the third rotation axis are offset from each other in a first direction and a second direction,
• wherein the first direction and the second direction are perpendicular to each other,
• wherein a first plane defined by the first direction and the second direction is perpendicular to the first rotation axis, and
• wherein the first gear overlaps at least a portion of the second idling gear.
