Classification: CPC B  F | IPC B  F

Claim 12:
13. The impact tool of claim 1,
wherein the gear train includes
a first planetary gear stage that receives torque from the motor, the first planetary gear stage including
a first sun gear configured as a motor pinion of the motor,
a rotationally fixed first ring gear,
a plurality of first planet gears encircling the first sun gear and rotatable about the first sun gear within the first ring gear, and
a first planet carrier coupled to the plurality of first planet gears, such that rotation of first planet gears about the first sun gear causes rotation of the first planet carrier,

a second planetary gear stage that receives torque from the first planetary gear stage, the second planetary gear stage including
a second sun gear coupled to the first planet carrier,
a rotationally fixed second ring gear,
a plurality of second planet gears encircling the second sun gear and rotatable about the second sun gear within the second ring gear, and
a second planet carrier coupled to the plurality of second planet gears, such that rotation of the second planet gears about the second sun gear causes rotation of the second planet carrier,

a first intermediate shaft that is coaxial with the motor axis and is coupled to the second planet carrier, the intermediate shaft including a first parallel axis gear, and
a second intermediate shaft that is parallel with the motor axis and includes a first bevel gear and a second parallel axis gear that is engaged with the first parallel axis gear, and

wherein the rotational input is configured as a second bevel gear that is engaged with the first bevel gear.
