Abstract
A power tool includes a housing, a drive mechanism supported within the housing, a spindle operatively coupled to an output of the drive mechanism such that torque from the drive mechanism rotates the spindle about an axis, and an accessory removably coupled to the housing. The drive mechanism is configured to supply up to a first maximum torque to the spindle when the accessory is removed from the housing. The drive mechanism is configured to supply up to a second maximum torque to the spindle greater than the first maximum torque when the accessory is coupled to the housing.
Claims20
A power tool comprising:
- a housing;
- a drive mechanism supported within the housing;
- a spindle operatively coupled to an output of the drive mechanism such that torque from the drive mechanism rotates the spindle about an axis;
- an auxiliary handle removably coupled to the housing and having a length adjustable between a retracted length and an extended length;
- a sensor supported by the auxiliary handle;
- and
- a controller in communication with the sensor, the controller configured to determine if the auxiliary handle is set to the retracted length or the extended length based on feedback from the sensor,
- wherein the controller is configured to control the drive mechanism to adjust a maximum output torque of the drive mechanism based on the length of the auxiliary handle.
A power tool comprising:
- a housing;
- a drive mechanism supported within the housing and including a shiftable gear;
- a spindle operatively coupled to an output of the drive mechanism such that torque from the drive mechanism rotates the spindle about an axis;
- and
- an accessory removably coupled to the housing,
- wherein the accessory includes a portion configured to engage the shiftable gear to move the shiftable gear from a first position to a second position in response to the accessory being coupled to the housing.
A power tool comprising:
- a housing;
- a drive mechanism supported within the housing;
- a spindle operatively coupled to an output of the drive mechanism such that torque from the drive mechanism rotates the spindle about an axis;
- an auxiliary handle removably coupled to the housing and including a sensor;
- a controller configured to control an operating direction of the drive mechanism based on input from the sensor.
