Abstract: A power tool includes a motor with a motor output shaft, a spindle driven by the motor output shaft to rotate about an axis, and a clutch mechanism positioned between the motor and a distal end of the spindle. The clutch mechanism is to execute a clutching event to limit an amount of torque transmitted from the motor output shaft to the spindle when the torque reaches a torque threshold. The power tool further includes a sensor that detects an acceleration of the power tool and a controller. The controller is to control a speed of the motor, obtain acceleration inputs from the sensor, detect the clutch mechanism executing the clutching event using the acceleration inputs, a power of the motor, and the speed of the motor, and reduce the speed of the motor when the clutching event is detected.
