摘要: A sander includes an airflow element rotatable about a central axis along a preset direction of rotation to generate a dust removal airflow; an electric motor for providing a power source for the airflow element; and a battery pack for providing an energy source for the electric motor. When the sander is in a load-free state, the working duration of the sander when the battery pack consumes 10 WH of energy is defined as the functional time T of the sander; and the product of the load-free rotational speed N of the electric motor and the functional time T of the sander is greater than or equal to 63000 rpm·min and less than or equal to 120000 rpm·min.

摘要: A power tool has a motor, an output shaft, a spindle, a gear, a gear housing and a bearing. The spindle is configured to be rotated around a drive axis crossing an extending direction of the output shaft. The gear is fitted on the spindle and configured to transmit rotation of the output shaft to the spindle. The gear housing houses the spindle, the gear and the bearing with the lower end part of the spindle protruded downward. The bearing is arranged on the radially outer side of the gear and configured to support the spindle so as to be rotatable around the drive axis.
