Abstract: A handheld power tool includes a housing, a tool receptacle disposed on a first end of the housing and configured to receive a tool accessory, a motor positioned within the housing and operatively coupled to the tool receptacle to drive the tool accessory, and a dust collection assembly integrated within the housing. The dust collection assembly includes a fan disposed within the housing and operatively coupled to the motor. The fan is configured to generate a suction airflow due to rotation of the motor, and a dust container removably coupled to the housing of the power tool. The dust container is configured to collect dust and other debris generated by the tool accessory during operation of the handheld power tool.
