The invention discloses a power tool which comprises a shell, a power source arranged in the shell, a fan connected with the power source and a tubular chip removal valve arranged on the shell; a reversing plate is arranged in the chip removal valve, air inlets are arranged on the tube walls of the chip removal valve at the two sides of the reversing plate, the airflow generated by rotation of the fan enters the chip removal valve from the air inlets, a splitter plate is arranged on the reversing plate near the air inlets, the splitter plate divides the airflow entering the chip removal valve into at least two parts, one part of the airflow is used for reversing the chip entering the chip removal valve, and another part of the airflow is used for blowing chip, therefore, the chip does not accumulate in the chip removal valve, chip removal is thorough and chip removal efficiency is high, and the power tool is not easy to be blocked by the chip in the process of operation.
