Abstract
A power tool performs a predetermined operation by using a tool bit and has a grip part and a dust suction device. The dust suction device has a dust suction part that extends in an axial direction of the tool bit and sucks and collects dust generated during operation at a tip of the tool bit. The dust suction part can be moved between a first position in which the dust suction part covers a bit tip of the tool bit and a second position in which the bit tip is exposed. The dust suction device further has an operation mode switching mechanism that is capable of switching between a first operation mode in which the dust suction part is allowed to move between the first and second positions and a second operation mode in which the dust suction part is locked in the second position.
