a housing configured to mount a dust collection attachment;
an impact mechanism unit (i) inside the housing, (ii) having (a) a front end configured to receive and retain a tool bit and (b) an impact element that reciprocates, and (iii) being configured to impact the tool bit by the impact element when the tool bit is retained by the front end;
a motor having a rotation shaft that intersects an impact axis direction of the impact mechanism unit inside the housing;
a dust collection fan on the rotation shaft; and
a motor cooling fan (i) on the rotation shaft and (ii) adjacent to the dust collection fan in an axial direction of the rotation shaft; wherein
the motor cooling fan is integrally formed on an upper side of the dust collection fan with a partition plate having a circular shape in plan view as a boundary,
