Abstract: A power tool includes a spindle, a housing, a cover body configured to be removably mounted to the housing, a first engagement part provided on or in the cover body, and a second engagement part provided on or in the housing. The cover body includes an upper plate part and an outer peripheral part. The second engagement part is movable between an engagement position and a disengagement position. The first and second engagement parts are configured to restrict rotation of the cover body around the drive axis relative to the housing by engaging with each other. The first engagement part is (i) at a same location as or radially outward of the outer peripheral part of the cover body in a radial direction orthogonal to the drive axis, and (ii) between an upper end and a lower end of the cover body in the up-down direction.

Abstract: To avoid prolonged operation time at construction sites, an attachment includes an input shaft rotatable about a first rotation axis to receive power input from a power tool, a tip socket including a recess having a socket opening, a housing having a housing opening to receive a workpiece and supporting the tip socket in a rotatable manner, a power transmission that transmits, to the tip socket, power input into the input shaft, and a front aligner that stops rotation of the tip socket with the socket opening being aligned with the housing opening.
