Abstract: A power tool having a rotary hammer mechanism is configured to produce hammering motion for driving a tool accessory along a driving axis and rotating motion for rotating the tool accessory around the driving axis. The power tool has a tool holder that is configured to removably hold the tool accessory. The tool holder has a rotation transmitting part configured to transmit rotating power to the tool accessory. A layer formed of carbide of a group 5 element of a periodic table is formed on the rotation transmitting part.

Abstract: A power tool, such as a grinder, may include: a prime mover such as a motor; a power-transmission mechanism operably connected to the prime mover; a housing that houses the prime mover and the power-transmission mechanism; and a tool-accessory retaining part for holding a tool accessary. The tool-accessory retaining part is operably connected to the power-transmission mechanism. An accessory is mounted on the housing in a detachable manner. A link member moves in response to mounting and demounting of the accessory. A detection sensor is housed in an interior of the housing and includes a non-contact sensor device. The detection sensor is configured to detect movement of the link member using the non-contact sensor device.

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.
