Abstract: A grinder includes a motor, a housing, a spindle and a cover. The spindle protrudes downward from the housing, is driven by the motor, and thereby rotates. The cover at least partially covers a tool accessory mounted on the spindle. The cover includes a first cover part and a second cover part. The first cover part is fixed to the housing and at least partially covers the tool accessory from above. The second cover part is held such that it is capable of moving relative to the first cover part. The grinder is configured such that the area of the tool accessory covered by the cover changes in accordance with the relative movement.

Abstract: A cover may be used in a tool with a tip tool. The cover may include an inner cover covering at least a part of the tip tool and an outer cover covering at least a part of the inner cover. In the cover, a space between the inner cover and the outer cover may constitute a suction path through which suctioned air flows. In the cover, a shape of the suction path may be changeable by a change in a relative positional relationship between the inner cover and the outer cover.

Abstract: A tool includes a prime mover, switch, operation member for the switch, first accessory, second accessory, third intermediate member moved in conjunction with displacement of the operation member, first intermediate member configured to be displaced from a first blocking position of blocking a displacement route of the third intermediate member to a first non-blocking position of not blocking the displacement route by attachment of the first accessory, and second intermediate member configured to be displaced from a second blocking position of blocking the displacement route to a second non-blocking position of not blocking the displacement route by attachment of the second accessory. Only when the first intermediate member is located at the first non-blocking position and the second intermediate member is located at the second non-blocking position, the third intermediate member is permitted to be displaced so that the operation member is permitted to be displaced to the ON position.
