Abstract: A grinder (100) includes a motor (12), a housing (4, 6, 30), a spindle (24), a first cover (120), and a second cover (170). The spindle protrudes downward from the housing, is driven by the motor, and thereby rotates. The first cover is provided in the circumferential direction of the spindle, is fixed to the housing, and at least partially covers a tool accessory (40), which is mounted on the spindle, from above. The second cover is detachably mounted on the housing (6) independently of the first cover.
