A grinder includes a brake mechanism, a switch lever, and a slide bar. In the grinder, an interlocking mechanism configured to interlock the brake mechanism with the switch lever includes a link member that is interposed between the switch lever and the slide bar, that moves the slide bar to the forward position at the push-in position of the switch lever, and that moves the slide bar to the retraction position at the initial position of the switch lever.

A grinder includes a brake mechanism configured to brake a spindle and an electrical actuator (a solenoid) that actuates the brake mechanism. The solenoid actuates the brake mechanism in conjunction with a turning OFF of a switch from a driving state of a motor, and releases an actuation of the brake mechanism after a lapse of a predetermined period of time from the turning OFF of the switch.
