Amazing device to cut metal with high precision

Plan / Templates - https://jisaku-koubou.com/downloads/plansemi-automatic-grinder-cutter I made a semi-automatic grinder cutter. When the switch is turned on, the motor rotates to move the grinder, and when the disconnection is completed, the movement stops. For safety, the grinder body is turned on and off manually. In addition, since the grinder body can be easily attached and detached, it can be used as it is as a hand tool.
