When working with a dremel, precision is required, as this device is often used with small objects. The depth stop makes it possible not to pierce a through hole in the material you are working with. The nozzle is put on the power tool, then sets the desired depth level with the help of a screw on the side. It is convenient to turn this screw even with hands, as there are anti-slip notches on its head. Once the depth has been set, you can start working. The nozzle will rest against the material and will not allow the drill to go deeper than planned. The size of the stop is 60X68mm.
