Good grip, enough power, lumbering per disc Carbide surprised me, but works perfectly. However, it is not a true mini circular saw, since we must adjust the depth of cut down the drive, resulting in a lower use of precision to attack in the middle panel. Finally, metal cutting produces hot debris burning plastic machine: for this use would require the piece is made of aluminum. Too bad, because it is a lightweight tool that allows to work on all thin panels.
