Complete Restoration of Old Bosch Angle Grinder GWS 21-180H🔧

In this video, I fully restore an old Bosch angle grinder GWS 21-180H step-by-step. The tool was completely disassembled, cleaned with gasoline and diesel, and the body was fully repainted.
The armature was rewound, lathed, and dynamically balanced to ensure smooth operation.
Finally, the parts were reassembled, and the grinder was tested under power to confirm successful repair.

If you're into power tool restoration, DIY repairs, or learning how to rewind armatures and fix electric tools, this video is for you!
