I managed to find a large angle grinder at a second-hand Japanese goods store. It's a Kosoku brand, an old Japanese brand. According to my research, it's the HSF 182 model, manufactured around the 1980s. Unfortunately, it's in a rather sorry state with a seized spindle and switch. The exterior is covered in thick layers of grime, and the screws are severely rusted and difficult to remove. To restore this angle grinder, I'll be sandblasting and rust-blasting each component, and replacing any parts that can't be repaired. Let's see how the restoration turns out!
* Angle Grinder Information *
- Brand Kosoku
- Frequency 50/60 Hz
- Type HSF182
- VOLTS 110V
- DISC Wheel 180*8*22mm, 4300m/min

I'm very happy to receive your feedback, advice, suggestions to improve myself.
