Two questions in one!
1. Can anyone identify the type of wheel in the pic? The only abrasive part seems to be at the edge, and that's pretty smooth. (It's a Clarke grinder that we bought second hand.)
2. What wheel is best for sharpening tungsten electrodes for TIG welding? If it's just a basic grey stone (120 grit?) can you recommend a decent quality make that's likely to hold together/ be safe?
Thanks in advance for any thoughts.
