That's very interesting Mr. Rupert! Thanks.
I too am confused by the 3M coarseness ratings. It seems to be different on different sites. I remember when I got the Scotch-Brite's I used the grit chart from where ever it was that I purchased them from and used a marker to write it on the back of the belts. Why couldn't 3M have done that? The belt I used was blue. Blue? That tells me nothing. Thanks 3M! I had marked the back of the belt "VF" for Very Fine. Come on 3M... give us a consistent grit rating across all your belt line.
I'm guessing that the belts you are using are the same blue VF belts I used for the test? The talc belts don't seem to have mysterious color coding.
Right now I don't even know exactly what talc is. Is there talc in talcum power? Is it the same stuff they sprinkle on baby's butts to keep them dry and comfy in their diapers?
I'll have to check it out, find out more about it and possibly give one a test for deburring.
If you or anyone else here for that matter have done any real testing using clean 3M talc belts for deburring, please post!
