Inquiry (采购产品): Sanding Disc. I need to know what type of sanding disc. I need to use to grind on Alum, stainless, and mild steel. I have been told that there was a difference. I also have been told that if I use the wrong sanding disc. made out of the wrong stuff that it would contaminate the weld. Is this correct? would you please e-mail me of what I need to grind each. I need to know what the disc is made out of. If you need to talk with me I can be reached at ( 256 )235-7701 or E-mail me at LeeT@anad.army.mil Any information you can give would be greatly appreciated.
