Yes, the difference is the thickness of the disc. A cutting disc will be thinner than a grinding disc. The 4-1/2" x 1/8" disc you have should work well. Typically the grinding discs are at least 1/4" thick. You can't put much side load on the thin cutting discs without breaking them, but you can use substantial force with the thicker discs.
