Besides, high-quality grinding discs as well as flap discs work with right-angle grinders as a system. An old jalopy (that is, a low-quality grinder) with fancy tires (high-quality grinding disc) may drive a little better, but it's still not the smoothest ride. 2. Be safe. Using the right tool for the job promotes safe operation.
