Using the DeWalt DWA8951H Elite Series steel cutting wheel is easy. First, make sure your cutting tool is compatible with the wheel's arbor size (5/8'-11). Then, securely attach the wheel to your tool. When you're ready to cut, turn on the tool and gently guide the wheel through the metal. You can use it to cut rebar, heavy - wall pipes, and sheet metal. Just keep the tool steady for a smooth cut. As for safety, always wear safety goggles, gloves, and appropriate clothing. Don't exceed the maximum RPM (13300) of the wheel. After each use, clean the wheel to remove any metal shavings. Store the wheel in a dry place to prevent rusting. With proper use and maintenance, this cutting wheel will serve you well for a long time.
