Using the DeWalt DWA8958F cutting wheel is easy. First, make sure your cutting tool is compatible with the wheel's arbor size, which is 0.875 inches. Install the wheel securely on your tool. When cutting, hold the tool firmly and apply steady pressure. You can use it to cut different metals like rebar, thick - walled pipes, and sheet metal. Remember to wear safety goggles and gloves to protect yourself. As for maintenance, keep the wheel clean after each use. Check it regularly for any signs of damage. If the wheel is cracked or chipped, don't use it and replace it right away. Store the wheel in a dry place to prevent rusting. This will help the wheel last longer and keep performing well.
