Using this Milwaukee drywall blade is a breeze. First, attach it securely to your oscillating multi - tool. For starting a cut, use the piercing tips on the sides to make a clean entry into the drywall. When making straight cuts, let the curved leading edge do its job for a smooth result. For detailed cuts like circles or curves, rely on the back - facing side blade. To get an exact fit, use the notches on the side to shave off any excess drywall. As for the depth, check the laser etching for guidance. When it comes to maintenance, after each use, clean the blade with a dry cloth to remove any drywall dust. Store it in a dry place to prevent rusting. And always make sure the blade is firmly attached before use to avoid any accidents.
