Using the DeWalt DW5821 drill bit is easy. First, make sure your drill is compatible with the SDS MAX shank style. When starting to drill, the pilot point design will help you get a quick start into the concrete. Just position the bit at the right spot and start your drill. You'll notice that the optimized flute design quickly removes dust from the hole, allowing for fast drilling. When drilling, you don't have to worry too much about hitting rebar because this bit is designed to resist breakage. But still, try to avoid excessive force. As for maintenance, after each use, clean the bit to remove any dust or debris. Check the anchor wear mark on the flute regularly. Once the wear mark is no longer visible, it's time to replace the bit to ensure proper anchor installation. If your bit fails for any reason while the anchor wear mark is still there, DeWalt will replace it for free, so you can use it with confidence.
