Using the DeWalt DW5408 drill hammer bit is easy. First, make sure your drill is compatible with the SDS - Plus shank style. Insert the bit firmly into the drill chuck. When you start drilling, apply steady pressure, and let the bit do its job. The variable helix pattern on the two - stage flute design will quickly move debris away, so you don't have to worry about clogging. For best results, keep the drill perpendicular to the surface you're drilling. As for maintenance, after each use, clean the bit with a brush to remove any debris. Store it in a dry place to prevent rusting. Remember, this bit comes with a NO BREAK GUARANTEE as long as the wear mark is still visible. But be aware that this guarantee doesn't apply to DW5400, DW5401, and DW5401B25 models.
