Using the DeWalt DW5472 drill bit is straightforward. First, make sure your drill is compatible with the SDS Plus shank style. Then, insert the bit firmly into the drill. When starting to drill, press gently to let the full carbide pilot tip do its job for an accurate start. When drilling, the 2 - stage flute design will quickly move debris away, keeping the drilling speed high. Remember to check the anchor wear mark on the carbide tip. If it's no longer visible, it's time to change the bit for proper anchor installation. Regarding maintenance, after each use, clean the bit to remove any concrete or debris. Store it in a dry place to prevent rust. Also, if the bit fails while the anchor wear mark is still visible, don't worry. DeWalt will replace it for free under the No Break Guarantee.
