Using these DeWalt drill bits is easy. First, make sure your drill is compatible with the SDS Plus shank style. When starting to drill, use the full - carbide pilot tip for a quick and accurate start. This will help you get the hole in the right place. As you drill, the 2 - stage flute design with a variable helix pattern will quickly move debris away, allowing for high - speed drilling. Pay attention to the anchor wear mark on the carbide tip. When this mark is no longer visible, it's time to replace the bit to ensure proper anchor installation. Remember, these bits are designed to resist hitting rebar, but try to avoid it if possible to extend the bit's life. After use, clean the bits with a brush to remove any debris. Store them in a dry place to prevent rusting. If your bit fails while the anchor wear mark is still visible on the product head, don't worry. Just contact DeWalt, and they'll replace it for free.
