Using the DeWalt DW5503B25 drill bits is easy. First, make sure your drill is compatible with SDS Plus shank bits. Insert the bit firmly into the drill chuck. When you start drilling, use the full carbide pilot tip for a quick and accurate start. For high - speed drilling, the bit's 2 - stage flute design will move debris away quickly, so just keep a steady hand and let the bit do its job. When drilling, be aware that these bits are resistant to rebar strikes, but try to avoid hitting rebar if possible to extend the bit's life. Check the anchor wear mark on the carbide tip regularly. Once it's no longer visible, it's time to replace the bit to ensure proper anchor installation. After use, clean the bits with a brush to remove any debris. Store them in a dry place to prevent rusting. If your drill bit fails for any reason while the anchor wear mark is still visible, don't worry, DeWalt will replace it free of charge according to their NO BREAK GUARANTEE.
