Navigating tough drilling jobs just got easier with the DeWalt DW5504B25 Elite Series SDS PLUS Masonry Drill Bits. These drill bits offer up to twice the lifespan of BOSCH®* models when drilling through hard concrete and can handle rebar strikes without a hitch. The proprietary circulating cutting carbide design in select sizes ensures a longer life compared to previous DeWalt designs**, making them a smart long - term investment. Crafted in Germany using global materials, they're perfect for anchor installation. Thanks to the IRON BLAST TECHNOLOGY(TM), the bits are strengthened to resist fatigue and offer extreme durability. That's why DeWalt stands behind them with a NO BREAK GUARANTEE. When you choose these bits, DeWalt has your back. Each pack includes 25 high - quality bits. Key features include: Up to 2X the life of BOSCH®* in C35/45 concrete, longer life in C35 concrete compared to previous DeWalt 4 - cutter designs in select sizes, rebar strike resistance, a no - break guarantee, reduced breakage risk with IRON BLAST TECHNOLOGY(TM), high - speed drilling with a 2 - stage flute design, an anchor wear mark indicator for accurate hole diameters, and fast starts with accurate hole positioning using a full carbide pilot tip. Specifications: Bit diameter is 0.1875 inches, made with carbide - tipped material, and has an SDS Plus shank style.
Using your DeWalt DW5504B25 drill bits is a breeze. First, make sure your drill is compatible with SDS Plus shank bits. Insert the bit firmly into the drill chuck until it clicks into place. When drilling, start at a slow speed to get an accurate hole position, especially when using the full carbide pilot tip. Then, gradually increase the speed. You'll notice the 2 - stage flute design quickly moving debris away, which helps speed up the drilling process. When drilling in concrete, remember these bits can handle rebar strikes, but try to avoid them if possible. Check the anchor wear mark on the carbide tip regularly. Once it's no longer visible, it's time to replace the bit for proper anchor installation. To keep your bits in top shape, clean them after each use. You can use a brush to remove any debris from the flutes. Store them in a dry place to prevent rusting. If a bit fails while the anchor wear mark is still visible, DeWalt will replace it for free under their no - break guarantee.
