DeWalt DW5404B25 3/16 x 6-1/2 x 8-1/2 Rock Carbide SDS+ Hammer Bit 25 Pack, 2 Cutter

Using the DeWalt DW5404B25 rock carbide SDS+ hammer bits is easy. First, make sure your hammer drill is compatible with SDS+ bits. Insert the bit firmly into the drill's chuck until it locks in place. When you start drilling, apply steady pressure, but don't push too hard as the bit's design is made to cut through rock efficiently on its own. As for safety, always wear safety goggles to protect your eyes from flying debris. Also, use ear protection because the drilling can be quite noisy. If you're drilling for an extended period, take breaks to avoid overheating the bit and the drill. To keep your bits in good condition, after each use, clean the bits with a wire brush to remove any debris. Store them in a dry place to prevent rusting. If you notice the bit is dull or damaged, it's time to replace it for the best drilling results.
