DeWalt DW5447 5/8 x 10 x 12 Rock Carbide SDS Plus Hammer Bit, 2 Cutter

Using the DeWalt DW5447 hammer bit is easy. First, make sure your drill is compatible with SDS Plus bits. Insert the bit into the drill chuck firmly, and the three - flat shank design will keep it from slipping. When drilling, start at a slow speed to prevent the bit from walking. As you drill, the four flutes will clear the debris, so you can work efficiently. For safety, always wear protective gear like goggles and gloves. When you're done using the bit, clean it to remove any debris. Store it in a dry place to avoid rust. If you notice excessive wear or breakage, it's time to replace the bit. This bit is designed to handle tough aggregates, so don't be afraid to use it on hard materials, but always operate the drill within its recommended limits.
