DeWalt DW5440 1/2 x 16 x 18 Rock Carbide SDS Plus Hammer Bit, 2 Cutter

Using the DeWalt DW5440 is easy. First, make sure your drill is compatible with SDS Plus bits. Insert the bit firmly into the drill chuck until it locks in place. When starting to drill, apply gentle pressure to prevent the bit from walking. This bit is great for drilling into tough materials like concrete and masonry. As you drill, the four flutes will help clear away debris, so your drilling will be fast and efficient. Remember, the shank has three flats to keep it from slipping back into the chuck, which is for your safety. Don't use excessive force, as the bit is designed to handle hard aggregates with minimal wear. After use, clean the bit with a brush to remove any debris. Store it in a dry place to prevent rust. If you notice any signs of excessive wear or damage, it's time to replace the bit.
