DeWalt DW5402B25 DeWalt 3/16 x 2 x 4 Rock Carbide™ SDS+ Hammer Bit, 25Pk, 2 Cutter

Using your DeWalt DW5402B25 Rock Carbide™ SDS+ hammer bits is a breeze. First, make sure your hammer drill is turned off and unplugged or the battery is removed. Insert the bit into the drill's chuck until it clicks into place. When you're ready to drill, mark the spot on the rock or other hard surface. Then, apply steady pressure and let the drill do the work. The four-flute design will help clear away debris, so your drilling will be fast and efficient. As for maintenance, after each use, wipe the bits clean with a dry cloth to remove any dust or debris. If they get really dirty, you can use a mild solvent. Keep the bits in a dry place to prevent rusting. And always remember, these bits are designed for hard surfaces like rock, so don't use them on other materials. With proper use and care, these bits will serve you well for a long time.
