DeWalt DW5403B25 3/16 x 4-1/2 x 6-1/2 Rock Carbide™ SDS+ Hammer Bit (Bulk 25), 2 Cutter

Using the DeWalt DW5403B25 Rock Carbide™ SDS+ Hammer Bit 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 drilling, apply steady pressure but don't push too hard. Let the bit do the work. This bit is great for drilling into rock and other hard materials. As for maintenance, after each use, clean the bit with a brush to remove any debris. Store it in a dry place to prevent rust. If you notice the bit isn't drilling as effectively as before, it might be time to replace it. Always wear safety goggles and appropriate protective gear when using this bit.
