DeWalt DW5401B25 DeWalt 5/32 x 4-1/2 x 6-1/2 Rock Carbide™ SDS+ Hammer Bit (Bulk 25), 2 Cutter

Using the DeWalt DW5401B25 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 chuck until it clicks into place. When you're ready to drill, apply steady pressure and let the drill do the work. The four - flute design will help clear debris quickly, so you can drill faster. As for maintenance, after each use, wipe the bit clean with a dry cloth to remove any dust or debris. Store the bits in a dry place to prevent rust. Be careful not to overheat the bit during drilling, as this can damage the carbide tip. If you notice the bit isn't drilling as effectively as before, it might be time to replace it.
