DeWalt DW5405B25 DeWalt 3/16 x 8 x 10 Rock Carbide™ SDS+ Hammer Bit (Bulk 25), 2 Cutter

Using your DeWalt DW5405B25 Rock Carbide™ SDS+ Hammer Bits is easy. First, make sure your hammer drill is turned off and unplugged. Insert the bit into the SDS+ chuck of the drill until it clicks into place. Once it's secure, you're ready to start drilling. When using the bits, start with a slow speed to get the hole started, then gradually increase the speed for faster drilling. Always wear safety goggles to protect your eyes from debris. As for maintenance, after each use, clean the bits with a wire brush to remove any dirt or debris. Store the bits in a dry place to prevent rusting. If you notice the bit is dull or damaged, it's time to replace it to ensure continued efficient drilling.
