DeWalt DCK423D2 20V MAX 4-Tool Combo Kit (2.0 AH)

Using the DeWalt DCK423D2 Combo Kit is a breeze. For the drill/driver, first, choose the right bit for your job. Then, adjust the speed according to the material you're working on - use the lower speed for harder materials and the higher speed for softer ones. When using the circular saw, make sure the blade is sharp and properly installed. Mark your cut line clearly and guide the saw steadily along it. For the reciprocating saw, use the keyless blade clamp to quickly change blades when needed. The LED worklight is handy for dark work areas - just turn it on and place it where you need light. As for safety, always wear safety goggles when using any of these tools. Don't use the tools if they're damaged. To keep your tools in good shape, clean them after each use. Wipe off any dust or debris. Charge the batteries fully before storing them for a long time. And store the tools in the provided bag to protect them from damage.
