DeWalt 20V MAX 4-Tool Combo Kit DCK421D2 vs DeWalt DCK330P2 3-Tool Combo Kit

Buy the DCK421D2 if you want four tools and a light, or if you are outfitting a truck for framing, rough-in and trim work. Buy the DCK330P2 if you want fewer but better tools: brushless motors, a compact drill and 5.0Ah batteries that run longer between charges. The 421D2 wins on breadth; the 330P2 wins on motor efficiency, battery capacity and drill size. Owners of the 421D2 praise the DCF885 impact driver and the saw's bevel cuts, but the brushed motors and 2.0Ah packs are the common complaints. The 330P2 has fewer owner reports, and its kit drops the work light.

• Choose the DeWalt 20V MAX 4-Tool Kit if you need a circular saw, drill, impact driver and work light in one bag and want the most tools for the money.
• Choose the DeWalt 20V MAX Brushless 3-Tool Kit if you value brushless motors, 5.0Ah batteries and a shorter drill over having a fourth tool.
