The Milwaukee 2497-22 M12 12-Volt Lithium-Ion 2-Tool Combo Kit includes a hammer drill and impact driver, both designed to be lightweight and tool-belt portable. Each has a built-in power gauge that indicates the remaining charge in its lithium-ion battery, which charges in as little as 30 minutes on the included charger. These tools also come with a carrying case for added convenience. Cordless tools powered by Red Lithium batteries deliver more torque, more power, and longer run-time than the competition.
