Milwaukee one tool kits include a single power tool, two batteries and a charger which best suits the capacity of the included battery packs. All this gear is stored in a Milwaukee tool bag, heavy duty carry case or a PACKOUT™ box. Occasionally these single tool kits also contain hand tools and accessories providing the user with all the gear they need to put their new tools to work. We stock 1-tool kits in both the M12™ 12-Volt and M18™ 18-Volt ranges, most of which now include brushless power tools and tools in the FUEL™ system. A Milwaukee 1-tool kit is a great way to expand your tool collection, providing you with premium quality performance for a great price.
