About this specialty power tool
This is a cordless caulk and adhesive gun from Milwaukee's M12 12V lithium-ion line, built around a 20 oz. aluminum barrel. It suits anyone who regularly applies caulk or adhesive and wants to skip hand pumping. Before buying, check that you already own M12 batteries or are happy to use this battery platform, since the tool is powered by M12 packs. This is a kit, so the battery and charger come with it; the 20 oz. barrel size is the main dimension to keep in mind for your project.
