About this specialty power tool

This is a cordless caulk and adhesive gun from Milwaukee, built around an 18-volt lithium-ion battery and sized to take a 20 oz. sausage-style cartridge. The kit comes with one 1.5 Ah M18 battery and a charger, so it is ready to use straight out of the box. It is a specialty power tool, meant for dispensing caulk and adhesive without a manual trigger squeeze. This kit suits anyone who already owns M18 batteries or tools and wants another cordless option for sealing and bonding jobs. Because it is an M18 tool, check that you plan to run it on that platform. The kit includes one battery, so if you want to keep several batteries charged for longer sessions, you would need to buy extras separately. Confirm that a 20 oz. sausage cartridge matches the cartridges you typically use.
