Super-strong and reliable, the Milwaukee M18 18-Volt Lithium-Ion Cordless 10 oz. Caulk and Adhesive Gun delivers incredible pushing force for your toughest jobs and provides exceptional bead control.

Easy to use and control, the rotating collar maximizes bead control around turns and with the interchangeable quick-change carriage design, you can quickly change between 10 oz. carriage, quart-sized carriage and 20 oz. sausage barrels. Ideal for the jobsite or for DIY projects at home, with the included long-lasting M18 REDLITHIUM battery, 200 tubes of 10 oz. construction adhesive can be dispensed on one battery charge.

We had a very large 30 x 60 shop with OSB interior walls that we needed to caulk. The Milwaukee saved me from my hand falling off. Worked perfectly but took a bit to get use to running a bead at the right speed. Easy load, battery power holds up great for 12 tubes and counting now. I would recommend this product for large jobs.

Make sure to remove caulk tube by unscrewing the holster from the base of the gun and slide it out and away from piston - it’ll save you from pulling caulk through your gears if any blowout were to happen from the inside back of the caulk tube. Tremendous purchase and a carpal tunnel saver, lol!
