The model number tells you if it is a kit or a bare tool. The -20 after the model # means its a bare tool. The batteries can be ordered online or at most popular hardware stores.

will the 18V NiCd battery work with the mod.# 2641-20 caulk gun

If you have a lot of caulking to do, this is the tool to get! No longer do my arms cramp up applying caulk. I slapped on an M18 CP 2.0 battery, cut the tip and broke the seal of the caulking tube, and I was ready to go. This Milwaukee caulking gun is very easy to use! Just adjust the dial to the speed you want to output, use the variable speed trigger to further adjust the output, and finally, adjust the speed at which you move the caulking gun and you get perfect, consistent beads every time. Adhesive caulk tubes are hard to dispense by hand, but a cinch with this tool. I had a caulk tube of concrete repair and when I went to use the brand new tube, it was already somewhat dried up. Since I could not return the tube, nor did I want to lose what content was not dried up, I applied the trigger on this caulk gun until the caulk tube ruptured. I was then able to scoop up the concrete repair and apply it. Of the many, many tubes I've dispensed using this caulk gun, there has been no cleanup needed. I was shocked – unlike other manual caulk guns I've used, there was usually a mess on the inside push rod to clean up, but not with this one. I like how I can interchange the barrel to a sausage style when needed. Best of all, the anti-drip works flawlessly!

Very easy to use and came already setup for use. Has some weight but still very manageable. The adjustable speed gives you perfect control over laying down perfect beads. Ive ran 18 tubes of caulk through already and my battery still has 4 bars. This thing is fantastic on battery life.

It truly is the best way to get my caulk up in the hard to reach areas with a real firm feel and nice pressure sensitivity. When I pull my caulk out and this gun, everyone gathers and admires it for sure. Great work Milwaukee!

Used this with a 12ah battery. Used Locktite adhesive, some roofing shingles adhesive and some various caulkings. I really like this unit and it's pressure adjustment. Produces a nice continuous flow of material.
