NO MORE HAND CRAMPS.
I read and watched plenty of reviews on this caulk gun prior to my purchase. They were all over the place. In fact, one YouTuber said it was an overpriced and under performing tool. Well, I beg to differ. MILWAUKEE makes the best tools. Rugged…dependable…convenient. I also ordered the large 29 oz tube accessory. I have put 2 large tubes of polyurethane caulk through it without any problem. Filling sidewalk and driveway cracks is no longer the chore it used to be. PRO: plenty of power, nicely weighted and balanced, good range of caulk speed easy to change out the caulk accessory. CON: yes, it is expensive but for what you get it is worth the money. I currently own 18 Milwaukee tools and continue to dream of the other 280. It does take a little practice to know how much to trim the caulk tube tip, and adjust the speed correctly But a few times on a piece of scrap wood should be all you need. WORTH EVERY PENNY FOR THIS TOOL ... show more

Excellent gun!
Excellent and dependable electric caulking gun. I use a lot of different thick viscosity sealants. You can’t use a regular caulking gun to squeeze them out because they just won’t move. I tried some Chinese knock off and they worked for a little while but broke. I’ve been using Milwaukee caulking guns for 30 years and I knew better than to try something cheap. Save your money and go ahead and buy this gun. You won’t regret it. ... show more

Love Milwaukee!!
I make moss walls for a living and ordered this to use as my "glue gun." It works great! The battery is ordered needs to be longer at the base to keep the gun stable so it won't tip over. Keep that in mind. It tips over with the smaller batteries. Otherwise its a great product and I now have M18 batteries so sky's the limit on my next tool purchase. 😁 ... show more

A little heavy a little more then I need but definitely. Last linger than the m12.
Works great, pretty interchangeblr with aftermarket accessories. but is a bit heavy and hard to one hand.. the 12 volt version is more versatile but if ur pushing automotive urethane or other really thick glue the 18 volt will reduce wear n tear on the gun. 18 volt is not needed for any of the glue I've used, and the 18volt is slower to back off (the anti drip) when u let go of the trigger. I found the 12 volt easier to use and battery life to be very similar. However my main pro here is the reduction in wear and tear. 12 volt will do 95% of the jobs tho. So if u like to one hand it go with the 12. ... show more

Nice even flow, but heavy and difficult to clean
Having a motorized continuous flow allows you to produce a nice, even bead of material for long runs. No need to stop moving while you get another squeeze on a manual lever. For very visible jobs, like caulking bath and shower areas, sinks, etc, that smooth, even flow and the ability to slow the speed down for control does help make a much nicer finished job. Know that with an M18 battery attached, this tool is fairly heavy, and if you are doing a large job, it can get tiring, especially if you need to hold it up high, but the larger batteries will keep it running all day. The main problem with it is cleaning. It has deep gear teeth, spring loaded slides holding the tubes, some unnecessary small radius concave curves added to the back of the piston head, and a screw on connector attaching the tube holder to the gun with small crevices. You will always have tubes that squeeze some material out the back of the tube, which oozes into the tool's piston and gears, and into the crevices around the screw threads. On short jobs I've spent more time cleaning out the tool than I did dispensing material. On very messy jobs like sealing rooftop flashing, I've sometimes bought cheaper guns to just throw them out rather than clean the asphalt tar out of the gun, and that's very much the case with this Milwaukee caulk gun, so you still get a hand cramp from a manual dispenser for many jobs where you'll leave this gun unused, which makes it less valuable than it could be. ... show more
