M12 12-Volt 10 oz. Cordless Caulk and Adhesive Gun Kit
My Milwaukee boxed kit came with the bare tool and a M12 REDLITHIUM battery and 12V charger only.
The first thing I did with it was caulk a wall of siding and I realized I cut too much of the tip off and wound up having to go back and scoop some up but the gun worked so nice I chalked it up to just learning to use it.
The second thing I did was filled in some concrete cracks with a 2 part epoxy. The epoxy tube would not fit the gun because epoxy tube wall thickness is thicker than most and the plunger pad (Piston) diameter is too big around so I had to use my regular manual gun. One of these days I'll take the piston off and trim it down just a little bit so its more accepting of different types of caulking tubes (its a part that you assemble when you get this so it comes apart easily. Other than that this caulking gun is a pleasure to own and I don't think its worth knocking off a star for this review.

This thing actually works, but...
I purchased this to use installing a combined 150' of crown molding in two bedrooms, and then for other DIY homeowner projects as they come along. I chose the 12v instead of the 18v because of my anticipated infrequent use, the lower weight, and the lower costs of the tool and batteries. Initially, this gun is for the adhesive to attach the crown to the wall and ceiling, and for paintable caulk to touch up nail holes and crown joints. The gun lays a great bead along bonding surfaces, and you quickly develop a technique to apply the adhesive fast. Even with the recommended small hole cut in the adhesive tube end, you can lay on a lot of adhesive in short order. There is a speed adjustment dial with 6 number settings and click stops between each number yielding many speed choices. Also, the gun has a variable-speed trigger so adds even more flexibility to the device. My suggestion would be to set the dial at "2" to begin with and vary the speed with your trigger pull until you determine what speed will work best with your specific caulk or adhesive and the ambient temperature, how long your beads will be, and so on.

The 12v battery seems to last a very long time with the adhesive I'm using: four 10-oz tubes and still showing full charge. It also charges in about 30 minutes.

On the downside, this unit is still heavier than a manual caulk gun by far. If you're working overhead, e.g., caulking crown molding, it gets tiresome to hold. If you are used to working with a nail gun overhead, this gun is much lighter and you will have no problem. For work not overhead, the weight is not an issue at all.

CPOMilwaukee handled my order accurately and very quickly...positive experience all around.

Most of my DIY battery tools are DeWalt and Makita, this is my first Milwaukee. I'm impressed so far.

Pros
Easy To Use
Saved my wrist
This tool saved my wrist which suffers from carpel tunnel issues. First use was 26 tubes of 30 oz crack sealer in a morning. It worked perfectly. I have read other reviews and they commented that it drips when stopped. The machine has sufficient pull back to prevent this in most materials. The dripping can't be prevented especially in material like self leveling material, which will just drip out without any pressure at all. Caulk guns, whether mechcanical or powered can't pull the piston in the tube back, you can only pull the plunger back which this gun does very well. Couldn't be happier. I also bought the 10 oz optional cartridge holder. Doesn't seem that I needed the extra battery or the 18 volt model.

Best out there
I've been using a battery powered Wagner for the last 15 years. They stopped making them. I bought a Dewalt but it was heavy and the flow keeps going when you release the trigger. I first encountered milwaulkee when we had a broken windshield replaced and the tech was using one. I was impressed with it's operation so I purchased one to try out. This thing is light and easy to control. Appears to be well built. I even bought a spare as a backup unit.

Happy elbows!
I am a 50 year old professional plumber who has developed severe tendonitis in both of my elbows.I have to make a lot of Penetration's through the metal roof and siding of the buildings I work in ( vent pipes, furnace exhausts, etc. ) I have to seal the flashings with an extremely thick commercial sealant.In warm weather it's a chore, in cold weather it's nearly impossible to squeeze the trigger on a standard caulk gun. By the time I'm finished, my elbows are on fire! With this mighty little brute I just press the trigger and go! I was a bit apprehensive about spending that much dough on a caulk gun, but after the first use, I realized that this tool is worth every penny! Way to go Milwaukee!

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
