The M12 Caulk and Adhesive Gun is the lightest, most compact cordless powered caulk gun on the market today. With up to 400 lbs. of pushing force the M12 Caulk Gun easily dispenses everyday construction sealants and adhesives. The combination Variable Speed Trigger and Max-Speed dial allow for total application speed control. The 360 degree Rotating Collar delivers maximum control around turns. The tool also features auto-reversing anti-drip, a seal puncture tool and durable hang hook for versatility on the job. Powered by the revolutionary M12 REDLITHIUM Battery, the M12 Caulk Gun will dispense up to 150 10 oz. tubes of building sealant on one charge. This configuration is designed to work with 10 oz. cartridge style material containers. Milwaukee also offers accessory conversion kits to change to 20 oz. sausage packs (48-08-0905) and Quart cartridges (48-08-0910).

Rated 4.9 out of 5 by 8 reviewers.
Rated 4 out of 5 by Has it's place, Will take getting used to. I'm over 50 and a professional contractor. My right forearm, that has gunned thousands of tubes of caulk, is injured from overuse. I decided to try this gun on a big paint job. It is well made and has plenty of power but lacks the finesse of a manual. It is also quite heavy for a full day job. The biggest problems I am having is that when the trigger is released, it goes into the reverse function to stop the flow. It then takes several seconds to get another flow of caulk. This gets tiresome. Also, the flow seems to start slow, then get higher and higher so you have to move to its' speed not your own, starting slow and moving faster. I need to experiment with cutting the tube smaller than I usually do, different speed settings, etc. Right now, I think this gun will be best for large cracks and long cracks that can be walked and caulked because the trigger can be left down through the entire operation. I use Z-Pro Acu-vac manual guns. (the best gun ever made) I will not get rid of them but will try to use the M 12 as much as I can. Who knows, I might learn the intricacies of this gun and how best to use it. Another negative is that it doesn't have a cutter. You have to use a snip or knife which is kind of a pain. I think if the manufacturer added a variable speed trigger instead of the knob and switch it would be a lot more user friendly. August 18, 2014
Rated 5 out of 5 by It's easy to use. We are remodeling our house and needed to do a lot of caulking around the new trim, etc. I have arthritis and couldn't use a regular caulk gun. This cordless caulk gun has been the answer! It is easy to use. I love the automatic pull back feature when the trigger is released so no messy globs. The speed dial is great at controlling how fast the caulk comes out. I have used up two tubes of caulk and the battery is still fully charged. Clean up is easy because there aren't any messy globs. It isn't very heavy either. I wouldn't have been able to do the caulking without this gun. February 11, 2014
Rated 5 out of 5 by Perfect! Bought this to caulk around the house because I have no hand strength left after years of secretarial work to operate the manual caulk gun. It's exactly what I needed. It lasts all day and is really easy to operate. It's not too heavy, either. Great product that gets the job done. June 15, 2013
Rated 5 out of 5 by This is verry good for polly calk It makes stiff and thicker calks easy to use, great for older guys with less strength and long jobs. the backup feature when you take your finger off the trigger you do not get drips. December 24, 2013
