The most powerful cordless caulk and adhesive gun on the market, the Milwaukee 2641-20, offers the most bead control. Deliver caulk or adhesives smoothly and steadily, even with the highest viscosity materials, with the incredible pushing force of the M18TM Cordless 10-oz Caulk and Adhesive Gun. All-metal gears provide an industry-leading 950 lbs of force, and CFTTM Constant Flow Technology eliminates motor oscillation for steady dispensing and even beads at all viscosity levels. A variable-speed trigger and six-setting maximum speed dial optimize the tool's 0-21 inches per minute (IPM) flow rate. The exclusive Milwaukee anti-drip mechanism prevents oozing of excess material when the trigger is released. A rotating collar gives you maximum bead control around turns, and the quick-change carriage design lets you change between 10-oz, quart and sausage-style containers. The M18 REDLITHIUMTM Battery (sold separately) lets you dispense more than 200 10-oz tubes of construction adhesive on one charge. The gun comes with a 10-oz carriage, 10-oz plunger rod and piston assembly.

Rated 4 out of 5 by from Doesn’t work with bulk caulk I love how this caulk gun performs. However, I am a little surprised that there is no option that allows it to work with Bulk Caulk. I use my caulk gun to seal the joints, and gaps around pre-cast concrete buildings. Although, I can buy the caulk I need in 20oz tubes; bulk caulk is cheaper. I was using a JES 20oz/Bulk Caulk Gun prior to purchasing the Milwaukee. Needless to say the battery operated gun is much easier to use, especially in the winter. Although, having the ability to use bulk caulk, as well, would save me time, money, and keep trash to a minimum.

Rated 5 out of 5 by from To the review above me, take note. With my big 20oz tubes life is great, because I bought the 2643-21 which is made for 20oz tubes. This one works great too, when you need something smaller, like a 10oz tube.

Rated 5 out of 5 by from Milwaukee M18 Cordless Caulk Gun Just finished using the gun to caulk around a new shower enclosure. Once you get used to the feel of the tool and the automatic retracting of the plunger it does an amazing job of controlling the amount of caulk that comes out. I was able to caulk both sides of a sliding shower door in about 10 minutes from start to finish with a very minimal amount of waste.

Rated 5 out of 5 by from Caulking gun It's an efficient and quiet tool which I purchased to replace my 25 year old 12v Milwaukee cordless caulking gun that still functions to this day!
