Prazi PR-1000 Drill Mate 10 Ounce Adhesive and Caulk Dispenser Attachment for Electric and Cordless Drills

Bought it to use for windshield urethane which is pretty thick and it has no problem pushing it out. Attached to my craftsman drill in about 30 seconds. It would probably be too bulky for caulk though if it is in a tight space like a shower or something. If space isn't an issue though it works great.

did not work buy a real one..........

After countless hours of hand-cramping manual caulking of baseboards, crown moulding and door trim, I decided to purchase this Drill Mate as a hopeful powered alternative short of a dedicated electric caulk gun. This product did not live up to my expectations.Positives:1. The injected molded plastic parts do help to keep the overall weight down.2. It does perform the main function as advertised; spare hand cramping from manual caulking.Negatives:1. The overall weight with a full tube of 10 oz. caulk and a full sized portable drill makes the assembly unwieldingly big. I have an easier time man handling my cordless 15 gauge nail gun.2. There appears to be no "no-drip" feature. As soon as I stop the drill, it will continue to push anywhere from a few inches to nearly a foot of caulk. Some of you may think this is a result of running the drill a bit faster than I should have for the application. However, even purposely only pushing through an inch of caulk at the slowest speed and stopping, it will continue to push through another half inch. The only time it would stop is if I ran the drill backwards; something the manual specifically recommends NOT to do.3. The clamping mechanism for the drill body is a tad too short for my run of the mill Dewalt 9.6 volt drill. Only half the clamp will clear the chuck before I run out of travel on the clamp. The portion that does grab my drill only grabs the torque adjustor. So as I'm handling the full assembly, it's very easy to accidently rotate the whole drill relative to the Drill Mate and change the torque setting.Conclusion: This product can definitely still be useful but you'll need to use it a specific way.First, use the smallest drill with the shortest distace from the body to the end of the chuck you can find. This will ensure the clamps fit around the body and not hold it by the torque adjuster ring. This will also make the whole aseembly much easier to handle.Second, use the product when you plan on making long runs of caulk or adhesive without stopping. If you're caulking an entire room of trim, this will work great. If you're going to start and stop constantly, the dripping will annoy you to no end.Personally, I will probably end up buying a dedicated electric caulk gun.

It worked great. Did 15 tubes of caulk in no time

Used this to caulk the teak deck on our boat. Worked well.
