Rated 5.0 out of 5.0 by This drill kit is incredible! From the moment I opened the case, I knew that this drill was everything I needed in a combo kit. The heavy duty construction, quick battery charger, extra battery, and impact handle makes this tool exactly what I need for every project. The 18 volts gives plenty of power for every job around my house. So far, I have used it to install a coat rack, hang a shower curtain, and drilled some holes in my basement wall to hang lighting. The battery came half charged and still has 1 bar left after 4 jobs. The charger took under an hour to charge! That is awesome! I would most definitely recommend this great drill! Please see my photos and video. Happy drilling! May 28, 2013
Rated 5.0 out of 5.0 by Professional Quality This item replaced an 18V that I have had for almost 13 years. The lightweight design is much more comfortable and easy to use than its predecessor. I purposely tried to run down a fully charged battery the first day. Where the older unit usually started to run down, this new unit kept right on going. To tell you the truth, I'm on my second day and it is still going strong. So far the battery pack appears to have over three times the running time than the older NiCad 18V unit. The torque is unbelievable for this small unit. Quite impressive. All I can say is you better hold on tight...this thing means business. Great drill! I should have gotten one sooner than this.

Rated 4.0 out of 5.0 by Good Drill I do security alarm installation and have been using a white Makita 18V lithium-ion drill (a lighter duty class of drill but comparable) for the last 3 years. Over that time I've been very very impressed with those little drills. I was headed to the store to buy another one for a new employee with I spotted this (Milwaukee 18v) bad boy with 3 batteries for $229 and I had to give it a try. This Drill is MEAN. that's the best way to describe it. It's fast, torque-y, and tough. things I like more about the Milwaukee: More Speed! (I use spade bits alot) More Torque (big big big difference) Battery life indicator things I like more about the Makita: better grip lighter better chuck (doesn't loosen ever) easier to remove battery more controllable speed Things I don't like about the Milwaukee: Chuck loosens up if not really tight heavy-ish off balanced (top heavy) battery a little harder to remove. Things I don't like about the Makita: Not enough torque for heavy drilling (3/4" auger bits kinda work) Slow Battery life is so so Overall I think the Makita is a better drill for light duty drilling and great for screw work. I think the Milwaukee is a beast in heavy drilling and okay at screw work. I'm still within 90 days but I can't bring myself to take the Milwaukee back and buy the Makita. The Milwaukee is just that much better at drilling.... and the Makita feels like a toy after using the Milwaukee for a couple months.. June 16, 2012
Rated 4.0 out of 5.0 by Great Tool but would get the bigger batteries This drill is powerfull! It has a ton of torque. I use it to drill the frames of pickup trucks to install 5th wheel and gooseneck hitches. The batteries were not big enough for my needs so I returned and got the same drill with the 3 amp hour batteries. (versus the 1.5 amp hour batteries in this kit) I previously have owned makita, bosch, and dewalt. None of those had this kind of power. The warranty on this thing is also one of the best on the market. June 5, 2012
Rated 5.0 out of 5.0 Hands Down...The Best Drill I've Owned! I've been wanting this drill in the worst way ever since I received an email from Milwaukee announcing it's availability. Milwaukee quality, 18 volt FUEL, Brushless motor, and 2 Li-Ion batteries...Sounds like a wish list. When this drill arrived, I was not disappointed. The fit, finish, and quality were visibly apparent. When I picked up the drill I was amazed at how well it felt in my hand. It had an outstanding balance, and felt as if the grip was molded for my hand. Switch placement was dead-on for ease of forward / reverse selection. Running through the clutch settings and Hi / Low speed's produced a smooth, yet continuous fluctuation in speeds. With the motor being brushless, the sound this drill makes is very unique, unlike all the other drills I've owned. There is absolutely no motor strain or high-pitched whine witnessed, even after driving about a dozen 3" outdoor screws in a project I was finishing up. This drill simply didn't skip a beat. The batteries are remarkable. After driving all those screws into pressure treated 2x6's, the battery indicated only one bar of charge used. I easily would have changed batteries at least once using my old Li-Ion's in my other drill. It appears the M18 FUEL speaks for itself. I love the fact that Milwaukee had the foresight of the charger being of dual use. This way, I can take the batteries from my Milwaukee 12 volt and charge them along with these using the same charger, thus eliminating yet another battery charger laying around. Nice touch. There is absolutely nothing I don't like about this drill...It is easily the best drill I've ever owned. I am thrilled with it, and know that this beast of a drill will long be a productive asset within my tool arsenal. May 20, 2013
Rated 5.0 out of 5.0 by Milwaukee does it again! Milwaukee puts it to the competition again! This drill has so much torque! Picked it up the other day and was drilling 3/4" holes with a spur auger with no problem! I had the chance to demo it in the store and it blew away every drill that is carried in the store. This one is a winner and the benchmark for every other brand! April 4, 2012
Rated 4.0 out of 5.0 by Drill handles nicely, batteries have lasted, warranty repair was painless I've had this drill for 18 months, using it multiple times a week for a variety of tasks including high torque work like hole sawing. The drill is very solid and nice to use, it has a ton of torque and the drill body is really durable. The two standard sized batteries have lasted really well. The drill stopped working a few weeks ago...some kind of issue with the gear casing, but I returned it for a repair under warranty and they had it back to me in 8 days, working perfectly, free of charge. So....slightly surprised that an expensive drill would fail after 18 months, but they made up for it with excellent service. October 15, 2013
Rated 5.0 out of 5.0 by Great drill for the competent homeowner I bought this drill last week to replace a 5 year-old Rigid 12V. The difference (as expected) was night and day. It's extremely powerful and I can't imagine any home improvement project that it wouldn't be able to handle. I can't speak for it's ability to drill through masonry/concrete but it has no trouble driving 2.5 inch screws into studs without pilot holes. It's a bit expensive but is worth every penny.
