I feel I need to add a review for this product to counter the previous low ratings which don't accurately reflect the quality of this product.

I have owned this kit for about 2 weeks and have used them both in 1 fairly large project requiring drilling large holes in wood and metal and driving large screws. The power of both the drill and the driver are phenomenal. The battery life is excellent. I love how the power just continues at 100% until the battery is actually spent. AND, the charger is fast! If you do need to recharge during a project, it will be done in around 30 minutes.

One of the best things about the Milwaukee batteries - the warranty. They are warranted for 2000 charges or 5 years (don't know how they determine number of charges but I assume the battery has a counter inside). I won't be using these commercially so I'm expecting them to last a bit longer than the stated 5 years. We'll just have to wait and see.'

UPDATE - July 2014
I wanted to add that I've been using these tools a couple times a week for the last (nearly) 4 years and they are still going strong. Really happy with this purchase.

UPDATE 2 - July 2016
I am still using these on a regular basis. Probably once or twice a week. The batteries are still holding their charge like they were new.

I love these tools. I bought my first set 5 years ago after working with a friend who had the same set. Even after dropping the driver 15ft. onto concrete a few times (not recommended) and using the drill to bore through ironwood until it started smoking (also not recommended) they kept on trucking. I just bought a second set for a big project coming up and I'm sure they'll both work marvelously. The batteries are also great so long as you don't let them sit for a year without charging them. Over all I'm learning to love Milwaukee tools even more then the DeWalts I used to use!

I've had this kit on my want list for a LONG time. Happy to finally get it!

I've used the two tools on only a couple of jobs, but they have performed well. The 3.0AH batteries perform well, recharge quickly. There is a LOT more arcy-sparky from the brushes than I've seen with any other battery operated tools (I've used Makita and DeWalt). Maybe that will decrease with more use. If you work in the proximity of something flammable...buy the Fuel/brushless series.

The LED light on the Driver/Hammer unit is pointedly useless. It seems Milwaukee actually TRIED in their design to NOT illuminate the work surface. If that was their intent, they did an excellent job!

The chuck on the Driver/Hammer is less than smooth. I expected better from Milwaukee. I don't anticipate it to be a use/longevity issue but it's a scritchy-ness I could do without.

The LED is fine on the impact...its much shorter body making that true.

I appreciate the tools coming with a carrying bag, but it could be a LOT more useful with not too much effort. How about a couple of pouches/sleeves? Trying to zip the bag shut may well lead to utterance of an expletive or two. The bag was designed with no thought at all.

I read a lot of rewiews so I'll write this as to answer the questions that I had about this product.

I am an electrician by trade, and have used a large variety of drill/impact kits over the years. I have an old ni/cad dewalt 18 volt kit at home which has served my very well and does not owe me a thing. In fact, I've owned it for close to 10 years now and have only replaced the batteries on it once (2 years ago). It is still going strong, but I decided to upgrade to lithium ion and an impact driver.

Until six months ago, I had been using a lithium Dewalt set with virtually no issues. Since then I've changed jobs and have used the Redlithium Milwaukee kit.

So when deciding on what to buy for weekends, it came down to these two brands. The impact driver was very similar between the two brands. The drill was also similar but the chuck was much more variable and versatile on the Milwaukee. Also the way the batteries clip into the tool or charger. Milwaukee is much more tight and solid. I believe the Milwaukee is the better tool overall.

This kit came with M12/M18 charger, 1/4" Impact, 1/2" hammer drill/driver, (2) large M18 3 amphour Redlithium batteries, and a carry bag.

I have no foreseeable problems with this set and am very happy with my choice. I bought mine for $228 and see that now they're going for $219. $300 in stores.

My old set of Milwaukee tools with NiCad batteries are still working great, but the batteries have eventually been turned into bricks. I've replaced them several times, but the cost of replacing the batteries with new ones that will just go dead again anyway is ridiculous, so I made the decision to jump to the pro-level Lithium Ion M18 series with the XC batteries. I did it initially with the 1/2" cordless impact to test with, since I needed one anyway (can't use air when away from the shop), and I was very impressed.

So I finally made the jump to the M18 series for the drill and 1/4" impact for driving screws and such. I just got them, but they seem very solid and very fast. This kit comes with two XC batteries and a charger, which compliments the two XC batteries and charger that came with my previous 1/2" impact purchase. I think at this point I can purchase bare tools and still be good to go. My existing stand-by Hitachi 1/4" impact driver is still going strong, but it sure is nice to have a LONG Li-Ion battery life that I can swap around with all my other cordless tools.

These tools are an improvement over the old versions in several ways. One of the ones I noticed first is that they each come with an LED light over the trigger now, to help light up where you're about to drill and during drilling. This doesn't mean much outside during the day, but in tight quarters or at night it can make a world of difference. The old drill didn't have a hammer function, and the receiver on the hammer drill looks a lot larger than the old model as well. The batteries are big (and a little heavy--but that's a price I'll pay all day every day), quick to charge, last a very long time on a charge, and they can actually be left on the charger unlike the old NiCad batteries.

I had to decide between this set or the Factory-Reconditioned Milwaukee 2691-82 18-Volt Cordless M18 Lithium-Ion 2-Tool Combo Kit with the slim-line batteries. I'm so glad I went the XC route instead. Even if you don't use your tools that often, go ahead and pony up for the higher end version with the much bigger and better batteries. You'll thank yourself someday...
