Milwaukee's M12 Line of Cordless Tools
I really, really like these things. First of all if any of you haven't used lith-ion yet, you're in for a treat. These batteries hold charges for a very long time, will never have memory problems and typically charge to full in about 30 minutes. I never though ni-cad was particularly convenient for somebody who doesn't need to use tools on a job-site but when I gave Lith-ion a try I was sold.
I've got the subcompact drill/driver, the impact driver, and the Hackzall. I'm a little embarrassed that I hardly use the Hackzall but suspect it will be handy when I purchase my own home, which I fully intend to be a fixer-upper. Overall I'm impressed with the power output and longevity of the battery on all these tools for what they're capable of. That silly subcompact (cheaper than a battery by itself) is the most useful tool in the line for sheer portability.
I also picked up the LED flashlight (it's powerful) and the USB/car-adapter socket charging unit that lets you use your m12 batteries as backups for other small electronics.
Milwaukee just put out a 3/8" drill with variable speed to cover more demanding drilling tasks that I'm considering but subcompact + corded drills for 'real' drilling seems to be covering my needs just fine for now.
I'm guessing the Bosch, Makita and Ridgid versions of these tools are all quite good but Bosch and Milwaukee seem to have the most competitive lineup for sheer variety. I'd really like to get my hands on that Bosch cutout tool to see what it's capable of and I'm surprised Milwaukee didn't put out it's own.
The Milwaukee tools are a combination of plastic, a surprising amount of metal and nice rubberized grips in all the right places. They don't inspire the same confidence as my Milwaukee Magnum hole shooter but I'm sure they can take the occasional drop just fine. I can't compare to other brands from experience but it sounds like people are pretty happy with these tools across all the decent brands. Ridgid has a nice battery-replacement program worth considering but I'm not expecting to need that for my Milwaukee batteries.
