This kit from Makita is the biggest combination kit I've seen. It has 15 different tools in it and while a few are things like lamps and a radio, it has enough solid tools in it for just about any project you can think of. It even includes a leaf blower which is great for cleaning the sawdust out of your workshop too.
The Makita set comes with three different saws, three drills and three impact drivers of different sizes. There’s a right-angle drill, a hammer drill, as well as a screw gun, specifically designed for sinking drywall screws to the right depth.
One really great thing about Makita's cordless tools is that they have the fastest recharge time of anyone. If you're in a rush, you can get your batteries back into the tool in as little as 15 which is about half the time of anyone else. The set comes with two chargers and four 3.0 Ah batteries; high capacity units what some manufacturers call "fat packs”.
Milwaukee's kit isn't quite as big as the Makita one is, but it has less frills. They've only put one work light in it (rather than two), and there's no job site radio taking up space. The kit still has three saws, two impact drivers and two drills, one of which is a right-angle drill. The kit only comes with two batteries and one charger, but they’re the 3.0Ah fat pack batteries, or as Milwaukee calls them, "extended capacity batteries".
Milwaukee Tools has two things going for them in any competition. Number one is that their tools are extraordinarily rugged and no matter what, you can count on these tools to last. The other is these tools always have more torque than the competition. It doesn't matter if you're looking at a drill, a driver or a saw; you'll get more power out of a Milwaukee tool than you will anyone else.
DeWalt has a nine piece kit as well, making it technically the same size as the Milwaukee kit. But, this one is considerably less expensive. They've also taken a slightly different approach to putting their kit together, perhaps providing a little more flexibility. First of all, the drill is a hammer drill, so you get both functions out of one tool. They solve the need for a driver by providing both a hex female drive impact for use with standard bits and a 3/8" drive impact driver.
The same three saws are included in this kit that we found in the Makita and Milwaukee kits. But there are also two high-speed rotary cutters for cutting metals. One is a right-angle grinder/cutter like on the other kits, but the other is a more compact vertical cutting tool which could be used in a number of ways, from a small router to a trimmer; I like that extra flexibility. Like most kits, DeWalt’s DCK955X comes with one charger and two batteries which are 2.0Ah charge.
With this kit from Bosch, we're stepping down to a much smaller combo kit but it's considerably cheaper as well. Nevertheless, Bosch has worked to make it very versatile. The kit consists of a hammer drill, circular saw, reciprocating saw, and also comes with a portable work light. It's nice that they included a hammer drill in the kit, as that gives more flexibility than just a regular drill/driver would. The kit comes with two fat pack batteries and a charger, to keep you working nonstop.
Black & Decker has upped their standard battery voltage on their Li-Ion batteries to 20 volts, rather than the 18 volts everyone else uses. That gives their tools a little more power to work with as well as easier to get more torque out of them. This kit consists of a drill, circular saw, reciprocating saw and flashlight. It also comes with a charger and two of their 20 volt MAX batteries. I actually have the drill that's in this kit, which I bought because I wanted an inexpensive cordless drill. It’s worked out great for me, hasn’t caused any problems, and provides plenty of power for my needs.
