I'd like to give this combo 5 stars, but it has a few minuses that knock it down a star.
br /
br /First the positives:
br /- The drill is very nice. It has good power and good balance. The belt hook works fine, can be set to hang on the left or the right, and if you don't like it you can take it off.
br /- The saw is good. It has a LH blade which is great for us right-handers. Its 61/2" blade lets you cut 2X lumber at 45 degrees.
br /- The light is really nice. The little LED turns on when the battery get too low to keep the florescent bulb lit, and the LED give you enough light to change the battery. Its handle can be set to several angles and it will hang over large pipes. This light is also great for camping.
br /- The recip saw works fine. Plenty of power to do the kind of rough, hack it up kinda cuts you make with a recip saw. The blade chuck holds the blades securely yet you can change blades quickly.
br /- The bag is even good. It's very heavy duty with plenty of room to store this kit with room left over.
br /
br /Now, the negatives:
br /- Unlike most other Hitachi 61/2" saws, this one does not have a built-in light. The light is a really nice feature of other Hitachi saws that you don't think you need until you have it.
br /- The drill's belt clip lacks a light; other Hitachi drills have a light in their belt clip.
br /- The charger included with this kit is not as good as some of the other Hitachi chargers. It charges the batteries fast enough (40 minutes), but for some reason the batteries are only rated for 300 cycles when charged by the UC18YG charger included in this kit, vs 1000 cycles when charged with the UC24YFA or UC24YJ chargers.
br /
br /I've been reading a lot of Hitachi reviews that have said the batteries won't hold a charge. I have 10 Hitachi batteries: 3 are the 3AHr NiMH batteries and 7 are the 2AHr NiCads. They all seem to hold a charge just fine. The flashlight in this kit is great for discharging the batteries all the way before recharging. A battery will still light the flashlight quite a while after the battery seems to be "dead" in one of the tools.
br /
br /In conclusion, it's a good kit, and a good value. Hitachi dropped a few features with the tools in this kit to save some bucks.

I haven't purchased a cordless tool in almost 15 years because the Makita 9.6v 6012HD would not die! However, I've started a kitchen renovation project and now was the time to upgrade. I purchased the Hitachi KC 18 DVF because of the overall value of the items included. The drill and the circulating saw have been used the most since this project started and have performed admirably. After several drain and recharge cycles, the NiCad batteries are performing better then expected in spite of the less then glowing assessments printed here. NiCad batteries do require a "breaking in" period when new and if you follow proper charging etiquette, you will get good performance from them. I would recommend this kit to any serious, home DIY that needs a good quality cordless tool with a budget in mind.

I am a remodeling contractor and own toold from virtually every major manufacturer. This was my first multi-tool kit purchase, and it has been worth every penny.
br /The drill is an excellent workhorse that has plenty of power. The circular saw has amazed me with its power and quiet operation. The recip saw does such a good job that I have almost completely retired my Dewalt corded model.
br /The only complaint I have about the entire kit is the light. It does a poor job of general illumination and spotlight mode. The flashlight Hitachi includes in some of their other drill kits is far better.

My Hitachi set surprised me with it's power to weight ratio. I've owned just about every Brand of cordless tools. Although it has only been a few weeks, I've tested each tool thoroughly.
br / 1. The drill: Awesome power and torque with excellent battery time. The one down-side I have found is the comfort of the grip. After several hours of use the top of the grip seems to wear on the spot right between my index finger and thumb more than any other drill. I would still buy this drill again.
br / 2. Circular saw: Cuts through everything. Solid Doors, P/T Wood, Vinyl window frames and solid oak flooring. The saw itself is lightweight and quiet. The noise produced is almost similar to my son's toy saw.
br / 3. Tiger saw: Plenty of power and a decent battery life. I haven't had any problems with the quick-change blade release. After 30 or so blade changes, the adapter seems to be holding up well. The safety lock is a little annoying at first, but once I was used to it I stopped squeezing the trigger and checking the battery connection.
br / 4. The lantern: As described, it's a lantern. It is not a flashlight or spot light. The unit's shape is a little awkward and it does provide general room lighting, I do not carry it around to Job sites. I would bring it camping though.
br /
br /Overall, I was impressed with the set. Several other contractors I work with have tried the tools and they are already looking to purchase the same set.

With the exception of the low cycle count for battery use, this set constitutes a fantastic value for the entry- to mid-level user.
br /
br /The set is fantastic, light weight and user friendly.
br /
br /In the end, this set is addictive and you will look forward to every opportunity to use it.

I will start by saying I have always liked Hitachi tools and after buying the 18V impact driver last summer, I decided to give this set a try. The price was right and I needed a new set of tools so I figured why not!
br /
br /I'll tell you why not...
br /
br /The sawzall is bulky, clumsy and woefully underpowered. It rattles like it is vibrating all the screws right out of it and just overall is not the least bit pleasant to use.
br /
br /The circular saw is decent but has an awkward safety to engage the trigger that I don't like even a little bit. This saw, like the sawzall just seems really underpowered for 18V but as long as you have relatively fresh blades in both, they will get the job done. Just don't believe all that junk all the cordless tool companies tell you about cutting 98 2x4's on a single charge, it just won't ever happen unless you change the blade 98 times I suppose....
br /
br /Last is the drill. What an absolute disgrace this thing is. After owning maybe a dozen cordless drills in my lifetime, this was the single biggest disappointment. I have never had this particular thing happen on a drill of any kind before but the drill chuck actually stripped the screw that retains it and the chuck came off the drill. This is absolutely unacceptable, I've only had this set for 2 months and I absolutely hate it. If I could return it I would.The drill also gets exceptionally hot when used for extended periods which I find to be troublesome because I mean almost too hot to hold anymore which is just lame in my opinion.
br /
br / As it stands I will probably give the whole set away without the batteries which I'll keep for the impact gun and move on to another brand, most likely bosch.
br /
br /Avoid this set like the plague unless you are only going to use it once a year for light work. Certainly not the quality I've come to expect from this company over the years....
br /
br /
br /UPDATE
br /
br /It's now October. I've had the set since June.
br /
br /Today the cordless drill has died. Thought the battery needed replacement, it won't come out. After 15 minutes of wrestling with this piece of junk I get the battery out and put in a new one. Drill is dead. Please people, don't consider buying this set, there is not one redeeming quality in this set. Think about it this way. If this were truly a 4 pc. Lithium Ion cordless set worth anything at all, wouldn't it cost more then $210????
br /
br /Save your money, dump Hitachi

I'm surprised by the negative reviews. I like many other bought this set
br /as a factory refurb with 2Ah batteries for ~net $125 a couple of years ago.
br /
br /I have been so pleased with the drill's balance and power I have purchased 6 more for work and home.
br /Don't expect anyones reciprocating saw or circular saw to run long on batteries, they just suck juice.
br /
br /I have recommended the set as well at $250+/- and the purchaser is still pleased with it.
br /
br /At the current (Oct 2008) price of $210 this represents a very good value.

let me start by saying that i am a big fan of hitachi. my miter saw is a 10" hitachi, i use a hitachi framing gun and compressor and my corded drill is a hitachi. i just bought the combo kit on saturday and used it for the first time yesterday (monday) at work.
br /i burned out the drill the first time i used it. i was drilling an 11/16" hole through a 4x8 beam and the drill started smoking and now it doesn't work. my porter cable 19.2 volt has no problem drilling like that so i didn't think it would be a problem with the 18 volt hitachi. i was pretty upset about that but i figure i'll just keep using my 19.2v porter cable for a drill.
br /the sawzall and the circ. saw are awesome. i used them all day yesterday. i was cutting through 5/8", 3/4" and 7/8" steel allthread with the sawzall and it worked great. the circ. saw was cutting osb, and 2x6's and also worked great. what i plan on doing is buying a lithium ion impact driver and using the batteries for this whole set which is the coolest thing about the hitachi's cordless tools.

This was my second purchase of Hitachi cordless tools. One of the decision points for me was the handle design. For me, they are very comfortable in the hand.

I still have the 9.6 volt drill I purchased over 15 years ago. It has fallen off buidings, kicked around, bounced about in the back of my truck. Still runs fine. Compound miter saws used day in and day out for years, still cut true. I can see the same contrator quality is here at an unreal price.

Stay clear of this product and ANY tools for that matter from Amazon. You would think this product would be worth while, its description seems "heavy duty" yet when I bought it - the batteries would only last 1 hour or less, would not charge - and could barley install a screw to support a picture. When I tried to return it to Amazon - they wouldn't even refund the whole amount of my purchase despite its uselessness. Extremely disappointing for Amazon not to stand up to their product(s). When I called to discuss this with a rep - she told me that the batteries should only last an hour. What kind of cordless tool only lasts "an hour"?? Can you imagine trying to get something done - clearly, they can't comprehend this. Stay away from this cordless tool - and if your trying to save a few bucks on your renovation, or working on you new 1-yr old's crib you designed and want to build yourself - Look at Dewalt's products...then purchase them somewhere else other than Amazon. If the product doesn't work - they won't stand behind it and you've just donated to their cause.
