DeWalt DW939K 18-Volt 6-1/2" Cordless Circular Saw Kit [Posted on 2002-07-30]
I bought the DW939 a couple of years ago and for the type of work I use it for, it can be a real time saver. I use it mainly to crosscut 2X or rip plywood on smaller jobs. It saves a lot of time by not having to lug around an extension cord, a generator on jobs where no power is available or by having to go out to the job and take measurements first, then do the cutting back at the shop.
To be realistic about things though, I wouldn't mothball your heavy-duty corded 7-1/4" saw just yet.
I've used it to cut 4X4 and 4X6 PT posts several times. I only have to flip them over once to finish the cut and the job is done. The battery run time isn't bad when crosscutting 1X and 2X or ½" plywood but DeWalt must do their battery runtime testing under carefully controlled laboratory conditions because as other owners have stated in their reviews, it's not likely your going to get close to their rated number of cuts per charge with the DW939. So definitely, buy a second battery for continuous use. A fresh sharp blade also helps increase battery performance.
Although the bevel capacity is 50 degrees, from my experience, that is one tough cut for this saw to make in anything more than 5/8" plywood. It's seems just to taxing for the little motor.
Overall, even though it is a bit pricey, I would recommend the DW939 as a go between saw. When used within it's limits, it is excellent on smaller jobs when you want to make a few quick cuts without dragging out the extension cord.

Cordless isn't acceptable for occassional use [Posted on 2002-12-03]
The saw is well made and easy to use except for the trigger. I find it difficult to press the safety and the trigger at the same time. Especially when cutting at an odd angle.

I have used it for framing and plywood. The guide is very easy to use and keeps a good straight line. It won't cut completely through a 2x4 at 45 degrees so you'll have to flip the board over and cut from the other side.

However, this is not a saw that is acceptable for occassional use. If the battery is not properly discharged and recharged it will quickly become a doorstop. Ask yourself how often you are really going to use the saw. If it isn't at least once a month then a corded saw would be cheaper. Otherwise you'll be replacing the battery.

Good worker. [Posted on 2003-05-05]
I have been cutting 2x8s and it does a great job. Especially nice is being able to cut thru the 2*8 at a 45 angel. The blade lock makes changing the blade easy.

The safety latch seems a bit awkward. One has to push the button in before pulling the trigger. For me, the button is in the wrong place and would be easier to push down rather than in. But this is a minor problem.

I haven't used the saw enough to stress test the battery

I love this saw! [Posted on 2004-10-29]
I bought this saw to cut down sheets of plywood before bringing them into the bsmt where there is a table saw. I've had no problem with the battery and love the freedom of throwing it into the back of a vehicle in case wood at the lumberyard is too long. It's weight makes it easy to handle and while I can see an extra battery might be nice, it's been a joy to use.

GREAT SAW !!!! Now my professional contractor friends want one!!! [Posted on 2006-04-29]
Some friends and I, one of which works for PORTER CABLE, a couple of contractors and myself went to build a wheelchair ramp as a church project for an elderly couple. The guys laughed at me when I showed up with my Dewalt DW939 saw. About an hour into our work the power went out in their neighborhood. I handed my saw to the professional contractor that was doing all the cutting and he used it and said it cut smoother than his milwalkie 7 1\4" corded. We did the whole ramp and only had to replace the battery toward the end. Both of the contractors and the guy from Porter Cable all said that they were going to get one ASAP!! My DW939 saved the day!!!
My only complaint was fixed in the DC930 and that was the ergonomics of the handle. the DW939 is fine if you are cutting short distances but when cutting across a 4x8 sheet it is hard to hold your hand parallel to the cutting surface.
