Amazon.com Review

If you're looking for a circular saw that's convenient and easy to use above all else, DeWalt's 8-volt, 6-1/2-inch circular model is a smart choice. This saw features an alloy steel base plate, a bevel adjustment that goes to 50 degrees and can be recalibrated, and a depth-of-cut adjustment that reaches all the way to the blade. It easily cuts two-by material at a 45-degree bevel in a single pass, and has a left-side blade that adds visibility. We especially liked the blade-changing mechanism--the shaft-lock button is easy to find and depress, and the hex key stores on the body of the saw, making the blade easy to switch out and replace. This model also has a powerful fan-cooled motor with replaceable brushes that reach 3,700 rpm. The result is a saw that can cut 35 feet per minute of 1/2-inch plywood. It weighs only 8.4 pounds, and--without a cord to hassle with--you'll find that nothing is easier to haul around on a job site. A cordless saw is a serious timesaver, especially for smaller jobs, when dealing with a cord can be a real hassle. This kit comes with a T-guide; a 16-tooth, 6-1/2-inch blade; and a plastic carrying case. --Jonathon Tudor

3.0 out of 5 stars weak-...batteries, October 26, 2000

This review is from: DEWALT DW939K 18 Volt 6-1/2-Inch Cordless Circular Saw Kit (Tools & Home Improvement)

I bought this... about a week ago. I exchanged a similar Porter-cable l9.2v cordless saw because it seemed that the batteries didnt last as long as they should (the manufacturer touted l24 2X4's)... I exchanged it for the Dewalt saw. The 18v Dewalt's batteries don't last any longer than the Porter Cable's l9.2v, but the Porter Cable had more power. I am not impressed with the tool. Manufactures claims on tool-company web sites claim this saw can cut 125-175 2X4's on a single charge. NO WAY!!!

4.0 out of 5 stars DeWalt DW939K 18-Volt 6-1/2" Cordless Circular Saw Kit, July 30, 2002

By A Customer

This review is from: DEWALT DW939K 18 Volt 6-1/2-Inch Cordless Circular Saw Kit (Tools & Home Improvement)

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.

4.0 out of 5 stars Cordless isn't acceptable for occassional use, December 2, 2002

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.
