DONT BUY CHEAP BATTERIES!!!!
The DeWalt saw DC390B is one tough little saw! I have owned this saw for several years before my last one met its untimely demise from being thrown from a 3 story roof to the street below, and it wasn’t the saws fault by no means, I had bought some cheap replacement batteries from amazon, (URPOWER® 2 Pack 18V Battery for DEWALT) and after the 4-5th time the battery pack fell out of the saw from trying to cut the same 2×6 rafter the whole dang unit went flying, so I had to buy another saw and REAL DeWalt Battery packs. But, with that being said, my previous saw which is the very same saw has been VERY dependable for 5 days a week, 45 weeks a year and for 3 years straight before I had to replace the batteries and if it wasn’t for my little outburst, the saw would have still been going today if I didn’t buy cheap crappy batteries. But it was looking rough and was needing to be replaced, but it still cut straight and true and has never gave me a minute of trouble! Just like I hope this new one does!!!
I used it for 5 minutes. Worked flawlessly
Consider Dewalt Please
I bought the first Dewalt 18 volt set in 2004. I gave the original one to my grandson for his construction business. It is still working but is getting tired. I replaced it with a new one this year 2018. The original one was used for crosscut and rip on lumber up to and including 2×12, hardie plank, and steel roofing. It is a very friendly tool on the roof, crawl spaces, and rafters. The saw is very robust as well. We have dropped it more than once from a roof and rafter location. I have a worm drive Makita that is a great saw as well but it has seen most of it duty diminished due to the convince of the Dewalt unit. The Makita saw is a great framing and large construction saw. Dewalt 18 volt cordless tools have expedited our output on many projects. We have used other cordless tools as well but in my opinion the broad range of tools that Dewalt has to offer in the 18 volt line is very useful. The real consumer friendly thing that Dewalt did was supporting the 18 to 20 volt upgrade with a adapter for most of the older lines. This is very business friendly because it allow an upgrade to occur as the older units need replaced instead of the large bit for a new line. Thanks Dewalt.
I bought this saw to use primarily for ‘breaking down’ large heavy sheet goods while they are on my trailer before hauling the pieces into my wood shop for final cutting and fitting. It is far easier to move a quarter or third of a sheet of 7/8″ plywood single handed than a whole sheet, especially in a cramped shop with a low ceiling. I wasn’t really expecting the saw to do more than that but I can say now that it is fully up to normal remodeling service with the stock blade it delivers with. With the DC9180 battery (the ‘heavy’ one) it is a third the weight of my old lightweight Craftsman circular saw an probably a sixth the weight of my heavy worm-drive Milwaukee. While it certainly doesn’t have the power of either of these it easily cuts 3/4″ plywood (I’ve ripped several sheets lengthwise already) and regular 2-by framing lumber and this is probably all any home user will ever need to do. I do recommend that you use it with the DC9180 battery rather than the lighter DC9181 for the extra run time although it will run on the latter. For me, the hardest thing to get used to is the lack of a cord since I have always been paranoid about the cord on my other saws getting in the way or getting hung up on the work.
Just what I was wanting
I had a 14.4 V Dewalt circular saw for years, and used the snot out of it. It was just the thing to make a cut or two on a roof, or while remodeling when you had to have the power turned off in that area of the house. Eventually, I made the change to 18V tools, and when my last 14.4 battery died, it was cheaper to buy this saw, than 2 replacement 14.4 batteries.
This little saw came in very handy when we put …
This little saw came in very handy when we put a new roof on the house. We eliminated the old style vents and this worked well to cut out to patch in new decking and to cut the new ridge vent. Cordless is the way to go on the roof. This tool operated as expected and my husband appreciated the gift
Used it with old batteries from my drill. Works great. Have to have a charger handy though. Shoot, as good as the old 18 volt stuff works I see no need to spend a bunch money for all the new 21 v stuff and new battery technology. Just have a charger handy and you’re golden. Inverter in the truck works just fine when away from a power source.
Pretty good for what it is
I just got this saw and used it to make some shelves. All circular saws I’ve owned in the past were corded. I had used other cordless circular saws before and was disappointed, but I can say this one was good enough to get the job done. I would recommend it to someone who is doing small jobs, or if portability and cordless capability are extremely important.
Very Good Value
I bought this unit as a “bare-tool” saw because I ordered a Dewalt drill with two batteries and a charger. Turns out that was a good move because those batteries hold a charge and recharge very fast. I worked all day using both the saw and driver on a single charge.
