3inch Brushless Circular Saw

[Set name: For Dewalt]
First impression is that it is a nice tool. Dewalt battery fit is on the snug side and varies depending on the particular genuine Dewalt battery, but particularly tight with my brand new 3Ah DCB230 battery. Tight enough so both installation and removal are difficult. I have not tried any third party batteries yet. Battery power indicator reads slightly variable and low with freshly charged batteries, though in the ballpark at least. The two noted items are why the review is 4 stars rather than 5. If any performance problems noted I will revise this review.

Smooth operation. Good balance.

Tremendous Bang for your buckemsDT

A very handy addition to the DIY'ers tool collection. Solid tool and much less expensive than the name brand.

Powerful, was able to cut 8 bolts off my trailer bunk board with no problem plenty of power and still had juice left on battery

I just received this. So far I really like it.I needed a backup for my Milwaukee M12 cutoff tool, which I use the heck out of, but couldn’t bring myself to cough up another $150 when this one was $60 and uses the M18 batteries- which I have plenty of.It’s actually better than the M12 in that it has a variable speed trigger. Press harder=spin faster. The motor seems powerful and gets up to speed instantly, actually faster than the Milwaukee. It’s got forward and reverse with a center switch that also locks out the trigger. The M12 has the same, and that lockout capability is essential. Twice I’ve forgotten to lock my M12 before putting it in my carpenters bags and had the trigger get depressed randomly with the blade trying to cut through both the bags and me. So yeah, remember to lock it.The tool seems well-made, time will tell how durable it is. It’s larger than the M12 but you’d expect that as it takes the M18 batteries.It comes with a set of cutoff wheels for different materials, wood, plastic, steel, and probably concrete. The wood blade in particular looks legit, it appears to have carbide teeth. I’m looking forward to trying it out.

Up for review is the Demima Cut-off tool for the Dewalt battery system. Despite the tool's physical small size of the motor, I found it to have more than enough power cut through thin metal and several types of ceramic and marble tiles. Ergonomically, it fits well in the hand and is relatively light weight depending on the Amp-hour of the battery installed. There is a depth of cut a little over 1/2" before the machine's motor housing contacts the work-piece. After all, it is a relatively small wheel at just 3".There are two issues that my unit has - one is just annoying and the other more serious. The annoying issue is that of the 9 different batteries that I tried and were charged from 4 different chargers, the battery meter at most read only 83%. All batteries were fresh off the chargers and the internal battery level LED's showed full charge on all. I believe that the tool's battery charge indicator is not reading correctly. An annoying issue as I always just check the battery's charge indicator when I think it is getting low on charge anyway. It would be nice, since the engineer took the time to design the tool with a battery level indicator,that it be reasonably accurate. Just an annoyance.The second issue that is much more serious is the battery fit into the tool. The last 1/4" to 1/2" of travel when installing the battery is extremely tight, requiring considerably more force to fully seat than it should. Worse is battery removal. Once you get it installed, you almost need to pry it out. It seems to get wedged in there. I tried this with the 9 batteries mentioned above. These were a combination of genuine Dewalt OEM and several brands of third party batteries. All fit the same - poorly. I can not find any wear or scuff marks on the battery socket that would allow me to machine a little bit of clearance. So far, multiple insertion of the batteries has not loosened this up at all. It may be something that I will have to live with unless I can identify the problem area.The tool works well and seems to be up to the task for which it was created. However, having to fight it to get a battery in or (even worse) removed lessens its appeal to me. Due to the battery fit, and to a lesser degree the worthless battery level display, I'm giving this a 3 star rating. Would I recommend it to a friend? Probably not, at least not without the battery fit caveat.

I’m still trying to figure out the main use for this tool. The product description page calls it a cut off tool, but the instruction booklet calls it an angle grinder. There is a photo on the description page showing them cutting what looks to be a 3/4” thick board, which is very strange and deceptive, because the blade probably can’t cut that deep and there is no baseplate to keep the blade 90 degrees to the board, and I don’t think the 3” blade could cut more than a half inch deep. The instructions don’t specify this. The instructions are basically useless, they don’t really describe the tool well or how to use it, just how to install the blades and some repeated safety instructions that seem so generic that they were copied from some other source that didn’t fit this tool.When the motor is running, a distinctive for is produced that reminds me of older tools with motor brushes since I just received this tool, I don’t know if that “electrical” smell will diminish over time with repeated use.The display shows numbers while the motor is running that are supposed to indicate the percent of battery charge left. However, the numbers constantly jump around between 98% and about 70% with a mostly full battery. I don’t know what is causing this wide fluctuation in numbers, but I rely on the LEDs on the actual battery to approximate the state of charge since the displayed numbers on the tool are jumping around erratically.I think that without a baseplate to standardize the cutting angle, the types of materials that can be safe cut are limited, since hand holding this can’t maintain a consistent angle and the blades might be damaged if your hand wobbles.Probably okay for thin stuff like plastic pipe or thin panels.The LED light is useful. An Allen wris included for changing the blade, and it snaps into the tool for storage.There are two grinding cutoff disks included that are similar to ones you might use with a traditional angle grinder or cut off tool. They are thin, so they cut a thin kerf and don’t waste material, but have the potential to break. There is a diamond grit encrusted metal cutting blade and a wood cutting blade with tungsten carbide teeth.The box contained safe Goggles and lightweight gloves.My Dewalt batteries fit well and operated the tool competently.The blade direction is reversible, but I’m not sure when this would be used, since the wood cutting blade can only be used with the blade spinning in the correct direction to make the teeth engage the wood.The handle is non-slip and comfortable.I hope the odor doesn’t indicate something bad is happening internally.The nearly useless instructions, erratic state of charge display, odor, and lack of s baseboard for consistent cutting angle are concerns, but still the tool has uses when a circular saw is too big to use or when a small cut off is needed. It seems that the manufacturer can’t decide this is a cut off saw or an angle grinder. Still, it’s single hand use and light weight make it useful for jobs when a big angle grinder or circular saw won’t fit.
