DeWalt DCS391 20-Volt MAX Li-Ion Circular Saw

DeWalt released a new and remastered line of 20V MAX cordless power tools in 2011. The new line consists of 11 tools and a number of combo kits. In the 20V Max lineup, there are DCD780C2 compact drill-driver kit, DCF885C2 compact 1/4″ impact driver kit, DCD740C1 compact angle drill kit, DCS380L1 reciprocating saw kit and DCS391L1 6-1/2″ circular saw kit. The DCS391L1 kit includes the DeWalt DCS391 that can be a great choice for anyone looking for a well balanced and light battery operated circular saw. As of this writing, the DCS391B, the bare tool version, is the best selling item in the power circular saw category on Amazon.

With the latest lithium-ion battery technology, 18-volt circular saws today are incredibly flexible and versatile. Li-ion batteries have many advantages over Ni-Cad and NiMH. 18V Li-ion power tools are lighter in weight but pack the power of their corded cousins. The new line of DeWalt 20V Max Tools, while are based off the 18V platform, come with some improvements. The nominal voltage is still 18V. There is no voltage difference between 18v and 20V batteries. But the new slide-on battery design allows for a more ergonomic grip. The 20V line has the electronics in the tool, not in the battery. The DCS391 itself comes with a rubber overmolded comfort grip to deliver optimal balance and control.

The DeWalt DCS391L1 comes with one 20V MAX 3.0 Ah lithium-ion battery. DeWalt claims that the new battery provides up to 57 percent more runtime than leading 18-volt lithium-ion tools. The DeWalt DCS391M1 circular saw kit comes with one 20V MAX XR premium 4.0 Ah Li-Ion battery that provides up to 33% longer run-time than the standard 20V MAX battery packs. It weighs merely 1.42 lbs and features a 3-LED fuel gauge system. Purchased separately, 4.0 Ah DCB204 XR premium 2-pack costs around $100. It charges in about 70 minutes. Of course, if you already own some Dewalt 20V MAX battery packs, buying the DCS391B is perhaps the best route to take.

When it comes to circular saws, the faster the blade spins, the better the cut in terms of control. The motor of this saw has a top RPM of 3700 RPM which is standard for 18 Volt 6-1/2” circ saws. Some top rated models such as the Porter-Cable PC18CSL and the Makita BSS610 are also rated at 3700 RPM. Although it does not deliver the fastest cutting speed in its class, many people have been pleased with its performance. Powered by a 460 MWO motor, the DCS391 has been advertised to be 10 percent more powerful than previous DEWALT 6.5-inch cordless circular saws.

DeWalt DCS391 Magnesium Shoe

Of course, RPM is not the only deciding factor when shopping for a circular saw. This handheld power saw has a maximum cutting depth of 2.25 inches at 90 degrees. It cuts up to 1-5/8″ depth at 45 degrees. The full range of the bevel adjustment is from 0° to 50°. You can modify your cut angle in one degree increments. Located on the front of the saw show, there is a kerf indicator to help you guide the saw along cutting lines. When it comes to safety features, the blade stops when you release the trigger, which is a very nice feature. It is also required to release the trigger switch lock-off button before you can pull the trigger switch to turn the motor on.

The DeWalt 20v Lithium Ion power tool has received a lot of encouraging feedback from its customers at Amazon.com. People have commented on how light it is. This saw offers a lightweight magnesium shoe. It certainly is not perfect. Some have reported that it uses batteries pretty quickly. If you buy the bare tool version, consider to get the high capacity 4Ah or 5Ah battery. Furthermore, the package lacks of a rip fence. This should be included in the box. Other negative reviews have been made in relation to the plastic guard. .It would be better if it was made of metal. The fact the the blade is on the left of motor might also bother some people. However, if you are left handed you will be happy with this design.

Despite some minor considerations, the customers have found the battery operated circular saw to be very powerful. While it is not in competition with corded versions, it easily cuts through 2×4. It cuts 3/4″ plywood pieces without issue. The customers have also been impressed with the quality and ease of use. According to them, the saw is comfortable to hold. Coming with an open concept, it also offers a very easy blade change solution, which is an important factor for serious users. The settings are easy to see and set.

The DeWalt DCS391 seems to have satisfied many of those who purchased it. The compact, cordless power tool may be bit pricey as a single tool but for many people it is worth every penny. As with many other things, you get what you pay for.
