When you dig into the sales data, it is obvious why the DeWalt 20V MAX DCS391B is dominating the market right now.
Buyers are prioritizing tools that are easy to control without sacrificing power. This model features a highly efficient motor that spins at 5,150 RPM. This gives you the speed necessary to make incredibly demanding cuts through lumber and sheet goods without the motor bogging down.
The biggest structural advantage of this saw is the base plate. Instead of cheap stamped aluminum, DeWalt upgraded this model with a high strength and lightweight magnesium shoe.
In our experience, magnesium is the exact material you want for jobsite durability and long term cut accuracy. It survives drops that would ruin lesser tools.
It also features an optimized rubber over molded comfort grip, which provides exceptional balance and control when you are working long hours. Finally, the 0 to 50 degree bevel capacity allows you to tackle aggressive angled cuts for a huge variety of framing applications.
What Buyers Love
Based on extensive feedback from verified users who use this saw daily, here is where the DCS391B truly excels:
Exceptional Portability and Weight: Users consistently praise how light and easy to maneuver this saw is compared to traditional corded models. One veteran contractor noted that the reduced weight drastically cuts down on the fatigue associated with using a saw all day long.
Smooth and Capable Power: Despite being battery powered, buyers report that the motor is smooth as silk and easily tears through solid oak and maple. It handles standard 2×4 cuts with ease.
Instant Safety Brake: A major highlight for users is the integrated blade brake. Multiple reviewers noted how much they appreciate that the blade stops spinning within seconds of releasing the trigger, adding a massive layer of safety and speed to the workflow.
Superior Line of Sight: Because the blade is positioned on the left side of the motor, right handed operators have a direct and unobstructed view of the cutting line and the work surface.
POTENTIAL DRAWBACKS
While the portability is fantastic, digging into the critical performance data reveals a few glaring issues that you must consider before purchasing. This saw is not built for heavy or continuous ripping.
Motor Stalling Under Load: The most common failure point reported by users is that the motor repeatedly shuts down when pushed. Reviewers noted the saw bogs down and stops completely when cutting through solid core doors, ripping 2x4s, or even cutting thin hardboard.
Severe Battery Drain: This tool requires a massive amount of energy to operate. Multiple users reported that the saw drains fully charged batteries extremely quickly. To get all day performance, you must invest in the high capacity 4.0Ah or 5.0Ah batteries.
Build Quality Concerns: While the main shoe is cast from high quality magnesium, some users expressed disappointment that the blade guard is made of plastic. This can feel cheap for a professional grade brand and may be prone to cracking over time.
Warranty and Repair Headaches: If your saw breaks after the initial return window, the manufacturer warranty process can be very difficult. One buyer reported that repairing the saw under the three year warranty cost $89 in service fees, making the repair almost as expensive as buying a brand new bare tool.
If you are climbing ladders or making repetitive cuts all day, saving a few pounds of weight can save your shoulder. The data shows buyers are flocking to the Makita 18V LXT XSS02Z for exactly this reason.
Our analysis reveals that this saw weighs an incredibly light 7.3 pounds, and that includes the weight of the battery.
Makita is legendary for their motor engineering and ergonomics. This model features a specialized flat motor housing. This might sound like a minor detail, but it provides excellent stability when you lay the saw on its side to change the blade.
It also utilizes a precision machined aluminum base to ensure your cuts remain smooth and accurate. Combined with the rubberized soft grip handle, this saw is built to drastically reduce operator fatigue on long job site days. Despite the smaller 6-1/2 inch blade, it still delivers a solid 2-1/4 inch cutting capacity at a 90 degree angle.
What Buyers Love
Diving deep into the expanded verified customer data reinforces our initial findings and adds some serious weight to this tool’s capability:
Extreme Lightweight Control: Buyers repeatedly highlight the massive ergonomic advantage of this tool. Users noted that upgrading to this lightweight model from heavy 15 amp corded saws completely eliminated their daily shoulder fatigue. It is so well balanced that users frequently praise how easy it is to operate one handed.
Surprising Raw Power: Do not let the brushed motor or the lightweight frame fool you. Veteran woodworkers report that this saw easily rips through rough sawn hardwoods up to 2 inches thick without any blade wobble.
Dead On Accuracy: Users report the saw cuts perfectly square right out of the box. One former tool dealer noted that the cuts are so clean and straight on rough lumber that they rarely even need to use an edge jointer afterwards.
Optimized Battery Efficiency: Even though this model uses a traditional brushed motor, the power draw is highly efficient. Field reports show the saw runs for a surprisingly long time on a smaller 3Ah battery.
Proven Long Term Reliability: This saw has a massive track record of survival. Multiple users report relying on this exact model for years, with one reviewer confirming their saw is still cutting like new after 7 years of heavy use.
POTENTIAL DRAWBACKS
While the ergonomics are world class, diving into the critical performance data reveals several hidden flaws that you must consider before making a purchase.
Severe Power Limitations: The most common mechanical failure point reported by users is a severe lack of torque when cutting anything thicker than standard plywood. Pushing the tool through tough cuts causes it to overheat quickly and drain high capacity batteries much faster than expected.
Tracking and Accuracy Struggles: When the motor is pushed to its limit, the saw has a tendency to wander. Multiple users reported that the blade drifts away from straight edge guide rails during long cuts.
Packaging and Quality Control Red Flags: A massive portion of the negative data points directly to third party shipping and inventory control. Many buyers received their saw wrapped only in bubble wrap without the original manufacturer box or manuals.
Blade Orientation Concerns: This saw is built with a left side blade design. While this gives right handed users a great view of the cut line, several buyers found the weight distribution awkward and potentially dangerous at the end of a cut.
Repair and Warranty Headaches: Users reported that when the saw does break, getting it repaired is a nightmare. Repairing this specific model can take months and often costs more than simply buying a new bare tool.
Not everyone needs a heavy duty framing saw to build a simple backyard birdhouse or cut a few pieces of trim. The sales data proves that for weekend warriors, the highly compact Ryobi 18V ONE+ P505 is the absolute best value on the market.
This saw is incredibly small, weighing in at an ultra-light 5.3 pounds bare. This makes it exceptionally easy to control for beginners who might be intimidated by heavier professional saws.
Despite its small footprint, the motor still spins at a respectable 4,700 RPM. Ryobi also included a few very smart design features specifically geared toward DIY safety and control.
It utilizes a transparent polyurethane lower blade guard, giving you maximum visibility on your work surface while you make your cuts. Furthermore, the handle features their Gripzone rubber overmold to increase friction and improve your grip, while an extra side handle on the left side ensures you can safely operate the tool with two hands.
What Buyers Love
Digging into the verified customer feedback reveals exactly why this ultra compact saw is flying off the shelves:
Unbeatable Lightweight Handling: The weight is the star of the show here. Buyers consistently rave about how easy this 5.3 pound saw is to maneuver. Users with smaller hands or those who fatigue easily note that the grip placement and low weight make it perfectly balanced and safe to use.
Punching Above Its Weight Class: Despite the small 5-1/2 inch blade, users report being shocked by its actual cutting power. Reviewers note it easily breezes through thick butcher block countertops, dense maple, and heavy 3/4 inch plywood without stalling.
Superior Cut Visibility: Because this saw positions the blade on the left side of the motor, right handed users have an incredibly clear and direct line of sight to their cut marks.
Massive Battery Flexibility: A huge selling point for buyers is how long this efficient little motor runs on a single charge. Because it uses the universal Ryobi ONE+ system, users love that they can swap batteries seamlessly between this saw, their drill, and even their yard tools.
Incredible Value: Multiple users point out that for small, casual jobs, spending professional level money is totally unnecessary. At a sub $50 price point, buyers consider this saw one of the best investments they have made for weekend house projects.
POTENTIAL DRAWBACKS
While the price tag is incredibly appealing, digging into the critical performance data reveals that this saw has a very strict ceiling. If you push this tool beyond light hobbyist work, it will fail.
-
Severe Motor Burnout Risks: The most glaring issue in the data is catastrophic motor failure. Multiple users reported that the motor began smoking, smelling like burning plastic, or completely dying when trying to rip thicker materials like treated 2x4s or hollow core doors.
-
Packaging and Quality Control Red Flags: Numerous buyers reported receiving their saw wrapped only in a plastic bag or a plain brown box with no manual included. Many users suspected they were shipped a used or refurbished item instead of a brand new tool.
-
Missing Critical Hardware: Hand in hand with the poor packaging, several buyers could not even use their saw out of the box because it arrived missing vital components like depth adjustment knobs, bevel lock bolts, washers, and even the included saw blade.
-
Frustrating Design Flaws: The 5-1/2 inch blade inherently limits your cutting depth, making standard 2×4 cuts very tight. Furthermore, users pointed out a frustrating design flaw with the depth adjustment mechanism itself, noting the tightening screw is too short and easily falls out.
-
Warranty Void Risks: Ryobi is very strict about authorized retailers. Buyers noted that purchasing this bare tool from unauthorized third party sellers online meant that Ryobi refused to honor their manufacturer warranty when the motor inevitably burned out.
Buyers Guide
Before you spend your money on any circular saw, you need to understand the core features that dictate performance. Making an educated choice ensures you get the right tool for your specific needs. Keep these key points in mind before you buy.
Blade Guard and Safety Mechanisms Your safety is the absolute priority. Always look for a saw that has a smooth operating lower blade guard. Cheaper saws often have sticky guards that snag on the edge of the wood when you start a cut. This can force you to manually pull the guard back, which is incredibly dangerous. Additionally, always look for models with an electric brake. An electric brake stops the spinning blade in less than two seconds after you let go of the trigger, drastically reducing the risk of accidental cuts when you set the tool down.
Build Quality and Base Materials The base of the saw is called the shoe. The material of the shoe determines the long term accuracy of the tool. Budget tools use stamped aluminum or plastic. These warp easily over time. Professional tools use cast magnesium or thick machined aluminum. Magnesium is lighter than aluminum but significantly stronger. If you plan on using your saw regularly, invest in a model with a premium shoe to ensure your cuts stay perfectly square for years to come.
Power Output and Battery Platforms Cordless technology has taken over the market. When you buy a cordless circular saw, you are not just buying a tool. You are buying into a battery platform. Once you buy a DeWalt battery, it will only work with other DeWalt tools. Choose a brand that makes all the other tools you might want in the future. For power output, a standard 18V or 20V battery is perfect for almost all house work. Just remember that circular saws drain batteries quickly, so you will want to invest in larger 4.0Ah or 5.0Ah battery packs.
Ergonomics and Overall Weight A lighter saw is always easier to control, which makes your cuts straighter and safer. Pay attention to the grip placement. You want a saw with a comfortable primary handle and a sturdy front pommel handle for your second hand. Two hands on the saw means total control and zero chance of your fingers getting near the blade.
