DEWALT 20V MAX XR Brushless 7-1/4-Inch Circular Saw: Best for Tougher Cuts
This is the most powerful saw in the group by its listed output, with a brushless motor rated for up to 1,700 MWO and a no-load speed of up to 5,500 RPM. Its 7-1/4-inch blade and 2-9/16-inch maximum cut depth at 90° give it more capacity than the smaller-blade options here, which can help when a DIY project calls for cutting thicker material.
The saw also offers a 2-inch cut depth at 45° and an electric brake designed to stop the blade from coasting after you release the trigger. Those features make it a capable choice for varied cuts, though safe handling and waiting for the blade to stop are still important. The claimed cut count per charge is an advertised maximum, not a guarantee; actual runtime depends on the battery and material.
This model is sold as a tool only, so it makes the most sense if you already have compatible DEWALT 20V MAX batteries and a charger. Its larger blade and higher output may be more than a casual repair or occasional shelf project requires. The supplied product information also indicates that availability may be limited, so check the listing before planning a purchase.
Pros:
- Brushless motor with up to 1,700 MWO and 5,500 RPM
- Largest blade and greatest listed 90° cut depth in this group
- Electric brake helps stop blade coasting after trigger release
- Suitable for a wider range of demanding cuts than a compact saw
Cons:
- Battery and charger are not included
- May be more saw than needed for light, occasional DIY work
Verdict: Choose this DEWALT if you need substantial cutting capacity and already own compatible batteries; look at the SKIL kit if you want a more complete setup for basic home projects.
SKIL 20V 6-1/2-Inch Circular Saw: Best Starter Kit for DIY
The SKIL stands out for including a 2.0Ah PWR CORE 20 battery and charger. That makes it a practical starting point if you do not already own a cordless-tool battery system. It is designed for cutting wood around the home, and its 6-1/2-inch blade is a useful middle ground for common DIY tasks without stepping up to the larger DEWALT saw.
A thin-kerf, 24-tooth carbide-tipped blade is intended to make fast, clean cuts, while the saw-line visor helps you follow your cut path. The bevel adjustment covers 0° to 50°, giving you room for angled cuts beyond a simple square cut. The supplied details also describe temperature management in the battery, which is designed to help it stay cool during use.
Its main trade-off is that it has less listed cutting capacity than the 7-1/4-inch DEWALT. For typical home wood-cutting jobs, that may be a reasonable compromise, especially because the package includes the battery and charger. If you already own batteries from another tool brand, check compatibility before choosing this kit.
Pros:
- Includes a 2.0Ah battery and charger
- Bevel adjustment covers 0° to 50°
- Thin-kerf carbide-tipped blade is included
- Saw-line visor helps you track the cut
Cons:
- Smaller blade than the 7-1/4-inch DEWALT models
- Battery capacity is modest compared with what some longer projects may call for
Verdict: For a DIYer who needs a cordless saw, battery, and charger in one package, the SKIL is the clearest all-around starting point in this lineup.
ONEAND 18V 5-1/2-Inch Circular Saw: A Compact Option with Listing Caveats
The product title describes an 18V cordless saw with a 5-1/2-inch blade, making it the smallest-blade option in this comparison. A compact format can be worth considering when your projects involve smaller pieces or you prefer a less substantial saw. However, the supplied information does not give cutting depth, bevel range, motor speed, or other performance details needed to judge its capabilities against the better-documented models.
There is also a notable mismatch in the product data: the title says “ONEAND,” the brand field says RYOBI, and the description refers to Stens replacement parts rather than a circular saw. That makes it difficult to confirm what the listing actually includes or which battery system it uses. The title does say the battery and charger are sold separately, so budget for those if you proceed.
The supplied data indicates that this listing may not be available. Because both the product identity and specifications are unclear, it is difficult to recommend this saw over the SKIL or DEWALT options. Confirm the item name, brand, battery compatibility, and specifications on the listing before buying.
Pros:
- Listed with a compact 5-1/2-inch blade
- Tool-only format may suit someone who already has a compatible battery, if confirmed
- Could be worth investigating for smaller cutting tasks
Cons:
- Supplied brand and product description do not match the saw title
- Key cutting specifications and battery compatibility are unclear
Verdict: Consider this option only after verifying the listing details; for a more straightforward purchase, the SKIL kit or a clearly specified DEWALT model is easier to assess.
DEWALT 20V MAX DCS391B: Best for Existing DEWALT Battery Owners
The DCS391B is a tool-only DEWALT saw with a motor rated at 5,150 RPM. Its high-strength magnesium shoe is designed to keep weight down while providing a durable base for cutting, and the overmolded grip is intended to support balance and control. The listed bevel capacity is 0° to 50°, useful for angled cuts on suitable material.
Compared with the newer brushless DCS590B, this model has a lower listed no-load speed and less detailed cutting-depth information in the supplied product data. It may still make sense if you already use compatible DEWALT 20V MAX batteries and want a simpler saw for regular home projects. Since the battery is not included, it is less convenient as a first cordless tool.
For a buyer starting from scratch, the SKIL package offers a battery and charger. For projects that need the greatest stated cutting depth and output, the DCS590B is the stronger-listed option. The DCS391B sits between those choices, with useful bevel capacity and a lightweight magnesium shoe.
Pros:
- 5,150 RPM motor
- Magnesium shoe is designed to combine low weight with durability
- 0° to 50° bevel capacity
- Overmolded grip is designed for balance and control
Cons:
- Battery and charger are not included
- Supplied details do not list its maximum cutting depth
Verdict: The DCS391B is a sensible candidate if you already own compatible DEWALT batteries and want a bevel-capable saw, but it is not the best-value starting kit for a new cordless-tool setup.
BLACK+DECKER 20V MAX POWERCONNECT Brushless Saw: Best for Compact DIY Work
This 6-1/2-inch BLACK+DECKER uses a brushless motor and reaches up to 4,300 RPM without a load. Its listed maximum cut depth is 2-5/32 inches at 90° and 1-9/16 inches at 45°, with bevel adjustment up to 50°. That provides useful flexibility for common wood-cutting jobs, though its stated depth is less than the larger DEWALT DCS590B.
The saw has an aluminum base plate, a built-in LED to light the work area, and a connection point for a separately sold vacuum or dust bag. The base plate is also described as compatible with a guide rail, which is not included. These details make it a feature-rich option for controlled cuts and work in tighter spaces.
The supplied description states that it can cut up to 102 linear feet or 165 cuts per charge, but actual runtime will depend on the battery, material, and cutting conditions. The product information does not clearly say whether a battery and charger are included, so check the package contents before ordering. It may appeal to people already using the POWERCONNECT battery family, but the SKIL is the more clearly specified kit for first-time buyers.
Pros:
- Brushless motor with up to 4,300 RPM
- Bevel adjustment up to 50° and useful listed cutting depth
- Aluminum base plate and built-in LED
- Can connect to a separately sold dust bag or vacuum
Cons:
- Battery and charger inclusion is not clear in the supplied details
- Guide rail, dust bag, and vacuum are sold separately
Verdict: Choose the BLACK+DECKER if its POWERCONNECT system fits your needs and you value its LED and dust-connection options, but confirm battery contents before checkout.
How to Choose a Cordless Circular Saw for DIY
Match the Blade Size to Your Projects
A larger blade generally gives you more cutting capacity, while a smaller saw can be easier to manage for lighter work. In this group, the 7-1/4-inch DEWALT DCS590B lists the greatest cut depth, while the 6-1/2-inch models offer a practical balance for many home projects. The 5-1/2-inch option may suit smaller tasks, but its supplied specifications are too limited to confirm its cutting range.
Check Cutting Depth and Bevel Range
Look for the maximum cut depth at both 90° and 45° if you plan to cut thicker boards or make angled cuts. A bevel range up to 50° provides more flexibility than a saw limited to square cuts, but the depth available at an angle is usually less than at 90°. Compare the listed numbers with the material you expect to cut rather than relying on blade size alone.
Consider the Battery System and Package Contents
A cordless saw may be sold as a bare tool or as a kit with a battery and charger. The SKIL package includes a 2.0Ah battery and charger, while the DEWALT DCS590B and DCS391B are tool-only products. Battery inclusion is not clear for the BLACK+DECKER listing, and the ONEAND listing says its battery and charger are separate. Check compatibility and package contents before you buy.
Think About Runtime and Project Size
Battery capacity affects how long you can work between charges, but runtime also changes with the material, cut depth, blade condition, and pace of work. Advertised cuts or linear feet per charge are maximum claims, not promises for every job. For longer projects, consider whether you already have a spare compatible battery or can add one to your setup.
Look at Handling and Cut Control
Features such as a clear sight line, comfortable grip, solid base plate, and manageable weight can help you guide the saw. The SKIL includes a saw-line visor, the DCS391B has an overmolded grip and magnesium shoe, and the BLACK+DECKER lists an aluminum base and LED. A straightedge or compatible guide rail can also help with long cuts, though accessories may be sold separately.
Choose Motor Type and Output for the Work
Brushless motors are featured on the DCS590B and BLACK+DECKER models in this group. The DCS590B has the highest stated output and speed among the supplied specifications, which makes it the better match for demanding cuts. For occasional household projects, that extra output may not be necessary, so weigh it against the cost of adding a battery and charger if they are not already in your shop.
Prioritize Clear Product Information
Before ordering, confirm the exact model, brand, battery platform, blade size, and included accessories. This matters especially for the ONEAND listing, whose supplied brand and description do not align with its product title. If specifications are unclear, choose a model with verified details rather than guessing about compatibility or cutting capacity.
Frequently Asked Questions
Which cordless circular saw is the best choice for most DIYers?
The SKIL CR540602 is the easiest starting point in this group because it includes a 2.0Ah battery and charger, along with a 0° to 50° bevel range. If you already own compatible DEWALT batteries or need more cutting capacity, one of the DEWALT models may suit you better.
Is a 6-1/2-inch circular saw enough for home projects?
A 6-1/2-inch saw can handle many common wood-cutting tasks, but the right choice depends on material thickness and cut angle. Check the saw’s stated depth at 90° and 45° to make sure it can handle your planned cuts.
Do these saws include a battery and charger?
The SKIL package includes a 2.0Ah battery and charger. The DEWALT DCS590B is tool only, and the DCS391B is listed without a battery. The ONEAND title says its battery and charger are sold separately. The supplied BLACK+DECKER details do not clearly state whether they are included.
What does a brushless motor mean for a DIY saw?
Brushless describes the motor design. In this group, the DEWALT DCS590B and BLACK+DECKER models are identified as brushless. Compare their listed output and cutting specifications with your needs, since the motor label alone does not tell you whether a saw is the right fit for a project.
Is the DEWALT DCS590B worth choosing over the DCS391B?
The DCS590B has a brushless motor, higher listed speed, and a stated maximum cut depth of 2-9/16 inches at 90°. The DCS391B lists a 5,150 RPM motor, magnesium shoe, and 0° to 50° bevel capacity. Choose based on your required cutting capacity and the details that matter most to your work.
Can I use a circular saw to make angled cuts?
Yes, if the saw has an adjustable bevel base. The SKIL, DCS391B, and BLACK+DECKER list bevel adjustment up to 50°. Set the angle carefully and check the reduced cutting depth available when the blade is tilted.
Final Recommendation
For a first cordless circular saw, the SKIL 20V kit is the most straightforward pick because its battery and charger are included and its bevel range covers common angled cuts. If you already own compatible DEWALT batteries and want greater stated cutting capacity, consider the brushless DCS590B. The BLACK+DECKER offers useful features for compact DIY work, while the DCS391B is a reasonable battery-platform choice. The ONEAND listing needs careful verification because its supplied product details are inconsistent.
