The DEWALT DCS391B is a 20V MAX cordless circular saw designed for professionals and serious DIYers who demand portability without compromising cutting power. Its 6-1/2 inch blade and 5150 RPM motor make it a capable tool for framing, roofing, and breaking down sheet goods.
In real-world use, the saw impresses with its smooth, powerful motor that handles pressure-treated lumber and plywood with ease. The lightweight magnesium shoe keeps the saw stable and accurate, while the 0-50 degree bevel capacity allows for versatile cutting angles. Users report that with a quality 5Ah battery, the saw performs like a corded model, offering ample runtime for most jobs.
Design and build quality are typical DEWALT: robust construction with a comfortable rubber over-molded grip. The keyless blade change system is a time-saver, and the spindle lock adds safety. However, the saw's weight of about 7 pounds with a battery makes it easy to maneuver for extended periods.
Potential drawbacks include the line of sight being partially blocked by the motor and blade guard, which can make following a cut line tricky. The depth adjustment lever may also be stiff at first. Additionally, the battery and charger are sold separately, so factor that into your purchase.
Overall, the DEWALT DCS391B is a stellar cordless saw that delivers professional-grade cuts in a portable package. It's a worthy investment for anyone already invested in the DEWALT 20V MAX system or looking for a reliable, lightweight circular saw.

The BLACK+DECKER 20V 5-1/2 Inch Cordless Circular Saw (model BDCCS20B) is a bare tool designed for DIY enthusiasts who already own BLACK+DECKER's POWERCONNECT batteries. This saw is ideal for light to medium cutting tasks such as trimming plywood, cutting shelving, or making quick crosscuts on lumber. Its compact size makes it a great choice for homeowners and hobbyists who need a portable saw for small projects.
One standout feature is the tool-free depth of cut and bevel adjustment, which allows you to change settings quickly without searching for extra tools. The blade can be swapped out just as easily, reducing downtime. The pivoting shoe provides additional control, especially when cutting at angles, and the bevel detents at 45 and 90 degrees help ensure accurate angled cuts. The high torque motor delivers enough power for most DIY materials, though it is not intended for heavy-duty construction.
Build quality is typical of BLACK+DECKER's consumer-grade tools: durable enough for occasional use but not designed for daily professional abuse. The saw weighs about 6 pounds, which makes it easy to handle for extended periods. The orange and black color scheme is functional, and the overall design prioritizes simplicity and ease of use. However, the 5-1/2 inch blade means the maximum cutting depth is limited, so you won't be able to cut through thick beams or dense hardwoods.
A key drawback is that this is a bare tool, meaning you must purchase a battery and charger separately if you do not already own them. Additionally, the saw does not come with a carrying case, which may be inconvenient for some users. The lack of reviews makes it hard to gauge long-term reliability, but based on the feature set, it is a solid entry-level saw for occasional DIY tasks.
Overall, the BLACK+DECKER BDCCS20B is a practical choice for DIYers who value convenience and portability over raw power. If you already have POWERCONNECT batteries, this saw is a cost-effective addition to your tool kit. For heavy-duty or professional use, consider a larger saw with more cutting depth and a higher capacity battery system.

Pros
- Exceptional power-to-weight ratio makes it easy to handle all day
- Electric brake adds a critical safety layer and saves time between cuts
- Deep 57 degree bevel capacity expands cutting possibilities for complex joinery
- Ball bearing lower guard withstands harsh job site conditions without jamming

The DEWALT DWE575SB is a 7-1/4 inch corded circular saw engineered for professionals who demand both power and portability. Weighing just 8.8 pounds, it is among the lightest saws in its class, making it ideal for framers, roofers, and serious DIYers who need to make hundreds of cuts without fatigue.
At the heart of this saw is a 15 amp motor that delivers ample torque for ripping through pressure-treated lumber, plywood, and even hardwood. The electric brake stops the blade almost instantly after releasing the trigger, adding a critical safety layer and allowing you to move quickly between cuts. The 57 degree bevel capacity with positive stops at 45 and 22.5 degrees gives you the flexibility to tackle crown molding, rafters, and other angled cuts with precision.
Build quality is typical DEWALT: a durable aluminum smooth base ensures accurate cuts, while the ball bearing lower guard promises long life even in dusty environments. The integrated dust blower effectively clears sawdust from your cut line, maintaining visibility without needing to stop and blow. The patented Tough Cord protection system reinforces the cord entry point, reducing the risk of pull-out damage on the job site.
One potential drawback is the corded nature of the tool, which tethers you to an outlet. For those working in remote locations or on ladders, a cordless saw might be more convenient. Additionally, the absence of an LED light means you will need extra lighting in dim areas. The bevel stops are preset, so if you need a custom angle between the detents, you will have to adjust manually.
Overall, the DEWALT DWE575SB is a superb choice for anyone who values power, weight savings, and safety. Its combination of a robust motor, instant brake, and generous bevel range makes it a top contender for professional-grade cutting tasks. If you can live with a cord, this saw delivers outstanding value and performance.
Buying Guide: What to Look for in a Cyber Monday Circular Saw
Power Source: Cordless vs. Corded
Your first decision is whether you need the untethered freedom of a cordless saw or the consistent torque of a corded model. Cordless saws, like the DEWALT 20V MAX and the BLACK+DECKER 20V, let you work anywhere without dragging an extension cord. They are ideal for jobsites or outdoor projects. Corded saws, such as the DEWALT 7-1/4 inch, offer unlimited runtime and higher RPM for dense materials. Think about your typical cutting volume and access to outlets.
Blade Size and Cut Depth
Blade diameter determines what you can cut in one pass. A 5-1/2 inch blade handles most DIY tasks, while a 6-1/2 inch or 7-1/4 inch blade cuts through 2x lumber at 90 degrees and 45 degrees. The DEWALT 20V MAX offers a 2-1/8 inch depth at 90 degrees, enough for two-by material. The DEWALT corded saw goes deeper at 2-9/16 inch. Match blade size to your common materials.
Bevel Capacity and Adjustability
Bevel cuts are essential for trim work, roofing, and angled joints. Look for a saw that offers at least 45 degrees of bevel, with positive stops at common angles. The DEWALT corded model goes up to 57 degrees, giving you extra flexibility for compound cuts. The BLACK+DECKER saw has detents at 45 and 90 degrees for quick adjustments. Tool-free bevel and depth settings save time on the job.
Build Quality and Comfort
A circular saw is an investment in your productivity. Look for a magnesium or aluminum shoe for durability and accuracy. The DEWALT 20V MAX features a lightweight magnesium shoe that resists warping. Comfort grips and balanced weight reduce fatigue during extended use. The DEWALT corded saw is among the lightest in its class at 8.8 pounds. Consider the warranty and reputation of the brand.

Final Thoughts
This Cyber Monday, the best circular saw for you depends on your power preference and project scale. If you value portability and a compact design for quick cuts around the house, the BLACK+DECKER 20V 5-1/2″ Cordless Circular Saw offers an excellent balance of features and ease of use. For those tackling heavier framing or demanding cuts with maximum power, the DEWALT Circular Saw, 7-1/4 inch delivers corded reliability and deep bevel capacity. Both saws represent fantastic value during the Cyber Monday sales, and we are confident either will serve you well for years to come.
