Skil PWR CORE 20 Brushless 6-1/2 In. Circular Saw Kit Review

4.3 out of 5

The Skil Brushless 6-1/2 In. Circular Saw Kit, model CR6413B-11, caught my eye due to its impressive feature set and the promise of improved performance thanks to its brushless motor. After spending some time with this tool, I have a comprehensive understanding of its strengths and weaknesses.

First Impressions

Upon unboxing, the Skil circular saw immediately felt solid and well-constructed. At 5.3 pounds, it is relatively lightweight, which is a significant advantage when working on prolonged projects. The ergonomic design, with the blade positioned on the left, provides excellent visibility of the cut line. This feature stood out to me as it made it easier to track and control cuts, especially when working on intricate projects.

Performance

The brushless motor, which operates at up to 5,500 RPM, is a powerhouse. I was able to make quick, clean cuts through 2x4 pine without any noticeable strain on the motor. The saw's ability to make 105 cuts on a single charge with the included PWRCORE 20™ 2.0Ah lithium battery is impressive. This extended runtime is a game-changer for those who need to work continuously without frequent interruptions to recharge.

However, I did encounter some hiccups. On a few occasions, the saw stalled unexpectedly. This was particularly noticeable when cutting through thicker materials. While it did resolve itself after a few moments, it was a bit concerning when considering the tool's reliability for more demanding tasks.

Usability

One of the standout features of this saw is its ease of use. The ergonomic handle and lightweight design reduce fatigue, making it comfortable to use over extended periods. The LED light is another thoughtful addition, significantly enhancing visibility in low-light conditions and ensuring precision.

The electric brake is a crucial safety feature, stopping the blade quickly once the trigger is released. This not only prevents accidents but also makes transitioning between cuts faster and safer.

Cutting Capacity and Versatility

With a 6-1/2 inch blade, the saw offers a sawing capacity of 2-1/4 inches at 90° and 1-5/8 inches at 45°. The bevel capacity ranges from 0 to 45°, allowing for a variety of angled cuts. These specifications make it versatile enough for most DIY projects and some professional applications.

However, I did notice that the saw struggled a bit with materials over 1/4 inch thick. It seemed more suited for trimming and lighter cutting tasks rather than heavy-duty ripping. This limitation might be a dealbreaker for those looking to tackle more substantial construction projects.

Battery Life and Charging

The advanced battery technology in the Skil circular saw promises longer runtime and battery life. In my experience, the battery did hold up well, providing consistent power throughout my projects. The included 20V standard charger is efficient, bringing the battery back to full charge relatively quickly.

Durability

Durability is always a concern with power tools, and the Skil circular saw is no exception. While the tool feels robust and well-made, the occasional stalling issue raises questions about its long-term reliability. For light to moderate use, I believe it will hold up well, but for more intensive applications, it might not be the most dependable choice.

Final Thoughts

The Skil Brushless 6-1/2 In. Circular Saw Kit offers a lot of value, especially for the price point. Its brushless motor, ergonomic design, and added features like the LED light and electric brake make it a strong contender in the circular saw market. The tool is particularly well-suited for DIY enthusiasts and those working on light to moderate projects.

However, the occasional stalling issue and its struggle with thicker materials are notable drawbacks. If you need a saw for heavy-duty tasks, you might want to consider other options.

Recommendation

Would I recommend the Skil Brushless 6-1/2 In. Circular Saw Kit? For DIYers and those needing a reliable tool for light to moderate tasks, absolutely. Its ease of use, extended battery life, and safety features make it a great addition to any toolkit. However, for professionals or those tackling more demanding projects, the stalling issue and limited cutting capacity might be a concern. In such cases, investing in a higher-end model might be worth the extra cost.


Project Ideas

Business

Mobile Trim & Shelf Install Service

Offer on-site cutting/installation of baseboards, door casing, closet shelves, and floating shelves. The cordless 6-1/2 in. saw, blade-left visibility, and LED line enable precise scribe cuts in apartments or offices; the vacuum adaptor keeps dust controlled. Bill per room/linear foot.


Custom Vendor Display Kits

Build and sell flat-pack market displays—stackable crates, risers, sign stands—tailored to craft fair vendors and boutiques. Batch parts with repeatable cuts; promote lightweight, tool-free assembly. Upsell branding with stencils or laser-burned logos.


Reclaimed Wood Decor Microbrand

Source pallets/fence boards and produce geometric wall art, coat racks, hex shelves, and narrow benches. The thin-kerf blade and electric brake speed batch work; one battery nets ~100+ 2x4 cuts for a day’s prep. Sell via Etsy and local pop-ups with made-to-size options.


On-Demand Cutting & Door-Trim Service

Provide accurate on-site cuts for doors, butcherblock, and shelving using a straightedge guide. The saw’s left-side blade and LED make finish-side-up cuts predictable; pair with painter’s tape and a fine-tooth blade for clean edges. Charge per cut plus travel.


Hands-On Workshops

Host weekend classes (French cleat walls, planter boxes, wall art). Teach circular-saw safety, straightedge use, and bevel techniques; students leave with a finished project. Partner with community centers and include materials in the fee.

Creative

French Cleat Storage Wall Kit

Batch-cut 45° beveled cleats and matching wall strips from 3/4 in. plywood to create a modular shop or pantry organizer. The blade-left design and LED shadow line make the bevel orientation and layout easy, and the 2-1/4 in. depth covers standard sheet rip strips when used with a straightedge. Include a few cleat-backed bins and tool holders in the kit.


Mid-Century Plant Stand Trio

Make a set of three stands with splayed legs (10–15°) from 1x2/2x2 stock and round or square tops. Use the 0–45° bevel capacity for crisp angles and the electric brake for safe, frequent test fits. Finish with contrasting stains to sell as a minimalist set.


Stackable Market Crates

Cut 1x8 sides and 1x3 slats into uniform lengths for interlocking crates that double as display risers. Use repeated shallow passes to form simple half-lap corners, and the vacuum adaptor to keep dust down when cutting indoors. Add handhold cutouts and stencil graphics.


Geometric Reclaimed-Wood Wall Art

Create starburst or chevron panels by crosscutting pallet/reclaimed boards at 22.5° and 45°. The LED shadow-line helps align tight miters, and the thin-kerf blade reduces tear-out on brittle, weathered wood. Mount pieces on a plywood backer and frame them.


Floating Box Shelves

Cut 45° miters on 1x8 or plywood strips to form seamless box shelves with hidden cleat mounts. The brushless motor’s smooth startup and electric brake help during delicate glue-ups and test fits. Finish with edge banding for a furniture-grade look.
