5 Top Brushless Circular Saws

These ranked picks count down to the top choice, with each brushless saw matched to different cutting needs and budgets.

5. CRAFTSMAN V20 RP Cordless Circular Saw (CMCS551B)

Best for: DIY framing and sheet-good cuts

The CRAFTSMAN V20 RP CMCS551B is a cordless circular saw with a 7-1/4-inch blade. It is sold as a bare tool, so the package does not include a battery or charger. That matters if you do not already own CRAFTSMAN V20 packs. Around $149, it fits a midrange price point before adding those parts.

A brushless motor is rated for up to 75% more power than the brand’s comparison point, though actual cutting performance depends on the battery, blade, and material. An LED lights the cut line and nearby work surface, which helps in dim garages or on shadowed boards. The saw tilts to a 56-degree bevel, with positive stops at 22.5 and 45 degrees for common angled cuts. Its upper metal guard should take more abuse than a plastic guard, but the tool still needs careful handling and a suitable blade for each job.

Pros

• The 7-1/4-inch blade suits common framing lumber and sheet goods.
• The 56-degree bevel range supports angled cuts beyond standard 45-degree work.
• The LED improves visibility along the cut line in low light.

Cons

• Bare-tool packaging requires a separate V20 battery and charger.
• Battery runtime and cutting strength vary with pack size and material.

3. Makita XSH03Z Brushless Cordless Circular Saw

Best for: Framing and sheet-goods cuts

Makita XSH03Z is a cordless 6-1/2-inch circular saw for Makita 18V LXT battery users. It is sold as a tool only, so the package does not include a battery or charger. Around $210, it targets buyers who already own compatible packs and want a compact saw for framing, plywood, and general jobsite work. Its 6-1/2-inch blade size handles common sheet materials, though users should match blade choice and cutting depth to the material.

The brushless motor reaches 5,000 RPM and electronically adjusts power as cutting resistance changes. Makita calls this Automatic Speed Change technology. In practical terms, the saw can alter speed and torque during a cut instead of holding one fixed output. The motor also avoids carbon brushes, which removes one wear item and helps it run cooler. Makita rates the motor system for up to 50% longer runtime per charge than comparable brushed setups, although actual runtime depends on battery size, material, blade, and cutting load. The cordless design removes the power cord, but a battery adds weight and cost.

Pros

• 5,000 RPM supports quick crosscuts and ripping.
• Brushless motor reduces brush replacement needs.
• Automatic adjustment matches torque and speed to load.

Cons

• Battery and charger are not included.
• A 6-1/2-inch blade offers less depth than 7-1/4-inch saws.

2. RYOBI ONE+ HP 18V Circular Saw

Best for: DIY framing and renovation cuts

This tool-only circular saw runs on RYOBI ONE+ 18V batteries, so existing battery owners can add it without buying a new platform. Its brushless motor spins the 7-1/4-inch blade at 5,000 RPM. RYOBI rates it for up to 370 cuts per charge, though the result depends on the battery size, wood, and cutting depth. The saw reaches 2-9/16 inches at 0 degrees and 1-13/16 inches at 45 degrees, covering common lumber and sheet-good work.

Angle cuts are easy to set with detents at 0, 15, 22-1/2, 30, 45, and 56 degrees. A built-in LED helps light the cut line, while the integrated pommel handle gives the front hand another grip. The die-cast upper guard should handle regular jobsite contact better than a lightweight plastic guard. A dust-port adapter fits 1-1/4- to 1-7/8-inch hoses, and the rafter hook supports quick storage. Around $130, it costs more than basic corded saws, and the package does not include a battery or charger.

Pros

• 2-9/16-inch depth handles many 2-by framing cuts in one pass.
• Six bevel detents make repeatable angled cuts quicker.
• LED, front handle, and dust-port adapter improve control and cleanup.

Cons

• Tool-only pricing means ONE+ newcomers need a battery and charger.
• Battery runtime and the claimed 370-cut capacity vary with material and battery size.

1. DEWALT DCS590B 20V MAX XR Cordless Circular Saw

Best for: Frequent framing and renovation cuts

The DEWALT DCS590B is a cordless circular saw built around a 7-1/4-inch blade and DEWALT’s 20V MAX battery platform. Its brushless motor reaches up to 5,500 RPM at no load and produces up to 1,700 MWO for demanding cuts. This is a tool-only package, so the battery and charger are not included. At around $181, it makes the most sense for shoppers who already own compatible DEWALT batteries.

Its cutting capacity fits common framing and remodeling work. The saw reaches 2-9/16 inches at 90 degrees and 2 inches at 45 degrees, enough for many dimensional lumber cuts in one pass. DEWALT rates it for up to 368 cuts per charge, but the actual count depends on the material, blade, battery size, and cut depth. An electric brake stops the blade after trigger release, which helps reduce coasting before repositioning the saw. Buyers starting from scratch should also budget for a battery and charger.

Pros

• The 7-1/4-inch blade cuts up to 2-9/16 inches deep at 90 degrees.
• The brushless motor delivers up to 5,500 RPM and 1,700 MWO.
• The electric brake stops the blade after releasing the trigger.

Cons

• The tool-only package requires a separate 20V MAX battery and charger.
• The advertised 368 cuts per charge is a maximum rating, not a guaranteed result.

Buying Guide

Battery platform compatibility is the most important factor when choosing a cordless circular saw. A saw that shares batteries with your drill or impact driver can save $60 to $150 on duplicate battery packs.

• Blade size: Choose a 7 1/4-inch model for common framing lumber and sheet goods. A 6 1/2-inch saw weighs less but may cut only about 2 1/8 inches deep at 90 degrees.
• Battery capacity: For repeated cuts, favor a 5.0Ah or larger battery. A 2.0Ah pack reduces weight, but may require more frequent charging during long projects.
• Cutting power: Look for at least 4,000 RPM and a motor rated for 2-inch lumber. Higher speed helps with clean crosscuts, while torque matters more in thick or wet wood.
• Adjustment range: Confirm a 0-to-56-degree bevel range and tool-free depth control. A positive 45-degree stop makes angled cuts faster and more consistent.
• Included equipment and cost: Compare bare-tool prices near $100 to $180 with kits around $180 to $350. Check for a blade, charger, battery, rafter hook, and carrying case.

If you cannot have everything, prioritize battery compatibility, then choose the largest capacity pack your budget supports.

Frequently Asked Questions

How does a brushless circular saw compare with a brushed model?

A brushless circular saw runs cooler, wastes less battery power, and usually needs less maintenance than a brushed version. Its electronic motor control can extend runtime, but the tool often costs more upfront. For example, a 20-volt model may cut more boards per charge than a similar brushed saw, depending on battery size and material.

What size blade do most cordless circular saws use?

The right blade size for most full-size cordless circular saws is 7-1/4 inches, while compact models commonly use 6-1/2-inch blades. A 7-1/4-inch saw can usually cut about 2-1/2 inches deep at 90 degrees. Check the manual before buying blades, since arbor sizes and maximum depths vary.

Can a cordless brushless circular saw cut pressure-treated lumber?

Yes, a cordless brushless circular saw can cut pressure-treated lumber when it has enough power, a sharp blade, and a suitable cutting depth. Use a carbide blade with at least 24 teeth for fast framing cuts, and support long boards to limit binding. A 5.0Ah battery often provides more useful runtime than a smaller pack.

Are brushless circular saws worth the higher price?

Brushless circular saws are worth the higher price for frequent cutting, overhead work, or jobs far from outlets, but occasional users may save money with a brushed or corded model. A cordless brushless kit can cost $150 to $350 before extra batteries, so include charger and battery costs in the comparison.

Conclusion

The DEWALT DCS590B 20V MAX XR Cordless Circular Saw is the strongest fit for homeowners, remodelers, and tradespeople who want cordless power for regular framing and sheet-good cuts. If lower weight matters more than maximum cutting capacity, pick a compact 18V or 20V saw instead, since it should feel easier to control during overhead work and longer sessions. Before buying, double-check the blade size, battery compatibility, included accessories, package quantity, and current price. A bare-tool package may cost less, but it does not include a battery or charger. Also confirm that your existing battery platform matches the saw. That single check can prevent an unexpected extra purchase.
