How we chose the best cordless circular saws
We compared cutting capacity, battery systems and handling features to identify useful choices for different projects. The DCS391B leads for general cutting, while the other picks address compact work, full-size capacity and existing battery collections.
Blade diameter helps sort the options, but it doesn't guarantee the depth a particular saw can cut. Bevel capacity also needs context: reaching an angle does not mean a saw can cut your full material thickness at that angle.
We gave practical attention to the shoe, grip, blade brake and included equipment. Those details affect how you set up a cut and what else you need before starting.

Which cordless circular saw fits your work?
Choose the DCS391B for general projects, then consider a specialist model if your material, preferred handle layout or battery collection points elsewhere. Each option below has a clear role and a reason to pass.
DeWalt DCS391B 20V Circular Saw: Best for everyday DIY cutting
- 6-1/2 in blade
- 5,150 RPM motor
- Bevel capacity up to 50 degrees
- Magnesium shoe
A practical general-purpose choice for buyers who already have compatible DeWalt batteries. The magnesium shoe and rubber overmolded grip support routine project work.
Pros
- 50-degree bevel capacity
- Magnesium shoe
- Rubber overmolded comfort grip
Cons
- Battery and charger sold separately
The DCS391B suits a homeowner or DIY builder who wants a general-purpose saw for varied wood projects. Its 6-1/2 in blade is a sensible middle ground between a compact repair saw and a full-size framing format.
The magnesium shoe provides a base for guiding the tool, while the rubber overmolded grip gives you a defined holding surface. Its bevel adjustment reaches 50 degrees for projects that call for angled edges.
Buy it if you already have a suitable DeWalt battery and charger. Without those, compare the DCS391P1 kit before building a separate package around this bare tool.
Skip it if your regular work requires the deeper capacity of a full-size option or you specifically want a model with a documented electric brake. Our DCS391 review covers its features and buyer fit in more detail.
DeWalt DCS571B 4-1/2 Inch Circular Saw: Best for small repair projects
- 4-1/2 in blade
- Brushless motor
- Removable auxiliary handle
- Electronic blade brake
Choose this compact saw for repairs that fit its capacity: 2x material at 90 degrees and 1x material at 45 degrees. A rip fence and dust port adaptor are included.
Pros
- Removable auxiliary handle
- Onboard blade key storage
- Electronic blade brake
Cons
- 45-degree cutting capacity is limited to 1x material
- Battery and charger sold separately
The DCS571B fits small repair projects where you want a compact cutting format without giving up all lumber-cutting ability. It cuts 2x material at 90 degrees, but angled cuts at 45 degrees are limited to 1x lumber.
That distinction matters for projects with beveled framing pieces. A compact blade can complete the square cuts yet still leave you needing another saw for the angled ones.
The removable auxiliary handle, included rip fence and dust port adaptor give you useful setup options. Keep the auxiliary handle installed whenever the instructions call for it, and use the onboard blade key storage to keep the change tool nearby.
Choose this saw for work within those limits; skip it as your only saw if thicker bevel cuts are routine. Our best mini and compact circular saws guide covers other small formats.
DeWalt DCS578B FLEXVOLT Circular Saw: Best for deep framing cuts
- 7-1/4 in blade
- Maximum 2-9/16 in cut depth at 90 degrees
- Bevel capacity up to 57 degrees
- Electric brake
A full-size option for framing and thicker stock within its cutting limits. Choose it when the FLEXVOLT battery system fits your workshop.
Pros
- 57-degree bevel capacity
- Electric brake
- Integrated LED
Cons
- Requires a compatible FLEXVOLT battery
- Battery and charger sold separately
The DCS578B is a strong fit when cutting capacity matters more than keeping the saw format small. Its 2-9/16 in maximum depth at 90 degrees gives you a clear capacity figure to compare with your stock.
The bevel range reaches 57 degrees, with stops at common angles. Those stops help with repeated setups, although you should still verify the angle before cutting parts that must fit together.
An LED illuminates the cut area, an electric brake helps stop the blade after release, and a rafter hook provides convenient storage between tasks. None replaces a clear work area and secure material support.
Choose it if your work justifies a full-size FLEXVOLT saw and the required battery setup. Skip it for occasional small repairs if you'd rather stay with your current battery system.
Read our DCS578B review or DCS578B vs DCS590B comparison before choosing between the full-size DeWalt options.
Milwaukee M18 2630-20 Circular Saw: Best for M18 repair work
- 6-1/2 in circular saw
- 3,500 RPM motor
- Aircraft aluminum shoe
- Magnesium upper and lower guards
A mid-size option for existing M18 users who need a saw for repairs and general carpentry. Its aluminum shoe and soft-grip handle are useful features for guided cuts.
Pros
- Aircraft aluminum shoe
- Magnesium upper and lower guards
- Soft-grip handle
Cons
- Bare tool, with no battery or charger
The Milwaukee 2630-20 makes sense for existing M18 users who need a mid-size saw for repairs and general carpentry. Its aircraft aluminum shoe, magnesium guards and soft-grip handle are the main reasons to consider this model.
A firm shoe-to-guide contact matters during a rip cut. Keep the shoe flat on supported material rather than tilting the saw to chase the pencil line.
Its 3,500 RPM motor should not be judged against another saw by speed alone. Blade diameter, tooth design, material and feed pressure all affect how a cut progresses.
Choose it when you want this size of saw within your M18 setup. Skip it if your main requirement is a full-size brushless model with an LED and electric brake; the next Milwaukee option offers those features.
This bare tool needs a compatible battery and charger.
DeWalt DCS590B 20V XR Circular Saw: Best for 20V workshop upgrades
- 7-1/4 in brushless saw
- Maximum cut depth of 2-9/16 in at 90 degrees
- Maximum cut depth of 2 in at 45 degrees
- Electric brake
A full-size upgrade for DeWalt 20V MAX users who need more cutting capacity. Its right-side blade and top handle offer a different layout from the rear-handle DCS577B.
Pros
- Brushless motor
- Electric brake
- 57-degree bevel capacity
Cons
- Battery and charger sold separately
The DCS590B is the full-size option to consider when you want to stay with DeWalt 20V MAX. It combines a brushless motor with a right-side blade and top handle.
Its maximum depth is 2-9/16 in for square cuts and 2 in at 45 degrees. That second figure is especially useful if your projects include beveled lumber rather than mostly straight crosscuts.
An electric brake and bevel stops at 22.5 and 45 degrees support repeated project work. Before choosing it, think about how the right-side blade fits your stance and view of the cut line.
Buy it if you need the cutting capacity and already have a suitable battery setup. Skip it if you prefer a rear handle and left-side blade, or if a smaller saw covers everything you cut.
Battery and charger are sold separately.
Milwaukee M18 7-1/4 Inch Circular Saw: Best for M18 framing work
- 7-1/4 in saw
- Brushless motor
- Electric brake
- Integrated LED light
A full-size M18 choice with an LED, brake and dust port for a regular cutting setup. Confirm its depth capacity at the angles your work requires.
Pros
- Integrated LED light
- Electric brake
- Magnesium upper and lower guards
Cons
- Bare tool, with no battery or charger
The Milwaukee 2631-20 suits M18 users who want a full-size brushless saw with useful work-area features. Its LED, electric brake and integrated dust port distinguish it from the smaller 2630-20 in this roundup.
A light helps you see the line, but check for shadows before committing to a long cut. The dust port gives you a connection point for compatible extraction equipment; it does not remove the need for suitable dust protection.
Magnesium upper and lower guards and a rafter hook round out its feature set. Use the hook only where the tool can hang securely without creating a falling hazard.
Choose it for an M18 workshop that needs a 7-1/4 in format. Skip it if a smaller saw meets your needs, and confirm its depth capacity in the manual before planning thick or beveled cuts.
Makita XSH03Z 6-1/2 Inch Circular Saw: Best for Makita LXT users
- 6-1/2 in blade
- Brushless motor
- Automatic Speed Change technology
- 5,000 RPM motor
A mid-size saw for compatible LXT battery owners who want automatic speed and torque adjustment. The package includes a blade but no battery or charger.
Pros
- Brushless motor
- Adjusts speed and torque during cuts
- Star protection monitors tool and battery conditions
Cons
- Battery and charger sold separately
The Makita XSH03Z is the natural starting point for compatible 18V LXT battery owners who want a mid-size brushless saw. Automatic Speed Change adjusts speed and torque as cutting demands change.
That feature doesn't change good feed technique. Keep steady forward pressure and let the blade cut, rather than leaning harder on the tool when resistance increases.
Makita's Star protection system monitors conditions between compatible tools and batteries to help protect against overload, overheating and over-discharge. Check the required battery compatibility, including the Star symbol, before buying.
Choose this saw if it fits your LXT setup and you don't need a larger format. Skip it if your planned cuts require capacity beyond what the manual allows.
A blade is included, but you'll need a battery and charger; don't assume every Makita battery family fits.
Ryobi ONE+ P505 5-1/2 Inch Circular Saw: Best for Ryobi household projects
- 5-1/2 in blade
- Bevel adjustment up to 50 degrees
- Extra side handle
- Clear lower guard
A household-project option for buyers with compatible Ryobi batteries. The clear lower guard and extra side handle help you see and control the cut.
Pros
- Bevels up to 50 degrees
- Extra side handle
- Clear lower guard
Cons
- Battery not included
- Check depth capacity before choosing it for thicker stock
The Ryobi P505 is a practical choice for household projects within a ONE+ setup. Its 5-1/2 in blade format suits buyers who want a smaller saw for work around the house.
The clear lower guard helps you view the work, while the extra side handle provides a second grip position. Keep both hands in the approved positions rather than moving one near the blade to improve your view.
Its bevel adjustment reaches 50 degrees, but check the actual depth available at your chosen angle. A wide angle range doesn't tell you whether a particular board can be cut through.
Choose it if you already have compatible Ryobi batteries and your project thickness fits. Skip it if deeper cuts are the main reason you're buying a saw, since capacity should settle that choice before convenience features.
DeWalt DCS577B FLEXVOLT Framing Saw: Best for rear-handle framing
- 7-1/4 in framing saw
- Blade left of motor
- 53-degree bevel capacity
- Magnesium shoe
Choose this framing saw for its rear handle and left-side blade. An integrated blower helps keep the cut line clear.
Pros
- Rear-handle layout
- Integrated dust blower
- Electronic brake
Cons
- Battery sold separately
- Rear-handle format may not suit occasional small repairs
The DCS577B is for buyers who specifically prefer rear-handle framing saws. Its blade sits left of the motor, giving it a different sightline and holding position from the top-handle DCS590B.
The maximum square-cut depth is 2-7/16 in, and the bevel range reaches 53 degrees. An integrated blower helps clear the cut line, while the magnesium shoe provides the guiding surface.
Choose this model because the layout fits your cutting stance and framing work. A rear handle doesn't automatically make a saw the right choice for every user or every workspace.
Skip it for occasional small repairs if you'd find a shorter general-purpose format easier to manage. It also requires the FLEXVOLT battery setup.

DeWalt DCS391P1 6-1/2 Inch Circular Saw Kit: Best for first-time cordless buyers
- 6-1/2 in blade
- 5,150 RPM motor
- 50-degree bevel capacity
- Includes 5.0 Ah battery and charger
The DCS391 format in a package for buyers starting without compatible batteries. It includes a battery, fast charger, blade and kit box.
Pros
- Battery and charger included
- Magnesium shoe
- Cuts 2x material at 90 and 45 degrees
Cons
- Includes a battery and charger you may already own
The DCS391P1 is the sensible DCS391 package for starting without compatible batteries. It includes a 5.0 Ah battery, fast charger, blade and kit box.
Its core saw specifications match the DCS391B, so choose between the packages by what you need in the box. The kit's lower position here doesn't mean you should buy the bare tool and then discover you still need a power source.
This model cuts 2x material at both 90 and 45 degrees, making the package useful for mixed square and angled lumber cuts. Check that those capabilities cover your planned projects before settling on it.
Choose the kit for a first cordless saw setup. Skip it if you already have enough suitable batteries and a charger, unless you specifically want another pack for project rotation.
What should you compare before buying a cordless circular saw?
Compare required cut depth, battery fit and handling first. Motor speed and extra features become useful tie-breakers after those needs are met.
Which blade size makes the best cordless circular saw for you?
Choose the smallest format that comfortably covers your regular cuts. Measure actual stock thickness, then check the saw's capacity at both square and bevel settings.
Nominal lumber names describe a size category rather than the board's exact dimensions. Don't choose by the name alone, and don't assume two saws with the same blade diameter have identical capacity.
A guide placed under the shoe can also reduce usable cutting depth. Account for its thickness before planning a cut close to the saw's limit.
Does the battery platform matter more than voltage?
Compatibility comes first, because a battery with a similar voltage label may still be unsuitable. Confirm the exact battery family and the saw manual's recommendations.
Think about your whole project: if a drill, saw and work light share one battery, moving it between tools can interrupt the work. A suitable spare may be more useful than a feature you'll rarely use.
Amp-hours describe battery capacity within a compatible system, not a guaranteed number of cuts. Material, blade condition, depth and feed pressure all affect runtime.
How much do balance and blade position matter?
A saw should let you see the cut line while keeping a stable stance and approved grip. Left-side and right-side blades change the view, but neither layout is automatically correct for every right-handed or left-handed user.
Consider the saw with a battery fitted. A pack changes the balance, so bare-tool weight alone won't tell you how the working setup will feel.
Are electric brakes worth prioritizing?
An electric brake is useful for reducing blade coast after trigger release. It deserves attention if you regularly stop between short cuts.
Still wait for the blade to stop before moving or setting down the saw. A brake doesn't prevent kickback, and the lower guard must work freely.
How should you set up a cordless circular saw for clean cuts?
Start with a suitable blade, firm support and locked adjustments. A sound setup helps more than trying to correct the saw halfway through a cut.
Fit the blade to the job
Use the diameter, arbor size and blade type required by the manual. A wood-framing blade and a fine-finish blade serve different goals, and tooth count alone doesn't guarantee suitability for every material.
Remove the battery before changing blades or making adjustments. Our circular saw blade change guide explains the process alongside the tool's instructions.
Support the material without trapping the blade
Clamp the work so it can't slide or rock, and arrange support so the kerf won't close on the blade. Keep the saw's shoe supported as the cut ends.
For sheet goods, suitable sacrificial support can keep the panel stable across its area. Check underneath for clamps, fasteners and anything else the blade could strike.
Set blade depth as the manual directs, commonly with only a small amount of tooth projecting beneath the stock. Recheck the depth after changing the bevel angle.
Check the guide offset before cutting the workpiece
Measure the distance from the blade's cutting edge to the shoe edge that will follow the guide. Place the guide so the blade removes material on the waste side of the mark.
Use a scrap offcut to verify the setup before cutting a finished part. Our DIY track saw guide explains guide arrangements, while the circular saw guide and rail roundup helps compare options.
Which cordless circular saw mistakes should you avoid?
Avoid forcing the cut, twisting the blade and cutting unsupported stock. These habits can spoil the work and increase the chance of binding or kickback.
- Starting with the blade touching the board: let it reach operating speed before entering the material, following the manual.
- Steering sharply back toward the line: stop safely and reset the cut rather than twisting the blade in the kerf.
- Pushing through a stall: release the trigger and wait for the blade to stop before finding the cause.
- Treating a bevel stop as exact: check the angle on scrap when joint fit matters.
- Reaching under the work: keep hands clear of the blade path and secure the piece with clamps.
- Relying on a clear guard or LED for protection: wear suitable eye, hearing and dust protection.
Keep your body positioned as the manual directs, away from the likely kickback path. Our guide to using a circular saw covers the basic cutting sequence.
How do you care for a cordless circular saw?
Keep the blade, shoe, guard and vents clean, with the battery removed during maintenance. Built-up debris can hide damage and interfere with moving parts.
Check that the lower guard moves freely and returns properly before use. Stop using the saw if the guard sticks, the shoe is bent or an adjustment won't lock.
A dull or dirty blade can demand more effort and leave rougher cuts. Clean it with an appropriate method or replace it when worn or damaged, following the blade maker's guidance.
Let an overheated tool or battery cool as directed instead of repeatedly restarting it. Store batteries away from moisture and extreme temperatures, and use the charger specified for the system.
Which cordless circular saw should you choose?
Your best cordless circular saw is the one that completes your regular cuts with a suitable battery setup. Choose by the job you'll repeat, rather than the most demanding cut you might someday attempt.
Pick the DCS391B for general DIY work with compatible batteries, or the DCS391P1 kit when you're starting fresh. Choose the DCS571B for small repairs that fit its square-cut and bevel limits.
For full-size DeWalt work, choose the DCS590B to stay with 20V MAX or the DCS578B when FLEXVOLT fits your setup. Pick the DCS577B when its rear handle and left-side blade are your preferred framing layout.
Existing M18, LXT and ONE+ users should start with the matching options here, then verify cutting capacity before changing systems. If charging and battery sharing don't suit your workspace, compare the best corded circular saws.

Frequently asked questions
What size cordless circular saw should I get?
A 6-1/2 in saw is a practical starting point for general DIY work, but required cut depth should decide the size. Measure your thickest material and check capacity at the angle you need.
Choose a smaller saw for suitable repair work or a larger model when deeper cuts are part of the job.
Are cordless circular saws powerful enough for framing?
Yes, a cordless circular saw can handle framing when its capacity, blade and battery setup match the work. The DCS578B and DCS590B are full-size options in this roundup.
For repeated cuts, plan charging breaks or spare compatible batteries, support the lumber properly and avoid forcing the saw through the cut.
Should I choose a bare tool or a kit?
Choose a bare tool if you already have a suitable compatible battery and charger; choose a kit if you need both. The DCS391P1 includes those essentials.
Compare the whole setup before buying, including the battery size recommended for the saw and whether your other tools need that same battery during a project.
Is a 4-1/2 in circular saw enough for DIY projects?
Yes, if the project's stock thickness and cut angles fit the saw's capacity. The DCS571B can cut 2x lumber square, but its 45-degree capacity is limited to 1x material.
That makes it useful for suitable repairs, while thicker bevel cuts call for a different saw.
Does a larger battery make a cordless circular saw more powerful?
A larger compatible battery can provide more stored energy, but size alone does not guarantee cutting power. Battery design, the saw's requirements, blade condition and material all matter.
Follow the tool manual's battery guidance and consider how the fitted pack affects balance, especially during long cuts.
