Best 18 Volt Circular Saws for Home Projects and Jobsite Cuts
The best 18-volt circular saw depends on the cut depth, bevel range, and battery platform you need. The RYOBI ONE+ HP is best for deeper cuts and demanding work, while the Makita XSS02Z offers a 6-1/2-inch blade with a stated 2-1/4-inch cutting depth at 90 degrees. The RYOBI P505 is suited to users who value a clear blade guard, and the Milwaukee and RIDGID models offer distinct features for general cutting tasks. These are tool-only listings, so check what battery and charger you already own before choosing.
| Saw | Best For | Notable Listed Feature |
|---|---|---|
| RYOBI ONE+ HP 7-1/4-inch | Deeper cuts and demanding jobs | 2-9/16-inch depth at 0 degrees |
| Makita XSS02Z 6-1/2-inch | Cutting capacity and bevel range | 2-1/4-inch depth at 90 degrees |
| RYOBI P505 5-1/2-inch | Visibility and angled cuts | Clear lower guard; bevel to 50 degrees |
| Milwaukee 2630-20 6-1/2-inch | Durability and grip | Magnesium guards and soft-grip handle |
| RIDGID 6-1/2-inch | Blade stopping and bevel cuts | Electronic blade brake; 50-degree bevel |
RYOBI ONE+ HP 7-1/4-Inch Brushless Saw

This RYOBI is best for buyers who need the cutting capacity of a 7-1/4-inch blade. Its listed maximum depth is 2-9/16 inches at 0 degrees and 1-13/16 inches at 45 degrees, making it the deepest-cutting option among these five based on supplied specifications. The brushless motor is listed at 5,000 RPM, with bevel detents at 0, 15, 22.5, 30, 45, and 56 degrees.
Choose this saw if cut depth and quick bevel settings matter more than compact size. The listing states up to 370 cuts per charge, but actual results can vary with the battery, material, and cutting conditions. It is tool-only, so a compatible battery and charger are not included in the listed package.
Makita XSS02Z 6-1/2-Inch Saw

The Makita XSS02Z is best for buyers seeking a 6-1/2-inch saw with a stated 2-1/4-inch cutting capacity at 90 degrees. Its electronically controlled motor is listed at 3,700 RPM. A precision-machined aluminum base is intended to support smooth, accurate cuts, and the saw has a bevel range from 0 to 50 degrees.
It is a better fit than a compact 5-1/2-inch model when you need the listed cutting depth and a wide bevel range. The main limitation is that this is a tool-only listing; the battery and charger are not included. Confirm that the battery system you own matches the saw before purchase.
RYOBI P505 5-1/2-Inch Saw

The RYOBI P505 is best for buyers who prioritize visibility and grip in a smaller-blade saw. Its listed speed is 4,700 RPM, and its transparent lower guard helps keep the work area visible while cutting. The handle has a rubber overmold, and the foot adjusts for bevel cuts up to 50 degrees.
Choose this model if you want a compact-format saw with a clear guard and adjustable bevel. Its 5-1/2-inch blade is smaller than the blades on the Makita, Milwaukee, RIDGID, and RYOBI HP models, so buyers needing the greatest cutting depth should compare those options first. The listing specifies that the battery is not included.
Milwaukee 2630-20 6-1/2-Inch Saw

The Milwaukee 2630-20 is best for buyers looking for listed durability features and a comfortable grip. Its motor is specified at 3,500 RPM, and the product description cites cutting materials such as LVL headers. Magnesium upper and lower guards are included for durability and blade protection, while a soft-grip handle is intended to support controlled handling.
This is a practical option if guard construction and grip are priorities. The supplied feature information does not state the saw’s maximum cutting depth or bevel range, so compare those specifications if your projects require particular cut dimensions. It is identified as a bare tool.
RIDGID 6-1/2-Inch Cordless Saw

The RIDGID 18V saw is best for buyers who want a stated electronic blade brake and bevel capacity up to 50 degrees. Its listed no-load speed is up to 3,700 RPM. These details make it a useful comparison for general-purpose cutting when bevel adjustment and blade stopping are important purchase considerations.
Choose this model if the brake and bevel range fit your priorities. The provided product information does not specify cutting depth, so check the full product details if you need to cut material of a particular thickness. The listing is tool-only, meaning the battery and charger are not included.
Buying Guide: How to Choose an 18V Circular Saw
What blade size and cutting depth do you need?
Blade diameter is a starting point, but the listed cutting depth is more useful when checking whether a saw can handle your material. The RYOBI HP specifies 2-9/16 inches at 0 degrees, while the Makita specifies 2-1/4 inches at 90 degrees. The 5-1/2-inch RYOBI P505 is the smaller-blade option here. Compare the maker’s depth specifications with the thickness of the material you expect to cut.
Do you need bevel cuts?
For angled cuts, compare the maximum bevel angle and the adjustment stops. The Makita and RYOBI P505 list capacity up to 50 degrees; the RIDGID also lists a 50-degree bevel. The RYOBI HP provides several detents, including 45 and 56 degrees. Detents can help with repeatable angle settings, but the appropriate range depends on the cuts your projects require.
Does the battery platform matter?
These listings are tool-only or bare-tool products, so do not assume a battery or charger is included. Check the exact battery platform and the contents of the package before ordering. If you already own compatible batteries, staying within that platform may simplify tool ownership. Do not assume that batteries from different brands are interchangeable.
Which other features should you compare?
Compare listed motor speed, guard design, handle features, and blade brake availability, but do not use RPM alone to predict cutting performance. A clear lower guard is a stated feature of the P505; Milwaukee lists magnesium guards and a soft-grip handle; RIDGID lists an electronic blade brake. Match these features to your handling and project needs.
Frequently Asked Questions
What does 18V mean on a circular saw?
It identifies the saw’s stated battery voltage class. Check the exact battery platform and product package details to determine what battery is needed and whether one is included.
Which saw listed here has the greatest stated cutting depth?
The RYOBI ONE+ HP lists a maximum cutting depth of 2-9/16 inches at 0 degrees, the greatest stated depth among these five products.
Are batteries included with these saws?
The supplied listings identify these models as tool-only, bare-tool, or battery-not-included products. Verify the package contents before buying.
Is a higher RPM always better?
No. RPM is one specification, not a complete measure of cutting suitability. Blade size, cutting depth, bevel range, material, and battery platform also matter.
Which listed saw offers a 50-degree bevel?
The Makita XSS02Z, RYOBI P505, and RIDGID saw each list bevel capacity up to 50 degrees.
