A cordless circular saw should match the material, blade capacity and battery system you actually use. We compared current manufacturer documentation for three exact 6-1/2-inch models. HandyTested has not cut lumber or measured runtime, brake time, accuracy, dust collection or ergonomics with these saws.
Quick comparison
| Exact model | Motor and no-load speed | Package | Best fit on paper |
|---|---|---|---|
| DEWALT DCS565B | Brushless; 4,950 RPM | Bare tool with blade; battery and charger excluded | Existing DEWALT 20V MAX users who want a 50-degree bevel |
| SKIL CR6413B-11 | Brushless; 5,500 RPM | 2.0Ah battery and charger kit | A complete starter package |
| Makita XSS02Z | Brushed; 3,700 RPM | Bare tool with blade; battery and charger excluded | Existing Makita 18V LXT users |
Prices move and package contents differ, so this guide does not promise a fixed ceiling. A bare tool can be economical when you already own compatible batteries, while a kit may cost less than assembling a new platform separately.
DEWALT DCS565B: compact 20V MAX bare tool
DEWALT lists DCS565B as a brushless 6-1/2-inch saw with 4,950 no-load RPM, a 0-50-degree bevel range, electric brake, LED and rafter hook. The listing includes a blade, blade wrench and dust chute, but the battery and charger are sold separately.
Trade-off: it makes the most sense for someone already invested in DEWALT 20V MAX or FLEXVOLT batteries. The manufacturer page does not turn no-load speed into a universal cutting-performance ranking.

SKIL CR6413B-11: brushless starter kit
SKIL documents a brushless 6-1/2-inch saw with 5,500 no-load RPM, 2-1/4-inch cutting capacity at 90 degrees and 1-5/8 inch at 45 degrees. The bevel range is 0-45 degrees. Configuration CR6413B-11 includes a 2.0Ah PWR CORE 20 battery, charger, 18-tooth blade, hex key and vacuum adaptor.
Trade-off: the included 2.0Ah battery makes this the clearest complete package here, but runtime varies with blade, material, depth, feed rate and battery condition. The maker’s cut-count claim is a specific test scenario, not a promise for every project.

Makita XSS02Z: documented 18V LXT bare tool
Makita lists XSS02Z with a brushed motor at 3,700 no-load RPM, 2-1/4-inch capacity at 90 degrees, 1-9/16 inch at 45 degrees and a 0-50-degree bevel range. A 16-tooth blade is included; the 18V LXT battery and charger are not.
Trade-off: its brushed motor and lower published no-load speed distinguish it from the two brushless choices. That does not by itself predict cut quality: blade selection, sharpness, material and technique remain decisive.

How to choose
- Start with the battery platform: confirm exact battery compatibility and whether a charger is included.
- Check the required cut: blade diameter alone is not enough; compare depth at 90 and 45 degrees with the stock you plan to cut.
- Choose the correct blade: match diameter, arbor, tooth pattern, maximum speed and material to the saw manual.
- Look beyond RPM: no-load speed cannot establish power, runtime, cut finish or resistance to stalling across different saws.
- Plan dust control: an adaptor still requires a compatible extractor and does not replace respiratory or eye protection.
Safe setup before every cut
- Remove the battery before changing the blade or adjusting the shoe, bevel or depth.
- Confirm the lower guard closes freely and the blade is correct, sharp, undamaged and securely installed.
- Support the work on both sides of the cut without trapping the kerf, and keep the cord-free work area clear.
- Set only enough blade depth for the material, keep both hands in the intended grip positions and stand out of the blade path.
- Let the blade reach speed before entering the work and allow it to stop before setting the saw down.
Wear eye and hearing protection and use appropriate dust controls. Kickback can occur when the blade binds or the work shifts. Read the manual for the exact model; controls and guard procedures are not interchangeable.
Frequently asked questions
Is a faster no-load RPM always better?
No. RPM is one specification. Blade, motor behavior under load, material, depth and feed rate all affect the cut.
Does a bare tool include a battery?
Not here. DCS565B and XSS02Z exclude battery and charger; CR6413B-11 is a kit. Verify the seller’s exact package before ordering.
Were these circular saws tested by HandyTested?
No. This comparison is based on current primary manufacturer documentation.
