When you compare the craftsman v20 rp cordless circular vs v20 cordless circular saw, you see two distinct approaches to portable cutting. Both tools run on the same 20V MAX platform, allowing you to share batteries between them. The main difference lies in the blade size and motor type. One model offers a larger 7-1/4-inch blade with a brushless motor for heavier work. The other features a compact 6-1/2-inch design with a brushed motor for lighter tasks. Your choice depends on the material thickness you cut most often.
Key differences

|---|---|---|
| Blade Diameter | 6-1/2 inch | 7-1/4 inch |
| Motor Type | Brushed | Brushless |
| No-Load Speed | 4,000 RPM | not listed |
| Weight | 10.2 pounds | 9.3 pounds |
| Max Bevel | 50 degrees | 56 degrees |
Which one should you choose?
Choose CRAFTSMAN V20 6-1/2-Inch Cordless Circular Saw Kit if
- You need to cut standard 2x material and prefer a lighter, more compact tool.
- You want a kit that includes the battery and charger right out of the box.
- You value a high no-load speed of 4,000 RPM for fast cross-cutting.
Choose CRAFTSMAN V20 Brushless 7-1/4-Inch Circular Saw if
- You require the extra cutting depth of a 7-1/4 inch blade for thicker lumber.
- You want a brushless motor for longer runtime and more power on demanding jobs.
- You need a tool that weighs less at 9.3 pounds for overhead or extended use.
Verdict: The CMCS500M1 is the better choice if you need a complete kit with a battery and charger for general carpentry. The CMCS551B is superior for users who need deeper cutting capacity and the efficiency of a brushless motor. Select the model that matches your typical material thickness and whether you already own V20 batteries.
CRAFTSMAN V20 Circular Saw Comparison
Blade Diameter
The CRAFTSMAN V20 RP Cordless Circular Saw features a larger 7-1/4 inch blade, while the standard V20 model uses a 6-1/2 inch blade. A larger blade allows for deeper cutting capacity, which is useful for thicker stock. The 7-1/4 inch option provides more material removal per pass. The 6-1/2 inch blade is standard for many portable tasks and offers slightly less weight and bulk. You should choose the larger blade if you frequently cut thick lumber or need maximum depth. The smaller blade is sufficient for standard framing and crosscuts. This difference defines the primary cutting envelope for each tool.
No-Load Speed
The standard CRAFTSMAN V20 Cordless Circular Saw Kit delivers a no-load speed of 4,000 RPM. The V20 RP model does not list a specific RPM value in its published specifications. Higher RPM generally means faster cutting through material. The 4,000 RPM figure indicates an aggressive cutting speed for the standard model. Without a stated speed for the RP model, you cannot directly compare their cutting velocity. You may need to assume similar performance or check other reviews. The standard model provides a clear speed metric, while the RP model leaves this detail unspecified.
Weight
The CRAFTSMAN V20 RP Cordless Circular Saw weighs 9.3 pounds. The standard V20 Cordless Circular Saw Kit weighs 10.2 pounds. The RP model is lighter by nearly one pound. A lighter tool reduces fatigue during overhead work or extended use. The standard model is slightly heavier, which might provide more stability for some users but increases hand strain. The weight difference is noticeable but not drastic. You should consider the RP model if you prioritize maneuverability and reduced weight. The standard model is acceptable if you do not mind the extra pound.
Bevel Capacity
The V20 RP model offers a maximum bevel of 56 degrees with positive stops at 22.5 and 45 degrees. The standard V20 model pivots up to 50 degrees for angled cuts. The RP model provides a greater range of motion for complex joinery or angled cuts. The positive stops on the RP model help ensure accuracy at common angles. The standard model stops at 50 degrees, which is sufficient for most standard bevels. If you need cuts steeper than 50 degrees, the RP model is necessary. Otherwise, both tools handle basic angled cuts well.
Motor Type
The CRAFTSMAN V20 RP Cordless Circular Saw is equipped with a brushless motor, which offers up to 75% more power and runtime. The standard V20 Cordless Circular Saw Kit does not specify its motor type in the provided data. Brushless motors are generally more efficient and durable. The RP model likely provides better performance for demanding jobs due to this feature. Without confirmation for the standard model, you cannot be certain of its motor construction. The RP model has a clear advantage in technology and efficiency claims. Choose the RP model for longer runtime and power.
Which CRAFTSMAN Model Fits Your Needs
Heavy-duty users needing deeper cuts
You should choose the CRAFTSMAN V20 RP Cordless Circular Saw if you frequently cut thick lumber. Its 7-1/4 inch blade offers greater depth capacity than the 6-1/2 inch option. The brushless motor provides up to 75% more power and runtime. This model also includes a bright LED to illuminate your work line and positive bevel stops at 22.5 and 45 degrees for precision.
Users wanting a complete ready-to-use kit
Select the CRAFTSMAN V20 6-1/2-Inch Cordless Circular Saw Kit if you need a tool that is ready immediately. This model includes both the battery and charger, so you can start cutting without buying extras. It delivers 4,000 RPM for aggressive fast cutting. The compact design helps reduce fatigue, and the contoured over-molded handle adds comfort during extended use.
Professionals prioritizing weight and portability
If you carry your tool up ladders or across job sites daily, the CRAFTSMAN V20 RP Cordless Circular Saw is lighter at 9.3 pounds. The standard V20 model weighs 10.2 pounds. Although this version is tool-only, its brushless motor optimizes performance with a 4.0ah battery. The VERSATRACK compatibility allows you to hang it securely on wall organization systems when not in use.
