Updated July 2026 — full head-to-head comparison.
Overview of the Ryobi One P505 and Skil 20V Circular Saws
The Ryobi One P505 is priced at $44.89, while the Skil 20V Circular Saw Kit is significantly more expensive at $79.00, making the Ryobi about 43% cheaper. Both saws are designed for wood cutting but come with different features and capabilities. The Ryobi model is a standalone tool requiring a compatible battery, while the Skil model includes a battery and charger, adding value to the overall package.
Power and Performance Comparison
In terms of performance, the Skil 20V Circular Saw boasts a powerful brushless motor that delivers up to 5,500 RPM, compared to the Ryobi's 4,700 RPM. This performance difference may lead to faster cuts, especially in challenging materials. The Skil saw's motor allows for up to 105 cuts in 2x4 pine on a single charge, showcasing its efficiency. The Ryobi, while slightly less powerful, still provides adequate performance for household woodcutting tasks.
Design and Ergonomics
The Skil 20V Circular Saw features a compact, ergonomic design with a blade-left orientation, enhancing visibility of the cut line. This design is particularly beneficial for detailed work. On the other hand, the Ryobi One P505 incorporates a rubber grip that provides excellent handling and control, aided by an extra side handle for improved stability. While both saws are designed with user comfort in mind, the Skil’s design may offer superior visibility during cuts.
Safety Features
When it comes to safety, the Skil 20V Circular Saw includes an electric brake that stops the blade quickly between cuts, enhancing user safety during operation. This feature is particularly useful for preventing accidents and ensuring quick transitions between cuts. The Ryobi One P505 does not explicitly mention safety features like an electric brake, which may be a consideration for users prioritizing safety.
Battery and Runtime
The Skil Circular Saw comes with a PWR CORE 20 2.0Ah lithium battery and a charger, which provides additional convenience for users who may not already own compatible batteries. The built-in battery technology is designed to offer longer runtime and improved battery life. In contrast, the Ryobi One P505 operates on Ryobi's 18V battery system, but these batteries are sold separately, potentially increasing the overall cost for users who need to purchase them.
Additional Features
Both saws have unique features that cater to different user needs. The Ryobi One P505 includes a transparent lower guard for enhanced visibility during cuts, which may appeal to DIY enthusiasts looking for precision. Meanwhile, the Skil Circular Saw features a shadow line indicator created by an innovative LED, providing an additional layer of visibility for the cut line. These thoughtful features highlight the strengths of each model in enhancing user experience.
Brand Reputation and Sales Rank
In terms of sales rank, the Ryobi One P505 holds a rank of 18,485, indicating a relatively strong presence in the market. The Skil 20V model has a sales rank of 41,452, which suggests it may not be as popular among consumers. This difference in popularity could reflect user preferences, brand loyalty, or perceived reliability between Ryobi and Skil products.
Which should you buy?
Choosing between the Ryobi One P505 and the Skil 20V Circular Saw ultimately depends on your specific needs. If you prioritize cost and already own compatible Ryobi batteries, the Ryobi One P505 at $44.89 is a great choice for basic woodcutting tasks. However, if you seek higher performance and additional features like an electric brake and included battery, the Skil 20V Circular Saw Kit at $79.00 may be worth the investment, especially for more frequent or demanding projects.
