It includes a tool-free depth adjustment and blade change, which enhances user convenience. The saw is powered by a 20V MAX* POWERCONNECT battery system, allowing compatibility with multiple tools, though the battery must be purchased separately.
Overview of DEWALT 7-1/4-Inch Circular Saw
The DEWALT 7-1/4-Inch Circular Saw is a powerful corded option priced at $135.00, offering robust features for more demanding applications. Weighing only 8.8 lbs, it is one of the lightest in its class. The 15 amp motor provides enough power to handle tough cutting tasks, and its 57-degree bevel capacity offers more versatility than the BLACK+DECKER saw. The integrated dust blower function ensures a clear line of sight during cuts, making it an excellent choice for both professional and serious DIY work.
Performance and Cutting Ability
In terms of performance, the DEWALT 7-1/4-Inch Circular Saw has a clear edge with its 15 amp motor, capable of tackling tougher materials and projects. In comparison, the BLACK+DECKER saw, while sufficient for light to medium tasks, may struggle with more demanding cuts due to its smaller blade and motor capabilities. The DEWALT's 2-9/16 inch depth of cut capacity allows for versatility in applications, whereas the BLACK+DECKER's design is more suited for basic DIY projects. This difference makes the DEWALT a better choice for those who need a reliable tool for heavier workloads.
Portability and Design
The BLACK+DECKER 20V 5-1/2" Cordless Circular Saw excels in portability, being cordless and compact, which allows for easy maneuverability without the constraints of a power cord. This makes it ideal for outdoor or job site use where power outlets may not be available. On the other hand, the DEWALT saw, while corded, is designed to be lightweight at 8.8 lbs, ensuring that it remains user-friendly despite its plugged-in nature. The DEWALT’s durable aluminum base provides stability and accuracy, making it a solid choice for precise cuts, while the BLACK+DECKER offers tool-free adjustments for quick changes during tasks.
User Experience and Convenience
User convenience is a significant factor in both models. The BLACK+DECKER saw features a tool-free depth adjustment and blade change, allowing users to make quick modifications without additional tools. This feature is particularly beneficial for DIYers who may not have a full toolbox readily available. In contrast, the DEWALT saw boasts an anti-snag ball bearing lower guard, ensuring smooth and reliable operation, even in harsh environments. Additionally, the on-board blade wrench storage in the DEWALT allows for easy access and less downtime during projects.
Price Comparison
Price is a crucial factor when choosing between these two circular saws. The BLACK+DECKER 20V 5-1/2" Circular Saw is priced at $74.99, making it about 44% cheaper than the DEWALT 7-1/4-Inch Circular Saw, which costs $135.00. While the lower price point of the BLACK+DECKER may attract budget-conscious consumers, it is essential to consider the performance capabilities and features that come with each model. For users requiring a tool for heavy-duty applications, the investment in the DEWALT may be justified despite the higher price.
Brand Reputation and Sales Rank
Both BLACK+DECKER and DEWALT are respected brands in the power tools market, but they cater to slightly different audiences. The BLACK+DECKER 20V saw has a sales rank of 102,120, indicating it is a popular choice among casual users and DIYers. In contrast, the DEWALT saw enjoys a significantly better sales rank of 18,265, reflecting its appeal among professionals and those demanding higher performance from their tools. This difference in sales rank could suggest that the DEWALT saw is perceived as a more reliable option for serious applications.
Which should you buy?

If you are a casual DIYer looking for a lightweight and budget-friendly option, the BLACK+DECKER model is an excellent choice.
