Overview of the BLACK+DECKER and SKILSAW Circular Saws
The BLACK+DECKER 20V MAX POWERCONNECT Cordless Circular Saw is priced at $95.00, making it significantly more affordable than the SKILSAW SPT77W-01, which costs $181.28. This pricing difference of about 48% suggests that the BLACK+DECKER model is aimed at DIY enthusiasts and casual users, while the SKILSAW may appeal more to professionals or those needing more robust features.
The BLACK+DECKER saw is designed for versatility in DIY tasks, featuring a 5-1/2 inch blade that allows for fast cutting. In contrast, the SKILSAW boasts a larger 7-1/4 inch blade, ideal for heavier-duty applications. Each saw brings distinct strengths to the table, catering to different user needs.
Design and Build Quality
In terms of design, the BLACK+DECKER saw is compact and lightweight, suitable for home use and less demanding tasks. Its emphasis on ease-of-use features, such as tool-free depth adjustment and blade changes, makes it user-friendly. The saw also includes a pivoting shoe for improved control, enhancing the overall user experience.
On the other hand, the SKILSAW's 14.2 lbs. construction is designed for durability and professional use, emphasizing a robust build that can withstand jobsite conditions. The aluminum construction contributes to its longevity, while the integrated saw hook allows for safe placement on rafters. Thus, while BLACK+DECKER focuses on versatility and ease, SKILSAW prioritizes strength and reliability.
Performance and Cutting Ability
When comparing performance, the BLACK+DECKER saw features a powerful 20V MAX battery system, ensuring adequate power for standard cutting tasks. The saw's ability to handle a variety of DIY projects is enhanced by its fast-cutting blade and bevel detents for angled cuts at both 45 and 90 degrees.
Conversely, the SKILSAW excels in heavy-duty applications, thanks to its 15-amp Dual-Field motor that increases cooling and extends tool life. This motor is designed specifically for saws, making it ideal for contractors and serious DIYers who require reliable performance over extended periods. The 51° bevel allows for a wider range of cuts, making it a versatile tool for professional projects.
Battery Life and Power Options
In terms of power options, the BLACK+DECKER saw operates on a 20V MAX POWERCONNECT battery, which is rechargeable and compatible with other tools in the POWERCONNECT system. This feature is particularly appealing for users who already own other BLACK+DECKER tools, as it reduces the need for multiple battery types.
Conversely, the SKILSAW is corded and relies on a consistent power source, which can be advantageous for prolonged use without worrying about battery depletion. While the BLACK+DECKER offers the convenience of cordless operation, the SKILSAW's corded design ensures it can handle demanding tasks without interruptions, making it a strong choice for professional applications.
Ease of Use
The BLACK+DECKER saw shines in its user-friendly design, featuring tool-free adjustments for both depth and blade changes. This aspect is especially beneficial for those who may not have extensive experience with power tools. Additionally, the saw's lightweight design contributes to reduced user fatigue, allowing for longer periods of use without discomfort.
In contrast, the SKILSAW, while slightly heavier, offers its own ease-of-use features, such as the Cut Ready depth-of-cut system, which allows for quick and accurate depth adjustments. The saw's lightweight construction compared to its predecessor also aids in reducing user fatigue, although it may still be less user-friendly for casual users compared to the BLACK+DECKER model.
Safety Features
Safety is paramount in power tools, and both the BLACK+DECKER and SKILSAW include features aimed at protecting the user. The BLACK+DECKER saw includes a pivoting shoe that provides enhanced control during cuts, reducing the risk of accidents. Its lightweight design also aids in maneuverability, contributing to overall safety.
The SKILSAW stands out with its integrated saw hook, designed for safe placement on rafters, preventing potential accidents when the saw is not in use. This thoughtful design feature caters to the needs of professionals who require safety while working at heights or on unstable surfaces, enhancing its appeal for job site use.
Price Comparison
The BLACK+DECKER is priced at $95.00, making it a more budget-friendly option compared to the SKILSAW's price of $181.28. This represents a difference of about $86, or roughly 48%, making the BLACK+DECKER a compelling choice for those looking for an economical circular saw for home projects or light usage.
In contrast, the SKILSAW's higher price reflects its professional-grade capabilities and durability. It ranks higher on bestseller lists, indicating its popularity among serious users willing to invest in a quality tool. For those whose projects demand more power and reliability, the SKILSAW may justify its higher cost.

If you are a casual user or a DIY enthusiast looking for a versatile, easy-to-use saw at a reasonable price, the BLACK+DECKER is an excellent choice.
