Price Comparison
The FLEX 24V Brushless Cordless 6-1/2-Inch In-Line Circular Saw is priced at $177.66, making it about 31% cheaper than the Milwaukee 2732-20 M18 Fuel 18 Volt Lithium-Ion 15 Amp 7-1/4 Inch Cordless Circular Saw, which retails for $256.99. This significant price difference may be a deciding factor for budget-conscious buyers. While the FLEX saw offers a more economical option, the Milwaukee tool's higher price may reflect its additional features and performance capabilities. The FLEX also boasts an average price of $188.38 over the last 90 days, indicating its pricing stability, while the Milwaukee's average price is slightly higher at $263.23.
Features and Functionality
The FLEX saw is designed with the world's first in-line circular saw design, providing superior balance and visibility on both sides of the blade, which enhances cutting accuracy. It features a sensor-free brushless motor that optimizes efficiency and power. On the other hand, the Milwaukee saw comes equipped with a powerful POWERSTATE Brushless Motor, delivering performance comparable to a 15 Amp corded saw while being rechargeable. Additionally, the Milwaukee model can make up to 750 cuts per charge, which is impressive for heavy-duty tasks. Both tools are designed for durability, but the FLEX's unique design may offer advantages in precision cutting.
Cutting Capacity
When it comes to cutting capacity, the FLEX saw can cut through 3x lumber in a single pass with a depth of cut of 2-9/16 inches. This capability is particularly beneficial for those who need to make deeper cuts quickly. The Milwaukee saw, with its 7-1/4-inch blade, is also designed for heavy-duty applications, but specific depth of cut specifications are less detailed in the provided data. Thus, while the Milwaukee is capable of handling tough materials, the FLEX offers a clear advantage in maximum cutting depth, which can enhance its utility in various scenarios.
Runtime and Battery Performance
The FLEX saw boasts exceptional runtime, achieving up to 430 cuts in 2x4 lumber with a 5.0Ah battery. This impressive performance is complemented by the FLEX Advantage of faster charging with dual fan chargers. In contrast, the Milwaukee tool, while it does not specify the number of cuts per charge, emphasizes its ability to outperform a corded saw in terms of power and efficiency. It is vital to consider that users of the FLEX will need to purchase batteries and chargers separately, while the Milwaukee’s integrated system may provide more convenience for users already invested in the M18 ecosystem.
Design and Build Quality
The design philosophy behind both saws reflects their intended user base. The FLEX saw’s in-line design offers advantages in visibility and balance, making it a suitable choice for precision work. Additionally, it is built around an intelligent sensor-free brushless motor for optimized performance. The Milwaukee saw, with its magnesium shoe and guards, is designed for maximum durability, catering to professionals who require rugged tools. The integrated rafter hook and dust port on the Milwaukee also enhance its usability on job sites, making it a versatile option for contractors.
User Experience and Ease of Use
User experience plays a crucial role in the effectiveness of these circular saws. The FLEX saw’s built-in LED light illuminates the workpiece, enhancing visibility for precise cuts. Its ergonomic design is aimed at reducing user fatigue during extended use. The Milwaukee saw also features an LED light, which, combined with its electric brake for immediate blade stopping, contributes to a safer and more efficient user experience. Both tools are equipped with features that aim to enhance usability, but the FLEX’s design may offer a slight edge in terms of comfort for prolonged tasks.
Brand Reputation and Reliability
Both FLEX and Milwaukee are recognized brands within the power tool market. The FLEX saw has a sales rank of 108,816, indicating a growing presence in the market, while the Milwaukee saw has a significantly better sales rank of 70,058, suggesting a strong reputation and reliability among users. Milwaukee’s long-standing history in the industry and its focus on durable, high-performance tools contribute to its credibility. The FLEX saw, while innovative, is still establishing its reputation, which may impact a buyer's decision when considering brand reliability.
Which should you buy?
Choosing between the FLEX 24V Brushless Cordless 6-1/2-Inch In-Line Circular Saw and the Milwaukee 2732-20 M18 Fuel 18 Volt Lithium-Ion 15 Amp 7-1/4 Inch Cordless Circular Saw ultimately depends on your specific needs and preferences. If budget is a primary concern, the FLEX is a more economical choice, offering unique design features and substantial runtime for the price. However, if you’re looking for a robust, high-performance tool that has proven reliability and superior cutting capabilities, the Milwaukee may justify its higher price. Consider your typical projects, preferred design features, and whether you require additional battery systems when making your decision.
