This DEWALT DCS391B 20V MAX Circular Saw review details my extensive experience with this tool, highlighting its strengths and weaknesses after years of use.
For years, I struggled with a frustratingly underpowered circular saw, hindering my DIY projects and causing significant delays. The prospect of tackling larger projects felt daunting, knowing my old saw couldn’t handle the demands. A reliable, powerful saw wasn’t just a convenience; it was a necessity to complete projects efficiently and safely. A new saw would have solved this problem tremendously.
- 5150 RPM motor of DEWALT circular saw delivers power and speed to make the most demanding cuts with ease
- High strength and lightweight magnesium shoe of the corded circular saw provides jobsite durability for long-term cut accuracy
- Optimized rubber overmolded comfort grip of the compact circular saw delivers optimal balance and control
Factors to Consider Before Buying a Circular Saw
Circular saws are essential tools for various woodworking tasks, from cutting lumber for framing to making precise cuts in plywood. The ideal circular saw will depend on the user’s needs and the types of projects they undertake. Serious professionals requiring heavy-duty use will have different needs than DIY enthusiasts. Someone working with intricate details might prefer a smaller, more maneuverable saw, while a contractor needs durability and power to cut through thick materials quickly. Before purchasing, consider the following:
- Power Source: Corded saws offer consistent power but limit mobility. Cordless models provide freedom but require charged batteries. Consider the amperage of the battery (higher amperage generally means longer run time) for cordless options.
- Blade Size: A larger blade cuts faster through thicker material but is less maneuverable. Smaller blades are easier to handle but require more passes for larger cuts.
- Bevel Capacity: The angle at which the blade can tilt, essential for angled cuts.
- Weight and Ergonomics: A lighter saw reduces fatigue, especially during prolonged use. Look for comfortable grips and well-balanced design.
- Budget: Circular saws range in price considerably. Set a budget before you start shopping.
Those who only need to perform occasional, light-duty cuts might find a less expensive, basic model suitable. If frequent, heavy-duty cuts are required, then investing in a higher-quality, more robust saw, such as the DEWALT DCS391B 20V MAX Circular Saw, is worthwhile.
- 2.8-amp motor rotates the blade up to 2500 feet per minute
Introducing the DEWALT DCS391B 20V MAX Circular Saw
The DEWALT DCS391B 20V MAX Circular Saw is a cordless circular saw boasting a powerful 5150 RPM motor, a lightweight magnesium shoe, and a comfortable rubber grip. It promises smooth, accurate cuts with minimal effort, and it’s designed for cutting wood. Compared to previous DEWALT models, this saw features a brushless motor for increased efficiency and runtime. While it doesn’t directly compete with the market leader in terms of sheer raw power, its combination of power, lightweight design, and precision makes it a formidable contender. This saw is perfect for DIY enthusiasts and professional contractors who need a versatile and reliable tool for a wide range of woodworking projects. It’s not, however, ideally suited for extremely heavy-duty industrial applications needing the power of a much larger saw.
- Pros: Lightweight, powerful motor, accurate cuts, comfortable grip, 0-50 degree bevel capacity.
- Cons: Battery sold separately (requires additional purchase), safety switch design might take some getting used to, relatively higher price point compared to some basic models.
Features and Benefits of the DEWALT DCS391B
Powerful 5150 RPM Motor
The heart of this DEWALT DCS391B is its 5150 RPM motor. This translates to efficient cutting, even through dense materials. I’ve used it to cut through multiple sheets of plywood without any issues, something my previous saw struggled with. This speed significantly reduces the time needed for large projects.
Lightweight Magnesium Shoe
The magnesium shoe is a game-changer. It makes the saw incredibly lightweight without sacrificing durability. This is a huge advantage during extended use; reduced fatigue means more precision and a higher quality of work. I’ve used this saw for hours at a time with minimal discomfort.
Comfortable Rubber Overmolded Grip
The rubber grip provides exceptional control and reduces vibration. It’s a simple feature, but it makes a significant difference in the overall user experience. The comfortable grip ensures accurate cuts and minimizes hand fatigue during prolonged use.
0-50 Degree Bevel Capacity
The 0-50 degree bevel capacity provides flexibility for various applications. I’ve used this feature extensively for creating angled cuts on numerous projects. It adds versatility beyond simple straight cuts, opening possibilities for more complex designs.
Brushless Motor Technology
The brushless motor is a key feature that contributes to the saw’s longevity and efficiency. It runs cooler, is more energy-efficient, and requires less maintenance than brushed motors, translating into a longer lifespan for the tool. I appreciate this feature, knowing my investment will last for many years.
6-1/2-Inch Carbide-Tipped Blade
The carbide-tipped blade provides clean, precise cuts and ensures a longer life than standard blades. The ability to cut through 2x materials at 90 and 45 degrees is a testament to the blade’s quality and sharpness. I have consistently been impressed with the clean cuts, minimizing the need for additional sanding or finishing.
User Experiences with the DEWALT DCS391B
Many online reviews echo my positive experience. Users praise its power, lightweight design, and precision cutting. Many describe it as a reliable and durable tool that consistently performs as expected, whether used for DIY projects or more demanding professional work. While some users have noted the need to purchase a battery separately, the overall consensus is that this is a worthwhile investment.
Final Verdict: A Powerful and Reliable Choice
The DEWALT DCS391B 20V MAX Circular Saw has significantly improved my DIY projects. The initial problem of an underpowered saw is now a distant memory. The combination of power, lightweight design, and precision cutting makes this a truly exceptional tool. It’s well-built, durable and a pleasure to use. While the battery isn’t included and the safety switch requires adjustment, these are minor drawbacks compared to its overall performance and value.
