DeWalt 20V MAX* Brushless Cordless 4-1/2 in. Circular Saw

In my line of work, having a reliable and versatile tool can make all the difference. The DeWalt 20V MAX* Brushless Cordless 4-1/2 in. Circular Saw (model DCS571B) quickly became a standout addition to my toolkit. This compact circular saw boasts some impressive features, but it also has a few quirks worth noting.

First and foremost, the brushless motor is a game-changer. The power and efficiency it brings to the table are immediately noticeable. According to DeWalt, this saw can cut up to 369 linear feet of 3/4 in. OSB when paired with a DCB205 battery (sold separately). While I didn't measure the exact footage I cut, I can attest to its impressive battery life. Even with demanding tasks, the saw performed consistently well without frequent recharges.

One of the standout features is the removable auxiliary handle. This addition significantly improves control, especially when making more precise cuts. The hang hook is another thoughtful inclusion, offering convenience when you need to set the tool down between tasks. Speaking of convenience, the on-board blade key storage means you won't be scrambling to find the key when it's time to change the blade.

The finger trigger design is ergonomic, making the tool feel like an extension of your hand. This is particularly beneficial for those longer projects where fatigue can set in. The bevel gear design allows for cutting 2x material at 90 degrees and 1x material at 45 degrees, making it versatile for various applications.

Safety is always a priority, and the electronic blade brake provides peace of mind by quickly stopping the blade after releasing the trigger. The bevel lever is easy to use and makes adjusting for 45-degree cuts straightforward. Additionally, the on-board dust port is a nice touch for dust control, although I found that connecting a shop vac can be cumbersome due to the positioning of the dust port.

Now, let's talk about weight. At 88 ounces, this saw is not the lightest on the market, and it does feel hefty during extended use. For those with smaller hands or less upper body strength, this might be a drawback. I found it manageable, but it did take some getting used to. The balance, once you adapt, is quite good, especially when using a 5.0 Ah battery which seems to complement the tool's weight.

The cutting performance is where this saw truly shines. Whether tackling old deck boards or synthetic ones, it handled everything I threw at it without binding or stalling. The Diablo blade I used provided smooth, clean cuts, and the saw felt precise and easy to maneuver. The controls are well-laid out, making it user-friendly even for those less experienced with power tools.

However, not everything is perfect. The hex key holder, for instance, feels a bit loose and could easily let the wrench fall out during use. Another minor gripe is the dust port's design. While it does control dust fairly well, the positioning could be better. When hooked up to a shop vac, the hose tends to get in the way, making long cuts a bit of a hassle.

The saw's length at 17 inches also makes storage somewhat challenging, especially if space is tight. It fits well in my workshop, but for those with limited storage, this might be something to consider. Despite these minor issues, the overall build quality is solid, and it feels like a tool built to last.

One area where DeWalt could improve is the inclusion of accessories. The saw does not come with a dust bag, which would be a handy addition for those using it without a shop vac. Additionally, a laser guide could significantly enhance the tool's usability, especially for those precise cuts. It's surprising that such a feature isn't included or at least available as an optional accessory.

In terms of battery life, the tool performs admirably. I used it extensively with a 6-hour battery, and it lasted longer than I anticipated. DeWalt's 20V MAX* batteries are known for their quick charging, which is a definite plus. However, it's worth noting that the tool does not come with a battery or charger, so you'll need to factor that into your budget if you don't already own compatible batteries.

The saw's ability to cut through a variety of materials with ease makes it a versatile addition to any toolkit. From plywood to 2x4s, it tackled each task with precision and power. The compact size and cordless design make it ideal for quick, on-the-go cuts without the hassle of dragging out a larger corded saw.

In conclusion, the DeWalt 20V MAX* Brushless Cordless 4-1/2 in. Circular Saw is a robust and versatile tool that excels in many areas. While it has a few minor drawbacks, they are far outweighed by its performance, convenience, and build quality. If you're in the market for a compact circular saw that can handle a variety of cutting tasks with ease, this tool is a solid choice. I highly recommend it for both professionals and DIY enthusiasts looking for a reliable and efficient cutting solution.
