DeWALT DCS570 20v MAX XR 7-1/4 Inch Circular Saw Teardown and Review: Exploring Build Quality, Performance, and Components

Welcome back to another episode of Burton Builds, where we delve into the DeWALT DCS570 20v MAX XR 7-1/4 Inch Circular Saw. In this video, we will not be building something, but rather, we will be revisiting this circular saw to analyze its build quality and overall performance. Two viewers specifically commented on the build quality of the circular saw, so we decided to take it apart and examine its components. But before we do that, let’s discuss the performance of the saw so far.

The reviewer mentions that they have been using the circular saw for about four to five months and are generally satisfied with its performance. They have primarily used the 5 amp battery, although they mention that others have used the 2 amp and the flex volt 60 volt battery with less effective results. They note that the 5 amp battery seems to provide adequate power and runtime, comparable to the 60 volt 9 amp battery. However, they emphasize that the circular saw is not a precision instrument like a table saw, but rather designed for more general purposes.

Now, let’s move on to the teardown of the circular saw. Two viewers, internment77 and Alexandre, specifically commented on certain aspects of the saw’s build quality. Internment77 pointed out a plastic part, which holds the auger and the arbor bearing in place, expressing concern about its durability. Alexandre mentioned that the shoe, located on one side of the saw, appeared slightly misaligned. The reviewer investigates these concerns and measures the misalignment, confirming that there is approximately a 1mm offset. They note that this level of tolerance is acceptable for their purposes, considering the intended use of the circular saw.

Moving on to the teardown process, the reviewer begins by examining the blade guard, which is made of aluminum with a plastic center. They express a preference for the entire blade guard to be made of aluminum for increased durability. They note that the plastic center of the blade guard is a potential weak point that may break easily if the saw falls.

Next, the reviewer looks at the shoe, which is made of stamped aluminum and measures 4mm in thickness. They observe that the shoe is only supported in the front and is not as sturdy as it could be. This lack of support may contribute to the slight misalignment of the shoe. The reviewer offers their diagnosis but acknowledges that they are not an expert on the matter.

The reviewer proceeds to examine the gearbox, which is relatively small. They discover a substantial amount of grease inside the gearbox, which they believe to be beneficial for its smooth operation. They note that the gears are sintered metal and the plastic part that holds the bearing is a potential weak point. They express a desire for this part to be made of a more durable material, such as steel or aluminum.

Continuing with the teardown, the reviewer examines the motor, which they describe as fairly large and equipped with sensors. They highlight the presence of a brushless motor, which they believe contributes to the overall performance of the circular saw. They note the presence of a potting compound around the circuit board, preventing them from seeing its internal components. They also mention the presence of a switch mechanism and point out the lack of bellows on the shaft, which may allow dust to enter the switch over time.

The reviewer discusses the quality of the switch, noting that it is a different brand commonly used in DeWALT products. They appreciate the crimped wiring connections, which minimize the risk of dry solder joints. They also mention the presence of a locking mechanism on the switch, ensuring its stability during use.

In summary, the DeWALT DCS570 20v MAX XR 7-1/4 Inch Circular Saw offers satisfactory performance and build quality. While there are some potential weaknesses, such as the plastic parts and slight misalignment, these issues are within an acceptable range for the intended use of the circular saw. Overall, it provides a reliable tool for woodworking projects. If you are interested in more details about this circular saw, check out the review and unboxing video from five months ago.

Although the teardown process may reveal potential weaknesses, it is important to note that the reviewer is not an expert in tool disassembly. The purpose of the teardown was to better understand the build quality and components of the circular saw. Nonetheless, the DeWALT DCS570 20v MAX XR 7-1/4 Inch Circular Saw remains a solid choice for woodworking enthusiasts.
