DeWalt DCS393B 20-Volt MAX Lithium Ion Circular Saw Review

In this review of the DeWalt DCS393B 20-Volt MAX Lithium Ion Circular Saw, we will provide you with all of the details that you need to make an informed buying decision. We will look at the various features of the saw, and also its advantages and disadvantages.

Some people are put off by cordless circular saws as they believe that they do not have the same kind of power that a corded saw provides. This is not the case with the DeWalt DCS393B circular saw. It is lightweight, and the 20V MAX battery makes it a lot more powerful than previous cordless models. This saw will not let you down, and you will be surprised how long the charged 3 AH battery will last.

Design And Features Of The DeWalt DCS393B Circular Saw

Ergonomics feature strongly with DeWalt tools, and the 20V circular saw range has had some changes here too. There is a rubber over mold on the handle and it has been designed so that it is easier to hold for longer periods of time. The handle has been made slimmer too.

The saw feels a lot more comfortable to handle, and this is partly due to the battery pack sliding in below the handle, rather than the old models where the battery was at the base of the handle. This circular saw is well balanced, and only weighs 7 pounds without the battery and 8.4 pounds with the battery installed.

The DeWalt DCS393B circular saw has also had an electronics upgrade. The trigger switch now has intelligent electronics built into it, which are designed to extend the life of the saw and the batteries. The electronics also prevent the saw from overheating, discharging deeply during use and overloading.

There have been quite a few changes to the older 18 volt circular saws. The new 20 volt range has more power, so that they can tackle those more heavy duty woodworking projects. When you use the new 20 volt saw you will find it difficult to tell it apart from a corded model. The up rated 20 volt battery provides at least 50% more run time than the previous lower voltage models did. This means higher work productivity for you due to less downtime.

All you have to think about is cutting the wood that is in front of you. You don’t need to give a second thought to slowing the cutting speed down, as you will no longer have to be concerned about the battery life.

The motor in the saw has a maximum 3700 RPM output, and this is actually higher than the current DeWalt corded circular saws. So you will get faster cuts, and difficult cuts just became a lot easier to make.

The DeWalt DCS393B has been primarily designed for right handed people as they are in the majority, but left handed people have not been left out. There is a safety cut off switch that can be used by either left or right handers. In fact you have to press the safety button and the trigger in order for the saw to operate.

For the right handed person, the motor will not be in the way when you are cutting which makes things a lot easier. It will be easy to see where the blade is cutting. The shoe of this DeWalt circular saw is made of magnesium and is lightweight and very strong. The shoe has a smooth bottom which enables a very easy glide over the wood that you are cutting.

A 16 tooth, 6½ inch blade, which is carbide tipped, is supplied with the circular saw. This blade is very good for general woodworking and it is surprisingly thin. If you need to use another blade then this is no problem, as the saw has a standard 5/8 inch arbor and will accept most blades.

With the standard blade you will be able to make a 2¼ inch depth of cut at 90°, and at 45° you will be able to make a 1 5/8 inch cut. You can use this DeWalt circular saw to make bevel cuts from 0° to 50°. All you need to do is tilt the saw and use the angle gauge to obtain the best accuracy.

There is a guard on the lower portion of the blade which is made from plastic. This guard will never get in the way, even if you are making long cuts or angled cuts.
