  • As a cordless model, power may be limited


Rather than turning to somebody who can complete woodworking tasks for my personal projects, I have personally found it beneficial to start learning the trade on my own. With this motivation is the need to have the right tools to complete the job. One of the power tools that I knew I needed is a circular saw.

Compared to a standard saw, a circular saw has the capacity to cut with cleanliness and precision. As a power tool, it is also designed with convenience and ease of use in mind.

I just hoped I knew about the DEWALT DCS391B 20-Volt MAX Li-Ion Circular Saw when I was looking for options the first time. It seems that this option is equipped with features that I am looking for. I believe that this has the capacity to deal with various cutting tasks.

Who Is It For?

A circular saw like the DEWALT DCS391B model is ideal for woodworkers who need a dependable equipment that can deal with different types of cutting tasks. It is one that is not just meant for the use of skilled workers, but also ones who are still learning the ropes, so to say.

This power circular saw is an item that should be included in the arsenal of any carpenter or woodworker. Aside from its capabilities in offering precision and accuracy, it also provides convenience since everything else is pre-set for our task.

Buyer's Guide

Is Buying a Circular Saw Worth it?

This is one question that you may ask in your mind. After all, with the presence of standard tools which you may already be more familiar with, being introduced to a new power tool can bring some doubts. When it comes to purchasing a circular saw, however, there are certain advantages that you can expect. Here are some of them:

  • A Good Investment

If you need to constantly work with metal, plastic or wood, getting a circular saw can prove to be a good investment on your part. Aside from the fact that it is relatively easy to use, it can also work in revolutionizing the way in which you complete your cutting tasks. Rather than spending more time when using a standard tool, a power circular saw can also cut the time, which also translates to savings on your part.

  • Different Purposes of Use

If you think that this tool is only designed to deal with cutting, think again. As a matter of fact, it can also be used for other purposes, such as for decorative punching. All you need to do is to perform some technique modifications and you can start creating those plunge and bevel cuts, using this very same tool, without necessarily changing the blade.

  • Portability

Circular saws are typically designed with portability in mind. This is the reason why you will see that most manufacturers introduce the weight and the size of their models, because they know that it can serve as a main selling point of their product. When checking for options, take into consideration your needs in terms of portability, and choose the best model that can offer you convenience.

Features to Look for in a Circular Saw

When looking for a good circular saw that you can purchase, there are certain features that should be taken into consideration, as they are the ones that either make or break the capability of a certain model.

  • Saw Blades

No doubt, a saw is nothing without its blades. Therefore, it is one of the most important features that you need to look into. It is not just about choosing the right blade, but also making sure that it is sharp enough to complete the tasks required. The blades can come in different types, including steel, carbine, tile, and masonry.

  • Shaft Locks

A shaft lock is one of the features implemented for security. This typically comes in the form of a button that can be pressed in order to hold the saw blade in place. As such, you can now change the blade easily. Most professional grade circular saws have this type of feature.

  • Electric Brake

Not all models come with an electric brake, but this feature is quite helpful in terms of safety. It works by stopping the motor in approximately two seconds right after the trigger is released. A model that does not have an electric brake typically takes about 15 seconds to completely stop. This reverses the electricity flow going back to the motor, thus protecting your fingers and limbs from getting hurt.
