Maybe you have used a corded circular saw before, but now cordless circular saws are becoming more and more popular, because the battery technology has improved and batteries are becoming more powerful than before. Therefore, more and more manufacturers have created their cordless versions for more convenient use. The higher voltage and large capacity can make a cordless one have the same experience as a corded one.
Early cordless circular saws only support a 3-1/2 inch blade due to its lower voltage -only 9.6v. And the batteries are Ni-Cads. Now the latest versions use Lithium-Ion batteries which are widely used in many fields and can provide the best power, making cordless circular saws can even support 6-1/2 inch blade. The Lithium-Ion batteries have a large capacity and can be charged quickly, which is important because you don’t need to wait for a long time to charge the batteries full and you can get back on your job quickly. Although the blade is not as big as a corded one (7-1/4 inch blade), there is no big difference between them. They are powerful enough to cut not only plywood but also standard dimensional lumber for construction.
Here, we have done adequate research and have picked out some best Cordless Circular Saw, according to their weight, comfort, convince, performance and customer reviews. If you happen to want to buy one, reading these Circular Saw reviews can help you choose the right one for your job.
Not all of them have two batteries, so knowing how these batteries will be sold is important. Since Li-Ion batteries can cost over $100 each, doing cost comparisons is a good habit.

CIRCULAR SAW Buying Guide
When it comes to buying the best circular saw, there are some features you should pay more attention to. The following features should be taken into account.
1. Speed Control
Well, how to measure the power of a circular saw? The answer is its motor strength and how many revolutions the blade can spin in a minute. We can use the number of RPM to measure its power. The RPM is short for revolutions per minute. In order to get a smoother cut, they tend to use a higher power rating. Generally, the motor power can be low to 500 watts and high to 1500 watts. Of course, the higher the wattage is, the more RPM it can offer. And this also means you will get more power and speed control. More power means you can run much bigger blades. For example, if you choose a more powerful saw, you will get bigger hence and blades. And you can use it to make a maximum cut depth, about 65mm. A powerful model allows you to easy control it to cut even tough materials. Therefore, the blade speed is the first factor you need to consider before making a purchase decision.
2. Bevel Capability
An ideal circular saw should allow you to tilt it to adjust its base, and this can help to get angled cuts. An adjustable base plate should be included. This feature means the circular saw can be easily angled at the range from 0 to 45 degrees. And modifying the cutting depth becomes easy. Built-in adjustment options mean both accuracy and efficiency can be improved.
The one you choose should come with a very clear view of the cut line. And being left or right-handed should also be taken into account. The saw you choose should have notches and blades which should enhance visibility.
4. Depth Adjustment Lever
A good circular saw also allows you to adjust its cutting depth, so you can use it to cut different kinds of materials with ease and you can get different kinds of thickness. And this can give you good visibility and makes it easy to access. Thanks to the outboard levers, your trigger hand can be kept in place all the time. Therefore, you can always work on the locking blade depth into place. And tucked between the handle and blade guard can be inboard levers. This is a bit difficult to operate. Therefore, thick and rounded levers are the best choice. And they should be covered in rubber, which enables easy and safe grasping. The depth scale should be read with ease and can be marked distinctly. Engraved markings and cast numbers are much better than stickers because of their permanent features.
5. Electric Brake
The electric brake is able to stop the motor in less than 2 seconds, once the trigger is released. On the contrary, if you choose a circular saw without an electric brake, this process may need about 10 to 15 seconds. The electric brake will reverse the electricity flow towards the motor. On the market, most models offer electric brakes, because the electric brake offers convenience and can prolong the life of your saw. And the quick stop can also protect you and avoid getting hurt.
6. Blade Guard
When you don’t need to use the saw, the saw guard can cover the blade and protect it. And it is also a safety feature. When you need to use your saw, the guard will retract to reveal its blade. Sometimes, it will be a frustration experience because of a stuck blade guard. Those with sharp or rough edges are most likely to become stuck when it comes to cut regular wooden surface or cutting in angels. Therefore, a circular saw with a large lobe above the guard’s leading edge will be perfect.
7. Dust Blower
When a circular saw is working, massive dust will be produced. Therefore, a circular saw with a dust bag is ideal, or the saw with a vacuum cleaner connection is much better. A dust blower is able to improve visibility, because the dust can be removed from its cutting lines. Most models come with a dust port which can be connected to a vacuum or just a dust bag, so the dust management becomes much easier.
8. Weight and Balance
After a long time use, you may feel tired. In this situation, the balance becomes more important than weight. The trigger must have enough space even if you are wearing gloves. And you also need to consider where you will use your saw. For example, most models are perfect for overhead work, but they are not ideal for long cuts with plywood.
9. Other Extra Features
For superior accuracy, you can choose a circular saw with a built-in laser which can enable you to have more accurate cuts, improving your efficiency. For cordless circular saws, the batteries also really matter. The quality should be high quality and the capacity should be large enough, and the charging time should be shorter.
