Best Cordless Circular Saw Buyers’ Guide 

Getting the right cordless circular saw can be a daunting job even when you already know the technical features of some of the leading brands that we have presented in this guide.

However, we have assembled some f the top features that we believe will help you make the best purchase decision of the best cordless circular saw. The various features include but not limited to;

Cutting Depth and Speed

The maximum depth at which a blade can cut, and the rotation speed determines the saw’s capability. Usually, you can use the indicated maximum cutting depth to determine the maximum width of planks that you can use the saw to cut.

It is possible to adjust the cutting depth depending on the requirements of your job. The maximum depth of cut varies with the beveling angle (it is usually at the highest when the angle is 90 degrees). Most brands can cut up to a depth of 2 inches at 90 degrees.

The speed of any circular saw is usually indicated in the number of revolutions per minute. The higher the RPM figure indicated on a saw, the faster and the most convenient the tool can cut through different materials.

Also, the RPM figure can be a good indicator of the kind of job that the saw can be used for. For example, saws with low RPM values that range from 3,500 to 4,000 are suitable for occasional use, while brands with RPM values of 5,000 to 6,000 are ideal for heavy-duty work.

Battery Life 

The battery longevity is a critical factor that you should consider when purchasing a cordless circular saw. Cordless circular saws rely on charged batteries to deliver power to the blade during usage. For you to work for a long time, the battery must have a corresponding long life.

Manufacturers typically include a 20V or 18V label on their brands. However, the best cordless circular saw that carries a 20V tag is not necessarily more potent than an 18V label. However, the higher the battery voltage, the more power is the saw.

Also, the tag indicates the initial battery voltage when the saw is not under load. The life of the battery is inversely proportional to the speed. If you set your blade speed to the maximum, then the rate of battery drain increases.

Portability 

The best cordless circular saws should be highly portable. However, various components like the battery, size of the blade, and other features integrated on the models determine the total weight of the saw.

Saws that carry large batteries and other advanced components tend to be heavier than those with only cointegrated on essential elements and functionalities.

The best way of determining the portability of a saw is by looking at its power-to-weight ratio. Saws with large power capacity are more massive than those with low power capacity.

Also, you can consider the dimensions and weight of the saw. Many saws fall within the weight category of 6 to 7lbs.
Whereas big saws may have the power to handle big jobs, using them for long can increase fatigue.

Lighter saws, on the other hand, offer you a more excellent feeling of control and flexibility. It is easy to control the angles of your cuts and work for long when you are using a lightweight saw.

Blade 

Consider three critical features of a blade before you settle on the right cordless circular saw: the size, number of teeth, and material used to make the teeth.

The size of the blade determines the level of power you will work with while using the saw. The size of the blade varies from 6-½ inches to even 7-¼ inches.

The number of teeth determines how smooth the cut is. Blades with few teeth can effectively cut through sturdy materials such as different types of hardwood.

Blades with a high number of teeth produce smoother cuts than those with few teeth.

Although all blades are made of steel, some manufacturers coat the teeth with such materials as carbide, titanium or diamond. The coating of blade teeth increases durability and not performance. Instead, the coatings reduce the wear rate of the teeth, thus increasing the length of life of the saw.

Bare tool or Kit

Cordless circular saws are available either as bare tools (without a battery and charger) or kits (complete with a battery or charger).

The most important thing to consider when buying a bare tool saw is whether you can access compatible batteries and chargers.

Manufacturers ensure that batteries are compatible with all brands of their saws under a series.

How to use Circular Saws to cut wood

Conclusion 

If you are looking for a basic cordless circular saw for occasional home-based use, then the Milwaukee M18 2630-20 or the Ryobi P508+18V Lithium-Ion brand will be ideal. These two brands have low RPMs that fall within the category of 3,500 and 3,800.

Moreover, they come with additional accessories that enhance their durability, compactness and general user experience.

The use of specialized handles ensures that one can comfortably maintain grip and control over long hours.
If you are looking for an advanced cordless circular saw for heavy-duty work, then the PORTER-CABLE 20V Max 6-1/2-Inch, the DEWALT 6-1/2-Inch 20V Max Circular saw or the Makita SSH032 18VLXT.
