9 Best Cordless Circular Saws [2019 Complete Guide]

Best Cordless Circular Saw

A circular saw is characterized by a round, toothed blade that cuts via rotary motion while turning around an arbor, and is held above the cutting surface by a metal plate (shoe).

Traditional corded circular saws are quite powerful, but their cabled design limits their reach and use because there must be a power outlet nearby.

However, cordless circular saws are battery-powered, making them easily portable because they can be used almost anywhere. That said, if you want one, these are the best cordless circular saws to consider buying.

Corded vs. Cordless Circular Saw

Corded vs. Cordless Circular Saw

The most obvious difference between these two is that corded circular saws must be connected to a power outlet while cordless units pack in their own power supply in the form of batteries. There are other differences that arise from this powering mechanism and these are:

1. Cutting Power

Corded circular saws have the benefit of having an unlimited power source and therefore, they are usually more powerful, with high torque motors that cut through wood and other materials with ease. They are ideal for very intensive cutting jobs.

On the other hand, the major limitation of cordless circular saws is that their power supply is limited. Therefore, their cutting power is also limited and more so as the battery charge level drops. They are ideal for jobs that are not very intensive.

2. Cost

Corded units are usually cheaper than their cordless counterparts, primarily because they don’t require batteries and chargers. In most cases, cordless units are sold as tools only, which means you have to spend extra to get these must-have accessories.

3. Portability

This is where cordless circular saws excel. Battery power allows them to be easily portable, thereby giving you the flexibility to move around your worksite or to a different site quite easily.

4. Size

Due to the battery, most cordless circular saws are larger and heavier than their corded counterparts. The larger the battery that you fit in, the heavier that it will be. This makes the cordless units a bit difficult to handle in comparison to the corded type.   

How to Buy the Best Cordless Circular Saw

How to Buy the Best Cordless Circular Saw

1. Battery Power

A powerful battery will definitely deliver more power to the saw, leading to a longer runtime. That said, you need to check the voltage and amperage, in which the higher these values are, the better.

However, regarding the voltage, ensure that the battery’s voltage is compatible with the saw’s internal electrical system, which is usually either 18 or 20 volts.

2. Blades

Carbide-tipped blades are very popular because they are very durable and maintain sharp tips for a very long time. However, they are quite expensive.

If you are a bit tight on cash, high-speed steel blades are a bit cheaper than their carbide-tipped counterparts and are ideal for high volume cutting work. Therefore, a saw with such a blade would be very handy if you have lots of pieces to split.  

Other than that, there are blades for different types of materials other than wood. For instance, if you want to use the saw for tile cutting, ensure you have tile cutting blades fitted in.

3. No-Load Speed

This basically means the spinning speed of the blade when not cutting. Measured in RPM, this speed will drop as you slide the blade into your workpiece because the cutting process acts like a brake.

To avoid slow cutting speeds, ensure the saw you buy has a high speed, high torque motor so that, even when cutting, the spinning does not drop that much.

Ideally, 3,000-5,000 RPM is good enough but any RPM past the 5,000 mark is best. Anything below 3,000 RPM will cut at very slow speeds.

4. Bevel Capacity

Bevel cuts are ideal for decorative trims and are achieved by tilting the footplate on the angled plate. Each circular saw has its own bevel range but the ones with wider ranges are better because they are able to create a wide variety of different cuts.

Another thing to check is if there are special stops on the bevel scale, which should be positioned at common angles for convenience and easy use.

5. Cutting Capacity

A saw’s cutting capacity is very important to consider because it determines its cutting abilities. This capacity basically means the depth or thickness that the blade can reach. Therefore, if you want to cut very thick pieces of wood, make sure to check if the saw is up to the task.

6. Safety Features

Safety features are important for protecting both you and the tool from damages. The most important ones to have include:

Electronic brakes

In normal instances, blades continue spinning for some time after releasing the trigger. This makes it a bit risky because the sharp edges might cut your fingers or damage anything that comes into contact.

Electronic brakes help to prevent this by stopping the blade as quickly as possible once the trigger is released.

Blade guard and Shoe

These two components help to protect the blade and other internal parts from damages in case of drops or bumps. Other than that, the blade guard keeps the blade covered so as to prevent accidental cuts to your fingers even when not spinning.

Overload, overheat and over-discharge protection

These 3 always go together and are meant to protect and preserve the battery for long-lasting performance.

As a general rule of thumb, the more the safety features, the better.

7. Weight

Handling a heavy circular saw can cause hand fatigue very easily because lifting it and setting it to different workpieces can be quite tiring.

That said, any weight below 7 pounds is comfortable to lift but on exceeding this, you should have enough physical strength to carry that weight with ease.

Conclusion 

To conclude, cordless circular saws are very important additions to your toolset and as you can see above, these pieces have slightly different features, but all are designed to give you that perfect cut.

That said, using our buying guide, you should be able to pick the best cordless circular saw that suits your needs from the ones in the review.
