Circular saws with a battery allow you to cut boards, beams, sheets of plywood and other building materials remotely from a 220 V power source. It’s also convenient because it doesn’t have a hanging power cord, which makes it easy to use at height, like when trimming a fronton, for example. Our experts have figured out how to choose a cordless circular saw and which models are considered the best among users. This review will help even a beginner to quickly dive into the topic and decide on the right product for you.
How to choose a cordless circular saw
When choosing a saw it is important to be aware of its key characteristics. Here are the 9 main parameters to look out for.
Voltage
In the case of a hand saw with battery, the operating voltage of the latter is equivalent to the power of the mains tool:
- 10.8-12 V are considered domestic and are suitable for occasional board trimming or garage work.
- The most common variant are saws for 18 V, which are optimal for work on the roof, professional fence installation, etc. d.
- Voltage 36-54 V is available only for the most powerful units, designed for work with increased loads (for example, for operation for 8-12 hours a day or for cutting of solid wood).
The more powerful the device, the less it will be warm to operate, and its speed will not drop from the pressure of the operator.
Charging time and capacity
Since the saw is battery powered, the battery capacity is important for the autonomy duration:
- Indicator 2.0 A / h is enough for household use, to saw the fence or branches in the garden.
- 3.0-4.0 A/h are suitable for occasional use during roof repairs and other short-term processes.
- Professional saws have batteries with a capacity from 5.0Ah, which provide long-lasting autonomous operation.
In addition to the capacity, the speed of charging is also important, so that with two batteries you can alternate their use and work continuously. The fastest battery charging speed 5.0 A/h is 100 minutes. As long as one battery is being used in the saw, the second battery can be charged. Charging a similar capacity in 180 minutes is considered to be a low benchmark.
Rotation speed and speed control
Speed of cutting depends on the number of revolutions. There are values from 1500 to 6000 rpm. The higher the number, the more powerful the saw is. The ability to adjust the rotation speed allows you to set the right indicator for cutting materials of different density, so as not to burn the ends of wood (if you saw pine at 6000 rpm, there is a black mark – the wood burns).
Engine type
Saws with brush motors cost less, but last less and periodically need to replace the graphite consumables. Brushless circulators have three times the life, but cost more.
Disc diameter and maximum cutting capacity
Depending on the size of the tool, the cutting depth performance depends on. Gear wheels of circular saws are available with diameter from 85 to 190 mm. Accordingly, cutting performance is also possible from 2.5 to 6.1 cm at 90º and 1.6-4.1 cm at 45º slant. If you often have to work with planks 40-50 mm thick, it is better to get a circular saw with a 165 mm blade or more.
Diameter
The handheld circular saw accessory is put on a shaft with 15, 20 or 30 mm seat size. This determines what consumables you will be able to attach in the future (their cost and availability).
Weight
The weight of the handheld circular saw plays an important role when working with a circular saw for long periods of time and affects fatigue. The lightest models have a weight of 1.6-2.5 kg, the medium ones weigh about 3.5-3.9 kg, heavier up to 6 kg.
Features
Having a variety of features increases the convenience of the circular saw and expands its capabilities:
- Backlight makes it possible to make precise cuts in dark places without the need for additional lighting.
- Laser pointer helps to keep the saw precisely on the marked line.
- Motor brake stops spinning faster after the trigger is released, increasing safety.
- Keyless blade change for easy and time-saving tool changes.
- Soft start avoids jerky starting and allows precise positioning of cutting element to the entry point.
Outfitting
Together with a saw, the manufacturer can supply additional devices that give everything you need to start working. Among them are: 1 or 2 batteries, battery charger, parallel stop, carrying case, adapter to the vacuum cleaner, keys. But there are also products without battery and charging station, sold in a box. This is relevant if you already have a battery of such a company, corresponding to the voltage, as well as your own roomy tool case.

The Japanese manufacturer manufactures a cordless one-handed saw that operates on a 12 V battery with a capacity of 4.0 Ah. The torque is created by a brush motor, and the maximum RPM is 1,500 per minute. As a cutting element is used a disk with a diameter of 85 mm, which allows you to cut at right angles to a depth of 2.5 cm, and under the bevel 1.6 cm. Comes in a rugged case that also fits the carrying. To change the tooling, you will need an Allen wrench, fixed to the body next to the motor. It helps not to lose inventory and is easy to change wheels. Users in the reviews are pleased with the quality of the disc from the kit and the presence of two batteries at once, although the cost of the saw is much lower than analogues.
