When you buy a circular saw, you can find two types called corded and cordless circular saws in the market. According to your requirements, you should select the desired tool that you need. So let’s see, is it worth buying a cordless circular saw by considering the cost, spare parts, service, troubleshooting, and many more.
It is really worth buying a cordless circular saw by spending 60$-150$. Because it can be used without a power cord and power supply, that will be easy to use outdoor and portable. Cordless saws are powered by Li-Ion batteries, and they can use about 30 mins continuously.
More than that there are both pros and cons I could see when I used this. So I would like to mention all in detail about the cordless circular saws. So let’s see whether it is compatible with you.
Main Differences Between Cordless and Corded Circular Saw
We can see both corded and cordless circular saws in the market. Among them, we should know what are the main differences.
The main difference is the power supply. Corded circular saws have a power cord to connect the power supply. But cordless circular saws do not have a power cord. There is a Li-Ion rechargeable battery to power up the tool. Using this you can use it until it is dead.
When the current is high, its torque can increase. There are 10 Amps and 15 Amps in the corded saws. But cordless saws have various currents. Because it is powered by a battery. When the circular saw current is reduced, it can be binding with the cutting surface. When the battery is discharging while it is using, you can face this.
Corded circular saws are weightier than cordless circular saws. Most corded circular saws are with 7.25 inches saw blades. It is more weight because there is more winding inside it.
Cordless saws are not weighed much, although there is a battery. It has been designed as it can be handled using a single hand.
Cordless circular saw blades are mostly 6 1/5″ and corded circular saw blades are with 7 1/4″
Cordless circular saws have 2 1/16″ of cutting capacity, and a corded circular saw blades have 3″ cutting capacity.
How Much Will it Cost for a Cordless Circular Saw?
Usually, 6.5 inches circular saw will be 60$-120$ and 7.25 inches circular saw will be 100$-150$. This price will be varied with the manufacturer’s brand, saw blade size, battery, and voltage capacity.
When you buy a circular, saw you should know how much will it cost for power, services and parts.
There are mini circular saws with smaller saw blade sizes. These can be used for thin workpieces. When you buy cordless circular saws, you should know whether the battery and charger are included in that price. Most of the time, we do not provide the battery can charger. We have to buy them separately. So you will cost an additional price for the battery and charger.
According to the voltage and capacity of the battery, its price can be varied. We can buy 18V, 20V, 36V, and 56 volts batteries with 1.5 Amh. 2 Amh, 3 Amh, and 5 Amh batteries. When the capacity is high its price will be high. Sometimes we can see rapid chargers also. Normally a charing time will be 45 mins to 5 hours. So using rapid chargers, you can charge a battery below 30 mins. So it is better to invest in these things.
And it is important to know you can’t work the whole day using a single battery. You should have 2-3 batteries with you. If you continue working with a single battery, it will be sufficient for 30 mins. So you should need to recharge it. I can recommend you to have 2-3 batteries with you. So you can use them by interchanging.
Power Requirements of the Cordless Circular Saw
A cordless circular saw consumes less than 200W of power while it is used. Corded tools need a power supply and power cord to connect with the power supply. So you should have a proper standard wire cord when you use this.
But, if you use the cordless tool, you can use a rechargeable battery. Rechargeable batteries are with different voltages and capacities. Cordless saws have an optimized power consumption due to limited battery capacity.
There are both Li-Ion and Ni-Cd batteries are available in the market. I recommend you to buy a Li-Ion. It is less maintenance and safe. But Ni-Cd is not safe. When you use a long time you can see some charging problems there.
It is really worth having a cordless circular saw when considering its power requirements. Sometimes we are not able to provide a power supply to the worksite. At this time cordless tool is a very important one.
Considering safety it is safer than a corded one because there is no warning for the damaged cable and electric shocks. And also we no need to manage power cables. We can use it in any position easily.
Cordless Circular Saw Usage and Performance
A cordless circular has good performance. But it is not higher than the corded tool due to the battery, there is a limited time performance. When the battery is discharging, its performance can reduce. The tool is powered by brushes or brushless motors. Using a brushless motor will remain more battery capacity. Because it is more efficient than brushed motors.
The only disadvantage is not able to use a long time. It is not a worth factor.
Spare Parts and Maintenance of the Cordless Circular Saws
If you use a corded tool or cordless circular saw, you should service and maintenance it. Because brushes can be worn, saw blades can be dirty and dull, sawdust problems, and many more.
Additionally, we have to charge the battery. Normally a Li-Ion battery can be used for about 3-4 years. If it charges and uses it properly. One of my friends used a battery for about seven years. So you have to spend additional costs on the battery and charger.
If you use a corded circular saw, you have to spend money for the power cord.
Other maintenance and services are the same cost. It depends on the way we use it.
