How Many Watts Does A Circular Saw Use?

Circular saws are one of the most popular tools for DIY homeowners. But how many watts does a circular saw use? And is that something you need to worry about when choosing a saw? In this article, we’ll explore the wattage of circular saws and find out if it’s something you need to consider when making your purchase. We’ll also look at some of the best circular saws available on the market today, so you can be sure you’re getting the most bang for your buck. 

How much power does a circular saw use? 

Contrary to popular belief, it’s not all about the speed of a circular saw. Yes, having more RPMs means that the blade is spinning faster and will cut through wood faster than slower-running blades. However, you also need to look at the amps (A) that the circular saw uses. If you’re wondering, “How much power does a circular saw use?”, it’s all about the amps. A circular saw with higher Amps is going to use more electricity than one with low or medium Amps. 

What is AMPS? 

If you think of watts as lightbulbs and amps as the electricity that makes them work, you’re not far off. Watts and amps are related to each other and use one to describe the other: 1 amp is equal to 12 volts (V) running at a constant rate of 120 hertz (Hz). That means every time your power source emits 1 volt, it’s pushing 120 electrons through it. 

Watts vs. AMPS: How do I choose the best saw? 

By choosing a circular saw with higher amps, you’ll get more power, but it will cost you battery life. Of course, what you value more is up to you (and your wallet). You can’t go wrong with either high or low amps, but it’s always good to know the whys and hows before making a purchase. 

How to choose the right circular saw for your needs? 

When choosing the best circular saw, you should consider its power source. Cordless circular saws are most often powered by 18V lithium-ion batteries (Li-ion), which give you great (and loud!) portability, but they might hinder productivity if they die out before completing your project. Circular saws that plug into the wall are just as powerful, but they’re restricted by a cord and require an electrical outlet. Corded circular saws have the highest power density, but they’re also restricted by their length of cord.

Cordless vs. corded 

If you’re not sure if you want to go with a cordless or corded circular saw, think about where you’ll most often be using your saw. If it’s mostly in one place, a corded circular saw is probably the best choice for you. You can just set up an extension cord or move around with a long enough power source that plugs into the wall. 

If you’re mostly starting projects in different locations, a cordless circular saw is a great option for you. Cordless circular saws are still powered by electricity, but they have a battery pack attached so that they can be easily moved from location to location without being restricted by a cord.

A circular saw uses electricity and if you’re using a power tool, it is important to know how many watts are being used. This can be done by looking at the voltage of your tools or checking for an indication of the product. The more amps in use mean that there will be more current flowing through your circuit which could mean something bad for your device so take care!
