It’s yet another day that we bring you an awesome topic in the life of a woodworker – corded vs cordless circular saw. What is the best choice to go with? Well, you’ll have to stick around for a while to make the right choice.
For over eight years that I have been a woodworker, I have been asked this question over and over again. Yes, it might look simple but trust me it isn’t. For any woodworker to make the right choice (especially a beginner), they’ll have to learn the pros and cons of every one of these circular saws.
Luckily for you, you don’t have to go through all this tussle. In this post, I will show you everything that you need to know about corded or cordless circular saw which will help you to pick the most relevant tool for your use.
Take a look at what I have laid down for you.
Cordless Circular Saw Vs Corded: The General View
Generally speaking both these saws are circular saws. As such, they are an excellent tool for any woodworker or carpenter. Both are tools that most woodworkers have used for many decades to complete some of the most complex cuts and designs on wood.
They are best for cutting, shaping, and tearing through lumber. Basically, they are also the two main types under which the circular saw is categorized and each performs exceptionally well in their respective uses.
So which uses are these? Don’t you worry, by the end of this post, you will have a clear picture of which circular saw among the two is best for which use.
Corded Vs Cordless Circular Saw: An In-Depth Look
To get a clear picture of what we are going to deal with, we have to divide these circular saws in corded and cordless saw.
Corded Circular Saw
The corded circular saw like you may have guessed is operates with a cord. It has a cord that’s attached to it which you will plug into the power source before the saw is turned on. Once connected to this electrical power source, the cord supplies the power to the saw’s in built motor.
The motor then triggers motion and runs the circular saw blade. Once the circular saw is triggered, it moves at high speed and in the process cuts through a number of things including wooden workpieces to thin metallic sheets.
The corded circular saw is often liked by many users due to its sheer power, strong metallic alloy build, high efficiency in finishing heavy loads of work, and above all that its friendly operation or ease of use.
Even better, they also have large round carbide blades that makes cutting through heavy lumber an easy job.
With speeds of close to 3500 RPM, this saw offers one of the best guarantee when looking for a sawing model that’ll guarantee smooth operation at any given time.
Cordless Circular Saw
Unlike the corded circular saw that we have just talked about, the cordless circular saw is a great saw for the modern workshop too. More importantly, it is the best option if you are going to work off the grid.
The saw uses a rechargeable Lithium Ion Battery which makes it the best saw for homes with no power, renovations off the power grid, and job sites that have many floors and limited power supply outlets.
According to many people who have worked with this saw, myself included, there is a general feeling that since this saw has no cord (which would have tied it to a specific power outlet) it the super option if you are working in congested or widely open area.
Cordless Vs Corded Circular Saw: Similarities and Differences
Now let us take a look at how the corded vs cordless reciprocating saw compare. Take a look at what we have.
When comparing the two saws, they both use the same type of sawing blade (a circular saw). This means that their mode of operation is the same. Both will cut through wood using a circular saw movement. The movement of the saw is triggered by the presence of an inbuilt motor technology.
In addition to the above, all these saws can serve on the same type of operations. They will be used to cut through wood, lumber, thin metallic sheets, and sometimes concrete. Well, the operation timeline might differ, but even so, the operation technology remains similar.
Next, both their blades are replaceable. The blades can both blunt or become dull. As such, they must both be replaced or sharpened to maintain higher efficiency.
Apart from the similarities, there are some acute differences between the corded and cordless saws that are so prominent.
Corded circular saws operate using direct electrical power. This means that you must get a jobsite with a plug in spot such as an electrical outlet to use the saw. You can also use a generator supported electrical system.
However, the cordless circular saw on the other side uses the rechargeable lithium ion battery as its main power source. The only down turn to that is this. You cannot have a continuous cutting experience since once the power is low the battery has to be recharged before you resume.
Even so, with a battery backup, you should be able to run for longer. Because of this types of runtime, the cordless circular saw can often be used with jobs that require limited runtime.
Because the corded circular power saws operate suing direct electricity, they can easily maintain the same high-end power. This provides them with high strength when cutting through any type of material. Thanks to the constant power generation that you will get throughout your runtime.
This however, cannot be said of the cordless circular saw. Unlike the corded, the strength of the lithium ion battery will wear out as you use it. Eventually, after it falls below 20% it might not be able to run the sawing blade.
As such the strength of the cordless circular saw is not quite reliable especially for a job that goes beyond their battery use timeline.
Looking at the same point on strength, and borrowing the same principle when looking at the speed of a circular saw, one thing is clear when you compare the cordless circular saw vs corded.
As the power in the lithium ion battery wears out, the blade speed also goes down. The revolutions per minute (RPM) will fall. This will leave you with a slower blade unlike when the battery was at 100% full power.
Corded saws on the other hand don’t experience any power relapse since the electrical power supply is often constant. As such, their speed is always constant from start to finish of the works.
Corded circular saws because of their constant power often come with larger blade sizes. The blade sizes are carbide blades of about 7 inches. This is unlike the cordless circular saws that will reduce on the size of the blade or improve on the battery capacity to maintain the same results.
With all other factors remaining constant, corded circular blades will make the best tool for heavy DIY projects.
Larger blades have larger reach compared to smaller blades. A 7 inch carbide blade will have a further reach than a 6 inch carbide blade. While most corded circular saws will also have this benefit, cordless saws may be forced to reduce in their blade size (blade reach) to measure up to the same capacity as their corded counterparts.
Another best advantage when you compare the corded vs cordless circular saw is the need for accessories. While the corded models will require only blade replacements, their cordless counterparts might need both blade and battery replacement.
In short, the price of the cordless models could easily shoot. However, this might not be so true as the parts that the corded models use also come at a price. Remember, better efficiency might come at an extra price too.
Looking at the cordless circular saw vs corded circular saw with cord, one thing is clear. The cordless models will offer better overall reach. While their corded sisters are limited by the length of the cord, you can always carry your cordless circular to whatever lengths you need – no restriction and no hassle at all.
While the corded circular saws will operate continuously without ant forms of stops, their non-stop operation is only possible where there is continuous power supply. In case of a power outage, they cannot work. The same cannot be said of the cordless models as they have an inbuilt power bank.
Size of Teeth
Unlike the corded models, when looking at the circular saw teeth between the corded vs cordless tools, you will realize that the cordless models come with very small teeth. The teeth is safe for general operation and will not have a high chance of injury such as that of the corded models that have large teeth.
Which Model Should You Use?
Depending on your needs, here is what you must know. Corded circular saws are best for continuous cuts on limited spaces. On the other hand, the cordless models are best for unlimited reach and on areas that are situated off the power grid.
When looking at cordless vs corded circular saw, chances are you will get different models for different pricing. Once you have a budget, your choice should be based upon, the type of work that you need and how fast you need to complete the job.
Again you must also look at the job in question. If you need something to use within your workshop, a corded model will be advisable.
After reading a clear brief, I hope now you’re capable of choosing the best circular saw for yourself. And also, you understand clearly the difference between cordless vs corded circular saw.
