The ability to fabricate and construct has been one of the most important abilities of man, since the beginning of time. Our ability to innovate has enabled us to come up with complex structures built in a series of intricate steps; all to improve our lives.
Very important to fabrication and crafting is the cutting process. For millennia, cutting technologies remained primitive and very inefficient, requiring much muscle effort until the invention of the circular saw between the late 1700s and the early 1800s. The idea of the portable circular, however, is accredited to Art Emmons in 1929.
Thanks to rapid technological advancements in fabrication and the dawn of powered motors, modern circular saws are now much lighter, more powerful, and far more efficient; making the cutting process just another light task to do.
As a professional craftsman or DIY hobbyist, choosing the right circular saw to add to your toolbox is not so straightforward. As there are just so many brands out there, you can get lost in the myriad of adverts.
So how do you pick the right saw that will be reliable and provide real value for your money? Well, worry not.

Circular Saw – Buyer’s Guide
What are circular saws?
If you are big on woodworking or cutting in general, then you should know there are several power tools out there designed to cater to your cutting needs. However, few of these tools come close to the circular saw in terms of all-round performance.
A circular saw is a powerful cutting tool designed to split different materials such as wood, metal, concrete, plastic, and glass with a high degree of precision and accuracy. Since they made their first appearance on the cutting scene, circular saws have proven to be quite reliable machines capable of handling almost anything thrown at them.
Parts and Features of a circular saw
Before choosing a circular saw to buy, you must gain some degree of familiarity with its essential components and features. A typical chainsaw comprises:
This part of a circular saw is used to adjust how deep your blade will cut. Most times, the depth adjustment can be found at the back of the saw. Depth adjustments also have indicators that tell the user how deep a cut is going to be.
Most circular saw models employ a cutting depth of 2.5 inches.
Circular saws are suitable for making bevel cuts, and they usually include an adjustment feature that enables you to set the blade angle within a range of 0 to 45 degrees. Most times, you can locate this feature at the front of your saw, towards the side.
The plate is a thin strip of metal that runs around the cutting saw and provides a base for it to sit on the workpiece while cutting. Saw plates are typically made of metals such as steel, aluminum, or in some cases, durable thermoset plastic.
A circular saw’s plate helps keep your hands steady while cutting, and also serves as a form of a guide when moving the saw along a workpiece.
The blade cover is a strip of metal which fits entirely over and under the cutting blade. This cover serves to protect users from accidental contact with the blade while cutting. And it is typically designed with an opening in front, which ensures the cutting process is not impeded.
Also, check the saw to ensure there is a bit of gap between the blade cover and the blade itself, so it doesn’t get caught repeatedly in the blade while in use. The cover also acts as a sort of dirt collector by preventing debris from flying around while working.
Blade lock mechanism
Just like its name, the blade lock mechanism is a simple feature that enables users to fix their blade in place while installing or removing one. It also helps you keep the saw blade steady while cutting is in progress.
Most circular saws come with this blade lock feature, but if they don’t, then you’ll have to do all the hard work yourself and stop the blade from spinning while trying to loosen it.
I think we all know what a handle is and the function it serves on any piece of equipment. Circular saw handles provide a surface for users to grip and maneuver their tools while working. Some circular saws come with two handles, which enable you to operate the device with both hands, consequently providing a firmer grip and better stability while working.
Most circular saws these days feature an ergonomic handle design, which makes handling the tool a user-friendly experience.
This one is self-explanatory. If a circular saw works with electricity, there usually is a cable that you connect to a power outlet whenever you want to work. Most times, this cable is detachable; thereby, making storage of the saw quite easy.
The work of a bolt clamp is quite simple, but it is of utmost importance. The bolt clamp is used to fasten the blade to the saw securely. This ensures the blade doesn’t fall off while cutting and guarantees a higher degree of user safety.
Power and trigger switch
The power switch turns the saw on or off, while the trigger simply controls the saw blade. A trigger proves quite useful when you turn on the saw, but for one reason or the other, you are not ready to work.
How does a circular saw work?
After familiarising yourself with the parts of a circular saw, let’s get down to how these parts work in tandem to create cuts in materials.
For corded circular saws, the first thing you need to do is plug your equipment into a dedicated power outlet. Cordless saws do not require a power cord, and most designs feature a simple start button that you push to get the tool working.
However, before you begin cutting at all, you need to set the depth at which you’d like to cut using the depth adjustments. Also, if you’d like to make bevel cuts, now would be a great time to adjust the saw’s cut angle. For a smoother cutting experience, mark your workpiece so you’ll have guidelines for your blade to follow while cutting. This ensures greater accuracy while cutting.
Once you connect the saw to a power source or you engage the start button, the saw blades begin spinning in a clockwise direction with great force. This rotary action enables the edge to cut through the material while generating a lot of debris at the same time. Keep moving the saw in a forward direction until your cut is complete. Once you’re done cutting, switch off the trigger and wait for the blade to stop moving before you remove the saw.
Who needs a circular saw?
A circular saw is a piece of versatile equipment used in a vast range of cutting operations. It can comfortably cut materials across the wood grain, along the wood grain, and is equally adept at making plunge cuts from above. What’s more, circular saws can be used to make cuts in several other materials including plastics, metals, concrete, etc.
Even better, circular saws have bevel adjustments that enable users to make bevel cuts at angles ranging from 0 to 45 degrees.
Circular saws are also generally portable, and you won’t have an issue moving one from place to place – you can even climb up to your rooftop with it!
If you are operating on a tight budget, you might want to consider buying a circular saw, as they cost relatively less compared to other cutting equipment out there.
Cordless vs. corded circular saws
The decision on whether a cordless or corded saw is the best for users will remain an age long debate, but the final choice rests ultimately on your taste and preferences.
Corded circular saws are those that require a power cable connected to a dedicated power outlet to work. The range within which you can work with these saws is limited to the length of the power cords. And most times, you will need to work close to a power source. As a result, corded circular saws are not fit for use out in the field, and are suited better for workbench usage.
That said, corded circular saws are more powerful than their cordless counterparts, and are suitable for heavy-duty cutting.
Cordless circular saws, on the other hand, do not require an external power outlet, and they work with a battery. The absence of power cords means a broader range of use; hence, they are useful for field cutting. Also, cordless circular saws tend to be lighter in weight than those with cords as a result of the absence of motor engines. Consequently, saws without cables are easier to work with, and users can go on cutting materials for long stretches without feeling fatigued.
Although cordless saws are generally less potent than their corded brothers, they are no slouchers either and will carry out most tasks comfortably. A significant downside of using them, however, is that you’ll have to pause your work at regular intervals to recharge the battery.
As stated earlier, your choice of either a corded or cordless circular saw boils down to personal preferences. If you like a saw that will allow you to carry out basic cutting operations with no movement restrictions, go for a cordless saw. However, if you are a professional who needs higher cut power, greater cut depths, and overall superb build quality, a corded saw is your best bet.
Blade left vs. blade right
Circular saw blades can either be left-sided or right-sided, depending on the side of the blade cover that is exposed to reveal the edge.
For blade left saws, the saw blade is exposed on the left side of the equipment. As a result of the positioning, blade left saws are more suitable for use by right-handed people. Not only will you find it easier to maneuver a blade left saw as a right-handed person, but you will also be able to know what you are cutting.
However, if you, as a right-handed fellow, decide to work with a blade right saw, be prepared for a more stressful cutting experience. You are more prone to getting hit by the debris that flies away while you cut, and there’s a higher injury risk attached. You will also most likely have to handle the saw with your left hand, and this is nothing but a recipe for discomfort and haphazard cutting.
The above scenario applies to a left-handed individual operating a blade left saw.
However, the first set of circular saws were all blade right, and both lefties and righties used them successfully without complications. The whole issue of blade left, and right blade saws boil down to the comfort of the user, and you should go for whichever one you find more natural to use.
Circular saws blade size
The size of your circular saw blade ties in directly to the amount of satisfaction you are going to derive using the saw. Typically, saw blades come in two primary forms: rip and crosscut blades. Rip blades cut materials along the grain of the wood while crosscut cut across the grain of the workpiece.
However, when it comes to blade size in terms of diameter, you have four standard options to choose from. Blade sizes that dominate the market are the 4.5, 5, 7.25, and 10-inch blades.
The 4.5-inch blades are dwindling in popularity these days, but they are still quite capable of handling basic cutting tasks.
Most of the circular saws you’ll find in the market today come fitted with a standard 5-inch blade. The versatility of these 5-inches makes them a good fit for both cheap power saws, as well as high-end equipment. However, in most cases, 5-inch blades do not have more than 24 cutting teeth; hence, they are more suited to cutting thick materials.
As common as the 5-inch blade saws, if not more popular, are the 7.25-inch saws. Full-sized circular saws come equipped with a 7.25-inch blade, and they are widely employed in woodworking. 7.25” blades have a high cutting depth and will comfortably cut through plywood that is between 2/3 to 8 inches thick. 7.25-inch blades that have a lot of teeth can as well be used to cut through tile and aluminum – provided the cutting edges are coated with diamond.
10-inch blades are not as universal as the other blade sizes, but they can handle a wide variety of cutting projects reasonably well. This blade size is particularly suited to heavy-duty projects and is also able to cut through unique materials such as ceramics.
When choosing a saw to buy, have it at the back of your mind that 7.25-inch blades are generally cheaper than other blade sizes, and you will find it more convenient cutting with them. Also, when making bevel cuts, larger blades allow you to make deeper cuts at angles in one cutting motion. With small blades, you are likely going to make several cuts before you get the desired shape.
How to use a circular saw without a table?
When working in a workshop, the ideal equipment for firmly securing your workpiece to ensure accuracy and precision is a work table. However, there may be situations where you just have to work without a table. In times like this, the next best thing you can do to secure the workpiece is to make use of a suitable clamp. This will help press the work material down and ensure stability while cutting, leading to more accurate cuts.
Whatever you do, do not attempt to hold down a workpiece with your hand while operating a circular saw. Not only is this highly dangerous, but you might also end up losing your hand if things go south.
Features that matter when choosing a circular saw
Apart from the main parts of a circular saw, there are several features you should look out for when choosing a circular saw to buy. These features enhance your overall cutting experience and are most times, the difference between an average saw, and a world-class cutting machine.
Some of these qualities that will elevate the performance of your saw include:
When choosing a circular saw to buy, you must go for one which has extra features to improve the precision of cuts in place. Some of these desirable qualities include the presence of accurate cutline markers, seamless blade cover retraction as well as plates set entirely parallel to the cutting blade.
Once you are done cutting, and you turn off the circular saw, you have to wait a couple of seconds for the blade to stop rolling before setting the equipment down. This wait is essential as you might get involved in a freak accident and injure yourself severely even after switching off the saw. However, if you are in a hurry to do something else, waiting for the blade to stop moving can prove to be very time-wasting. Hence, the introduction of electric brakes.
Electric brakes work by reversing the flow of electrical current in the saw’s motor to slow down the spinning rate of the blade after the saw is turned off. These brakes are capable of stopping a blade in as little as two seconds, compared to the average twenty seconds obtainable when you just let the blade roll on its own.
This here is a feature for the amateur cutters. Laser guides are small LED flashlights on the saw that, once engaged, provide a form of direction that enables users to make accurate cuts with the saw – think of it as the electronic form of the carpenter’s pencil. My major grouse with laser guides is the fact that they are often inaccurate. Also, once I get deeply engrossed in my work, I tend to pay more attention to the saw’s plate for accuracy rather than depend on the laser guide.
The LED light provides a source of illumination when working indoors or in dimly lit areas. The LED light is typically a small flashlight bulb that comes on when the saw’s trigger is engaged, even if you’re working in broad daylight. Some circular saws, however, feature a dedicated switch with which you can control when the LED light comes on.
Another feature that can considerably make the cutting process a whole lot easier for you is the type of grip on the handle of the circular saw. Handles covered with a soft rubber material will be much more comfortable for you to hold and maneuver. High-end circular saw models feature ergonomic designs that make handles more comfortable to hold while sawing and better overall stability.
As insignificant as it might sound, where the trigger is placed on your circular saw and the ease with which your thumb reaches it has a telling effect on your cutting experience. It can prove to be quite awkward, having to constantly reposition your hands each time you want to lessen the cutting speed. And moving your hands anyhow while the saw is running is not a good idea at all.
Therefore, when shopping for a circular saw, pay extra attention to the ease with which you can comfortably press the trigger switch while working.
Yes, circular saws have a blade cover designed to keep particles from flying around while working, but it would be of added advantage for you to buy a saw with an extra dust blower feature. The dust blower clears particles that tend to gather on the workpiece, making it easier for you to see what you’re cutting.
Another thing you need to take into consideration when buying a circular saw is the design of the saw’s shoe. Most modern circular saws leave a considerable amount of space in the middle of the shoe to create a little bearing surface, which keeps the saw steady while in use.
Irregularities in plate flatness can cause it to tilt and shake while cutting, leading to inaccurate lines and shapes. Also, the edges of the shoe must be set parallel to the blade so it can serve as a form of cutting guide while in use.
Sidewinder circular saws vs. worm drive circular saws
Circular saws are classified into two main groups based on the position of the motor on the body of the saw. According to this grouping, circular saws can either be Side Winders or Worm Drives.
A sidewinder circular saw (also known as an in-line saw) has its motor mounted at the side of the saw, giving it a more compact design. Sidewinders are the most common types of circular saws out there, with six out of every ten saws you encounter likely to feature that design. Worm drive circular saws, on the other hand, have their engines located towards the back of the saw.
Sidewinders are more comfortable to use because the motor rests on the workpiece while in use, boosting stability. Most sidewinders are cordless, and they require little or no maintenance. They also weigh less than other types of saws; hence, you can comfortably cut tree branches with them.
Worm drive saws are the bad boys built to handle the big cutting projects. The saw’s cutting power translates to the blade via two gears placed at angle 90, consequently providing a better rotational effect. However, you have to carry out regular maintenance on worm drives, and this includes changing out the oil now and then.
Popular circular saw brands
A circular saw market is a vast place, and there are tons of products from which you can make a choice. As a first time saw owner, it might get confusing having to sift through endless saw choices, and you might end up picking inferior equipment.
For better quality assurance, there are several brands you should consider ahead of others when choosing a circular saw to buy. These brands have proven to be reliable manufacturers over the years, and you are guaranteed a certain degree of effectiveness and efficiency while using their products.
That said, some of the brands that produce the best circular saws on the market include:
If you’re big on power tools and equipment, chances are you’ve, at one point or another, used a DeWalt product. The DeWalt brand is one of the most famous names in the manufacturing industry, with a wide range of professionals using their products in various capacities.
DeWalt circular saws possess lots of innovative features, and they cater to a wide range of users, from the professional cutters to the complete greenhorns.
Another dominant name on the circular saw scene is the Japan-based power tool company, Makita. Makita specializes in creating different kinds of saws, and their products are renowned for their versatility and affordability.
Porter-cable saws are massive favorites among professionals, and this is all for a good reason. Apart from their strong links with industry giants, DeWalt, Porter-cable produces high-quality circular saws that are user-friendly and continuously deliver excellent work.
The company can also boast of inventing the most widely used circular saw design in use today – a lightweight helical-drive circular saw introduced in 1929.
Ryobi is yet another prominent Japanese saw manufacturing company, and they have been around for the past fifty-two years. The company produces affordable saws designed for less professional work, but impressively, their products manage to deliver excellent work.
Circular saw maintenance tips
To get the most of your circular saws, there are practices you need to carry out frequently. Circular saws are quite easy to maintain; with the bulk of maintenance practices, you will carry out focused on the blades.
Things you need should do to keep your saw in top shape and continue making perfect cuts include:
- Regular disassembling and cleaning of the machine to remove bits of debris that might clog up the engine, or impede blade movement.
- Wipe the saw blade clean immediately after use and spread it out to dry.
- Regularly take out and replace lubricating oil for saws that need it.
- Cover up your saw when not in use, while paying particular attention to the blade. Leaving the saw exposed to air leads to rusting of the metallic parts.
Safety tips to follow when using circular saws
Circular saws, like every other power tool, are quite useful, but they can also prove to be equally dangerous if not handled properly. There are some safe habits you should adopt to ensure you are always on the safe side whenever you are operating a circular saw.
Some of these safe practices include:
This is one precautionary measure that I cannot stress enough. The majority of the machine-related accidents that happen would have been prevented if only the operators dressed adequately.
Before you begin cutting at all, deck yourself in thick rubber overalls, complete with thick gloves, rubber boots, and a helmet – if you have one. Also:
- Avoid loose clothing at all costs, while operating a circular saw. The cloth material might get caught in the saw’s blade, and this might have dire consequences.
- Put on safety goggles whenever you are operating a circular saw to protect your eyes from flying particles.
Carry out thorough checks on the saw before use
- Before cutting at all, test the saw blade to ensure it is sharp enough to work with. Sharper blades are safer to work with and even better, they produce more accurate works.
- Also, check the lower blade cover to ensure it retracts smoothly.
- You can also roll the saw blade manually to check if the movement is natural and devoid of hitches.
- Gauge the machine’s oil level to determine if it is at an acceptable level.
Behavior while operating a circular saw
- Never try to cut beyond where your hands can reach naturally. Overstretching to cut a tree branch might cause you to lose balance, and boy, you don’t even want to imagine what happens afterward.
- Do not try to change the direction of your saw while cutting forcefully. If you seem to be going the wrong way while cutting, switch off the saw totally and realign the blade before you resume.
- Resist the temptation to put your hands under the saw plate while in use.
- Do not force the lower blade cover open. You might damage it, and even injure yourself in the process.
- Operate the saw with both hands for a firmer grip and better control in case of any eventualities.
- Ensure the workpiece is firmly fixed in place before cutting.
FAQs related to circular saws
Is a skill saw the same as a circular saw?

Also, you will most likely experience a lot of kickback while attempting to cut a branch with a circular saw. And this can be quite dangerous to inexperienced users.
How do you mount a circular saw to the table?
Converting a handheld circular saw to a table saw is not difficult and is something that can be done within minutes. However, as with other processes involving the saw, you need to exercise caution while handling it to prevent injuries. To mount a circular saw on a table: Prepare a sturdy table with a hole at the center for you to place the saw. Create a removable panel on which you can mount the saw. Create a flat edge at the hole, using a slightly thick piece of wood and some glue. This flat edge serves as a platform for the fence, which is a piece of wood that acts as a cutting guide. Cut an appropriately sized hole in the panel, and using screws, fasten the saw to the board in a way that the majority of your hardware lies below the tabletop. Once the above is done, adjust the fence until it aligns with the saw blade. BOOM! Congratulations, you have successfully converted your circular saw into a table saw.
Can I cut steel with a circular saw?
It might not seem like it, but circular saws are capable of holding their own when it comes to cutting steel or metals in general. To successfully cut steel with a circular saw, make sure you fit it with a suitably durable blade. Also, ensure the cutting speed is not set too high.
Why does my circular saw burn wood?
If you experience scorch marks on your workpiece while cutting, it is likely due to one or both of the following reasons: a dull saw blade or plodding cutting speed. Both situations generate excessive friction while cutting, subsequently leading to higher heat production and visible burn marks on the wood. To prevent this from happening, ensure your saw blade is sharp enough to cut through wood with no stress. Also, refrain from cutting wood at abnormally low speeds.
What kind of metal is the circular saw blade made of?
Circular saw blades are typically made of steel, with the type of steel material used depends on the purpose for which the saw is intended.
How do I stop kickbacks when using my circular saw?
One thing you can do to stop getting kickbacks while operating a circular saw is to ensure you work the machine with your two hands firmly gripping the handle. Also, maintain a firm stance while cutting. Ensure the workpiece is firmly held down and carry out all cutting operations on a flat surface. Carry out regular checks on your saw blade to ensure none of the teeth is broken or distorted in some way. Do all this, and you can be sure the rate at which you experience kickbacks while working will reduce considerably.
What do you use a compact circular saw for?
Compact circular saws are lightweight equipment that you can use to make standard and bevel cuts in a wide range of materials, which include plastics, wood, and metal.
Can I make cuts in concrete with a circular saw?
