What is the best circular saw?

When it comes to choosing a circular saw, most people face a basic problem—one circular saw does not seem very different from another. If you don’t know much about circular saws, you may end up purchasing a circular saw that is not very good for your particular purpose.

That is why people who are going to purchase circular saws should educate themselves about this machine. When you know about different brands, and what qualities make a good circular saw, you can make an informed decision.

The first thing you have to know is that the drives of circular saws are of two styles.  They are called sidewinder and worm drive. Sidewinders are sometimes called direct drive. Sidewinders are very common and most customers end up purchasing this type of circular saw.

You will notice some differences in a worm drive circular saw. To run the blade, worm drive circular saws use a worm gear and as a result they are a bit longer than sidewinders. While sidewinders have the blade on the right side, worm drives tend to keep it on the left side.

Keep in mind that worm drive circular saws are more expensive than the other type. To keep them lubricated, you will need to use oil. Worm drive saws are suitable for heavy use.

But that does not mean that sidewinders can not be suitable for heavy use. There are many brands out there that will stand the test of time. Sidewinders can also last a long time even if you use them regularly.

What to look for in a circular saw

All circular saws do not have the same features. However, there are some features that make a circular saw good. It is important to know the features because if you don’t know them, you may end up purchasing a low-grade circular saw. Below are some features to look for when buying a circular saw.


When you buy a circular saw, see if the rear handle of your circular saw has a rubber surface. It will provide ease of adjustments and balance. This is one of the first things that a customer looks for. There are some circular saws that have grip on the front knobs.


You may find it difficult to handle a heavy saw, but handling will be much easier if the weight is well-balanced. Cordless circular saws are popular, but before purchasing one, you should keep in mind that these saws are often very heavy because of the batteries. The tool may be designed for heavy use, but the batteries often negatively affect the balance of these tools.

Safety of trigger

It is a good idea to avoid purchasing circular saws that too fat, too vertical and the trigger buttons are not easy to push. Good circular saws are designed in such a way that the trigger safety buttons are within the reach of your thumb. Your grip is compromised when you reposition your hand for squeezing your thumb inward. You will find it awkward to start a saw if you need to move your finger to get a good grip of the safety trigger.

Bevel angle

If your saw has marks every one degree, you will find it easy to set the bevel angle. Etched marks are longer lasting than painted ones. Parallax errors are reduced and setting precision is increased if definite pointers are down close to the degree marks. Choose circular saws that have strong visual contrast of bevel scale and pointers.


Accurate cutting marks, smooth guard retractions, and blade visibility are important because they make working with a circular saw more effective. If the cutting markers are good, they will line up exactly with the kerf. The notch should not be wider than a thin-kerf saw blade. If a notch is very wide, you can not rely on it.


You can not always clearly see the cut line. That is why the blade should be visible. When the blade faces away, you will find it difficult to have a clear view because lower guard retracting lever, upper guard housing or your hand. It is a good idea to keep the saw set at its maximum depth when you make cuts.

Power sources

While sidewinders are mostly cordless, worm drives and hypoids are corded. If you use a cordless circular saw, you will not have to worry about managing a cord when you make cuts. You also do not need a power outlet nearby. Since cordless circular saws use batteries, they are less powerful than the other types. But these saws are safer than corded saws.

Electric brakes

Although electric brakes are a great safety feature, all circular saws do not have the feature. When you release the trigger, electric brakes slow down the blade. If your saw does not have a brake, the blade keeps spinning for a long time. It may result in injuries if you are not very careful.

Cutting depth and capacity

It is important to check the cutting capacity of the circular saw you are going to choose. What you need to check is the size of the blade. For circular saws, the blade is usually 7-1/4 inches. Bigger and smaller saws are also available. Proper cutting depth ensures accurate cut. If the saw is 7-1/4 inches, you can cut 2 inch lumber with the saw, at 90 or 45 degrees.

Extra features

There are some circular saws that provide a few bonus features. On such feature are hanging hooks. They allow you to hang the saw when you are not making cuts or resting. When you work indoors, LED headlights are really helpful. For taming airborne dust, dust ports are pretty useful.

Circular saw FAQs

1. What is the reason of the chipping of my material?

If you select a poor blade for the application, material is likely to chip on the bottom of the sheet. A negative rake saw should be used to cut melamine. And the tooth spacing should be about 1.5/4 of an inch.

2. When the cut comes to an end, the material chips. Why? 

In most cases, poor blade alignment causes this. The potential causes may also be poor arbor and spindle bearings. It is a good idea to use a close fitting throat plate.

3. When the blade exits the cuts, I get heavy kerf lines. Why?

The most common cause of poor blade alignment is poor blade alignment. To learn about proper alignment, use the manual of your machine. Read it carefully and you will understand the mechanism.

4. The blade cuts properly only on one side. Why?

A faulty blade causes this problem. This problem may occur for blade dish, improper tension or side clearance.

5. Why do I experience burning of the material while ripping?

There may be several reasons for burning of materials. An improper alignment of the fence can cause this. If your blade is heeling, it may be another cause. Burning of material may also be because of a dull blade. Apart from these reasons, if the stock shifts off axis, it may lead to the burning of material. For good results, it is a good idea to use a 50-tooth combination blade.

6. What is causes the vibration of the blade?

If the blade is mounted improperly and the arbor and collar are not clean enough, the blade may vibrate when the saw reaches maximum RPM. Check to see if they are okay. You can also check the arbor to see if it is bent.

7.Why is my cut wider than my blade kerf?

Most probably the blade is not properly aligned to the fence. The material should also be parallel to the blade. Check to see if the blade is aligned properly.

 8.Why does the neck of a tooth break?

It can happen if you set the blade too high. To avoid it, make sure that the primary blade gullets clear the top of the workpiece. In fact, you don’t need to set a blade high if the blade is sharp and the saw is well-tuned.

9. When should I choose a circular saw rather than a band saw?

The main advantage of using a circular saw is the speed of cutting. You must consider the diameter and finish. If you need to cut fast and you are working with a material of small diameter, you should choose a circular saw.

10. Why am I getting resin on my blade?

If the RPM is too high, heat will be created between the blade and the material. In that case, resin may build up on the blade. There is another potential reason. If the blade is used with too many teeth for the application, you may end up having a coating of resin on your blade.

Knowledge about circular saws

A circular saw is an electric saw that uses a round, flat blade. It is used to cut wood, plastic or metal. The saw contains an on/off switch. Circular saws also have bevel and height/depth adjustments. It should be noted that a ring saw and a hole saw also use a rotary motion, but they are not the same thing as a circular saw.

Circular saw specifically refers to the hand-held saws. There are other types of circular saws such as table saw and chop saw, but they are not commonly called circular saws.

All circular saws are not intended to cut all types of materials. The blade of a circular saw is specifically designed to cut wood, metals, plastic or other types of materials. Although circular saws are usually powered by electricity, there are some models that are powered by gasoline.

Carpenters and builders can not go a single day without this handheld power tool. Circular saws can make the jobs of cutting quicker, easier and more efficient. The blade size of your saw will depend on your project. For example, if you need to cut thin planks of wood, you may need a 6.5” blade. But if you need to cut cement or materials like that, you may need a 12” diameter blade. Both beginners and professionals like this very useful tool.

History of circular saws

It is not known who invented the circular saw, but it is pretty clear that this tool was invented around the end of the 18th century. In the beginning, sawmills used smaller diameter circular saws. With the advancement of technology, large diameter saw blades began to be used.

It is claimed that a sailmaker named Samuel Miller obtained the patent for a saw windmill in 1777. But others think that he was not the inventor of this tool. It is often claimed that a man named Gervinus who lived in Germany invented the circular saw in 1780. In 1762, a man from Southampton named Walter Taylor built sawmills and roughed out the blocks. Again, some historians claim that circular saws were originated in Holland in the 17th century.

Basic features of a circular saw

There are many types of circular saws; so the features vary a lot. But there are some basic features that all circular saws have. Before you buy a circular saw, you must check the features of the circular saw you are going to work with. Making a choice will be easier if you know about the basic features of a circular saw.


The blade of a circular saw is very sharp. You can set the depth of a circular saw blade for individual cuts. It gives you more control over the tool. To adjust this blade, use the adjustment lever at the rear of the motor. If you need to make delicate cuts, you can set the blade even to as little as 0.5”.

Base plate

All circular saws have a square shaped base. To help you determine the precise measurements of your cuts, there is a metric ruler printed on the base plate. Measurements are usually made in a circular motion.

You can adjust the base plate to just about any angle. For making angled cuts, you can tilt it. To make sure that you achieve accuracy, stick to the scale.

Blade guard

A blade guard is a part of every saw. It ensures safety when the saw rotates. You will run the risk of getting injured if your circular saw does not have a blade guard. Blade guards are usually of two types: fixed guard and floating guard. A fixed guard is always fixed over the top of the blade, but a floating guard can be moved.

Ripping fence

Most circular saws have ripping fences. When you make your cuts, the ripping fence guides the blade. It helps you make a ripping cut. To achieve a smooth and accurate cut, this is a quick way.

Dust ejector

When you make cuts with a circular saw, a dust ejector does not let sawdust come to your face. Most models of circular saws come with a dust ejector to blow sawdust away.

Types of circular saws

There are a few types of circular saws. To help you decide what the best choice is for you, we are going to focus on different types of circular saws.

1. Sidewinder


The sidewinder is a compact circular saw. Its motor is mounted on the side of the saw. As a result, the motor rests on the solid workpiece, not on the cutoff portion. This type of circular saw is ideal for overhead cutting, because it is very lightweight.

2. Worm drive saw


This circular saw is a bit longer but narrower than a sidewinder. Two gears are situated at a 90 degree angle, and they transfer power to the blade. The gear provides more torque but reduces the blade speed. This saw is good for cutting wider boards. A drawback of this saw is that it requires a bit more maintenance.

3. Hypoid circular saw


Although hypoid circular saws look like worm drive saws, they are different. It has a different kind of transmission and gearbox. It has more power and efficiency but makes less noise. The saw has a sealed motor system that does not require oil. A hypoid circular saw is heavier than a sidewinder.

You may need a circular saw with a left side blade or right side blade. If you need blade on the left side, you should choose a sidewinder. Worm drives or hypoids have blades on the right side. The choice depends on your personal preference and whether you are right-handed or left handed. It is a good idea to try several types of circular saws and figure out which one works best for you. Keep in mind that one type is not necessarily better than another. The choice depends on your project. Educate yourself and choose the best circular saw.

How to use a circular saw

A circular saw is an incredibly useful tool. It is capable of making just about any straight cut. Rip cuts, cross cuts, miters, bevels and even dados are possible with a circular saw. You need the patience to set up the saw properly. They are a great way to break down sheet goods like plywood without having to wrangle a huge sheet through a table saw. Circular saws are incredibly portable. So you can easily do any of these cuts at a jobsite.

A circular has two handles at the front and rear of the saw. The rear handle has the safety switch and trigger. The front handle provides added stability when cutting. The shoe or baseplate rests on top of the lumber you are cutting. It’s also used to set the depth and angle of your cut.

The blade guard surrounds the plate. It protects the blade if you leave the tool sitting on the ground. It also protects you when the blade is spinning. The blade guard automatically retracts when making a cut. You can also manually retract the guard using the lever. It is useful when making plunge cuts.

The shoe has a number of markings on it. The most important one is the notch which indicates the location of the blade. You can use the level to set the cut depth.

You only want your blade to be extending a tiny amount below the depth of your material. Cutting too far through is not only dangerous but it also makes harder work for the saw.

There is a lever to set the angle of the blade. On most saws there are positive stops for 90 degree and 45 degree cuts.

Like any power tools, should be wearing safety glasses for every single cut. If you are making a lot of cuts, protecting your ears is a really good idea.

The sawdust from a circular saw is not as fine as other tools; but it’s still a good idea to wear a dust mask.

To make a cut, just rest the shoe of the soft flat on the lumber you are going to cut. Pull the trigger and let the blade spin up to full speed. Then push the blade smoothly through the material using the notch to guide your saw along your cut line. Don’t push the saw too quickly. Just let the blade do the work.

When your cut is complete, push the blade completely clear the material. Release the trigger and wait for the blade to come to a complete stop.

It’s important to let your off cut fall freely. You don’t want your wood to be supported on both sides. If it is, your wood can pinch your blade as you make your cut. And the saw will start to climb its way out.

If any kickback happens, release the trigger and lift the saw clear and reposition your wood before continuing.

How to choose the best circular saw

Carpenters and professional craftsmen use circular saws to make a variety of cuts. A circular saw is in fact one of the most useful cutting tools because almost any kind of cut can be done with this saw. To cut timber, lumber, concrete board and paneling, a circular saw has a round blade edged with sharp metal teeth.

To choose a good circular saw, you need to know some facts about this tool. In this post, we will show you how you can choose the best circular saw, whatever your purpose is. Here are some important things to consider when you purchase a circular saw.

Cut line indicator

You will find it in front of the saw’s baseplate. The cut line indicator is important because it helps you line up your blade with your cut line. A good marker helps you cut to either the left or right side of your line.

Blade visibility

You can not always see the cut line indicator. In that case, blade visibility is very important. It will help you know if the blade is on the line. If the saw is of good quality, you will be able to see the blade clearly through the window. It will be clearly visible even when your hands are on the tool.

Bevel function

Although you will not use it very often, you must have an accurate setup when you need to do a complicated framing. The bevel level of a high quality saw is comfortable to operate with. It also locks securely. Good saws also include an override function that is easily operable. If needed, you can go beyond 45 degrees.


The baseplate of your circular saw is another important thing to consider. If your baseplate is made of stamped aluminum, it will bend easily, but you can also fix it quickly. On the other hand, your baseplate will be less prone to bending if it is made of cast magnesium. If this type of baseplate is cracked, you can not easily fix it. There are also baseplates made of fiber-reinforced plastic. These baseplates are tough and stiff.

Guard retraction

If the guard gets stuck and does not retract, you have no other option but to stop working and loosen the saw. Sometimes the experience can be very frustrating for you. A good saw has a large lobe above the main edge of the guard. When you need to cut in angles, the saw may get stuck if it has sharp leading edges. To avoid unwanted situations, make sure that the guard retracts.
