A circular saw is one of the most popular and widely used table saws that can help you cut through various kinds of materials, including wood, plastic, metal, etc. While chop saws are rugged and relatively simple tools for cutting lumber, circular saw blades are specialized for breaking down sheet metal. They feature a toothed or abrasive blade that has to be guided downwards on the workpiece that you must cut. Usually, circular saws are mounted onto a work table, but they can also be found in handheld variants. Cordless saws that run on two 18V batteries are practical and highly opted tools for tough jobs.
The most critical component of the circular saw is its blade, and the type of blade you use for cutting through different materials determines how smooth the operation will be. If the current blade on your circular saw has finally been subjected to many hours of wear and tear, and you are looking for a replacement blade, then we have the right ones for you.
We have selected the best circular saw blades for 2023, so you can take your pick from among them. The list has been curated by evaluating hundreds of options and choosing the best ones by applying certain factors. Let’s review all of the options one by one.
Finding The Best Circular Saw Blades: A Buying Guide
What is a Circular Saw Blade?
A circular saw blade is a particular type of blade that works well with circular saws and is mainly designed to easily cut through different materials. The materials that you can cut with circular saw blades include wood, engineered wood, plastic, ferrous and non-ferrous metals, etc. Different types of circular saw blades vary according to the material they can cut through.
Why Do You Need a Circular Saw Blade?
A circular saw blade is a highly efficient accessory that enables you to cut through various materials smoothly and without leaving any rough edges or splinters. The best part of this blade is that you can use it to cut through the material whenever it is in motion, and you don’t have to worry about a return stroke, as is the case with some other types of power saws.
Circular saw blades are reinforced and strengthened to provide the smooth and optimum performance that you experience from your circular saw. Once the blade inside your saw becomes warped or worn out, you can replace it with a similar one to ensure that you keep getting precise and clean cuts every time you use it. You should consider whether or not you want a mini circular saw or a full-sized one depending on the cuts you want.
Circular saw blades are specially designed to withstand the heat generated by the motor, as well as the friction created when it comes into contact with the material. Most of the other blades often get overheated and warped, but this isn’t something you experience with the circular saw blade. Circular saw blades also facilitate making angled cuts, bevel cuts and rip cuts as well. This makes it an overall useful accessory to have.
Things To Consider Before Choosing a Circular Saw Blade
Before you go about choosing a circular saw blade to replace your existing one, make sure that you have taken all the factors into account, so that you end up with the right product in your cart. Let’s have a look at the various factors that come into play when you are choosing a powerful saw blade.
Number of teeth
Circular saw blades come with numerous teeth counts, ranging from 14 to 120 teeth. The number of teeth a circular saw blade has played a major role in your choice of one. Blades that have more teeth tend to provide a cleaner and smoother cut, whereas those with fewer teeth would have a rougher finish. Usually, a 24-tooth circular saw blade, is preferred by many people for metal cutting, especially if they have to cross-cut lumber and sheet materials.
The 24-tooth blade is good enough for you if the diameter is 7¼”. However, as the diameter increases, you should also consider looking for circular saw blades with more teeth.
The hook refers to the position at which the teeth of the circular saw blade come in contact with the material. Also known as the rake angle, it determines how fast and smooth the cut will be, as well as how quickly the waste material will be removed. If the blade has a positive rake angle, it performs a climb cut and pulls the material in. This can be harmful if you are dealing with a harder material like metal.
On the other hand, a negative rake angle has smoother performance and doesn’t pull the material towards itself. Although this is much safer, it is rather slow and removes less waste from the workpiece.
Kerf is another important factor that you must consider while choosing the best circular saw blade, and it refers to the thickness of the tooth, which can also be called the cut width. This also means that the thinner the kerf would be, the smoother and more refined the cutting performance would be. However, thinner kerfs are also prone to vibration or wobbling, which means that they may not cut hardwood precisely.
The type of circular saw blade that you use for your woodworking or other projects also matters when you are exploring different options. This also impacts the performance you get out of your circular saw. The most common type is the standard circular saw blade, which is used to cut wood or composite materials. The speed and finish of the cut are determined by the number of teeth it has.
Similarly, you can also find rip-cut circular saw blades, which have fewer teeth and work more aggressively towards cutting through wood. Crosscut blades have around 40 and 80 teeth and are suitable for clean cutting.
Apart from this, you can also buy continuous rim blades, which are also known as diamond blades and are used on tiles and ceramic materials. On the other hand, turbo-rim blades are also diamond blades, but their rim is specially designed to cut through brick and concrete. A diamond blade is considered appropriate for cutting porcelain tiles. Apart from these, you can also find segmented blades, abrasive blades, stacked blades, and many others for metal cutting.
You can choose the type you want according to the material that you need to cut, and the number of teeth will determine how smooth or rough the cut will be. Make sure to factor this in while choosing the best circular saw blade for your projects. Considering the wide range of table saws available, selecting the correct blade for smooth cuts like metal cutting can be quite daunting. The video from ‘BuildersSA’ explains the different circular saw blades and the importance of each blade to make your search easier.

People Also Asked
Q: Is there a universal circular saw blade that I can use for all materials?
No, there isn't. You will find different types of circular saw blades for each material because one single blade can’t provide you with the functionality and features that you need to cut through all types of materials.
Q: Which blade can be used to make the cleanest cut?
The cleanest cut, at least on wood or composite materials, is made with the help of a crosscut blade, which removes less material and provides a smoother cut. As precise as it is, it also takes more time to cut through wood.
Q: How long does a circular saw blade last?
A circular saw blade lasts anywhere between 12 to 120 hours of continuous usage, and the duration depends on its quality and the materials from which it is made.
Q: Can I install a circular saw blade backwards?
It can be incredibly dangerous and harmful if you install a circular saw blade in the reverse position, except for a few select materials where it can actually be beneficial. However, it is quite risky and you should avoid it.
Q: Why should I consider replacing my existing circular saw blade?
You may choose to replace circular saw blades in your power tool if it has become blunt due to excessive wear and tears. You may also choose to replace it if it has gotten damaged or rusty.
