Every once in a while, you need to replace your saw’s blade if the current one is worn out. You may also be required to change it when cutting different materials, which is quite common when working on different projects.

If your saw requires a circular blade, there are different types and varieties to choose from in the market, and this might make the selection process a bit challenging if you don’t know what to look for.

However, this review covers 10 of the best circular saw blades that you should consider buying.

What To Check Before Buying Best Circular Saw Blades

1. Types of Circular Saw Blades

Standard Blades

This is the commonly used type for cutting wood and wood composites. With these, the most important thing to check is the number of teeth. Generally, few teeth mean the blade cuts faster but creates a rough finish. Many teeth cut slowly but leave a smooth finish.

That said, for ripping, you need a blade with few teeth (not more than 50) so as to cut aggressively. They should also have deep gullets for quick chip removal.

On the other hand, for plywood and chipboards, a blade with many teeth (above 50) is recommended so as to create a clean finish.

Continuous Rim Blades

As the name suggests, these blades have a continuous rim with no teeth. Instead, the edge is fitted with hard synthetic diamonds, which create a very clean finish when cutting tiles and slates. However, with these, check whether the piece is meant for dry or wet cutting application.

Turbo Rim Blades

These blades are similar in design to the continuous rim blades above but are fitted with serrated rims so as to cut aggressively through concrete, bricks and other masonry materials.

Segmented Blades

Segmented blades are also fitted with diamond edges, but this edge is divided by deep gullets. This design makes the blade very aggressive, with the ability to cut harder materials, but leaves a rougher finish.

Abrasive Blades

This type is made using abrasive compounds such as silicon carbide or aluminum oxide and does not have teeth. The abrasive material is responsible for cutting and is suitable for working on masonry materials and metal.

2. Blade Size

A blade’s size is measured in inches across the diameter. There is an advantage to having larger blades because they give a larger depth of cut, meaning that you can cut thicker materials. However, you need to make sure that it fits in your saw.

3. Arbor

An arbor is the center hole through which a saw blade mounts to a circular saw. It is important to check the size of this hole for compatibility purposes because the blade must fit into your saw.

4. Kerf

Kerf refers to the thickness of the blade and more specifically, the width of the tooth at its widest point. Thinner blades give minimal wastage because the area they cut out is very small, and also cut faster due to the reduced resistance.

However, they are not as durable as the thick ones. If you are dealing with very hard materials, ensure you get a thick blade so that it does not break.

5. Hook Angle

Hook angle is the angle of the position of the tooth as it gets into contact with the surface being cut. A high, positive hook angle points towards the surface, creating a rough, aggressive cut with a faster feed rate.

On the other hand, a blade with a low, negative hook angle cuts slower, smoothly, and with reduced chances of kickbacks. If you want a smooth finish, a low hook angle is best.

6. Coating

Some circular saw blades are coated with a non-stick material to reduce friction and gumming. This coating also helps in preventing corrosion for durability purposes. It is important to check for this factor because it directly affects the performance and longevity of the blade.
