Best Circular Saw Blades

Many people disdain the 7-1/4-inch circular saw. They say that it’s only good for cutting lumber for house framing or concrete forms. While the saw is ideal for those purposes, you can also use it to make furniture-grade cuts in wood, cut steel or aluminum, reduce unwieldly sheets of plywood to more manageable sizes, and do heavy demolition cuts through lumber that has nails in it.

The saw’s versatility is enabled by the right blade, matched precisely to the job, whether it’s cutting a thick piece of structural steel or guiding the saw along a fence to cut plywood cabinet parts to finished dimensions. Of course, proper technique helps, and you need a heavy-duty extension cord, a pair of safety glasses and some hearing protection. And we have some selections to help with that, too.

You may buy the most expensive circular saw out there, but ultimately, the quality of your cuts will only be as good as your blades are. That’s why it is important to buy the best circular saw blade for your particular line of work.

In this guide, you will learn what you have to consider when looking for the best circular saw blade. You will also find reviews of five best-rated circular blades that are worth your money.

What Circular Saw Blade Do I Need?

The cut performed by the blade actually comes solely from the teeth, rather than the disk itself. Therefore, the type of teeth on the blade you choose will have the biggest impact on the material. Choosing the correct tooth-type is essential, both in terms of cut quality and personal safety.

First of all, the greater number of teeth on the blade denotes a finer, more accurate cut.

The high number of teeth, coupled with the thinness of the blade, means that it’s ideal for fine, accurate cuts in parquet and laminates. And because the teeth (or blades) are made of tungsten carbide, they’re extremely hard wearing and they can be re-ground, allowing you squeeze plenty of working life out of them.

Another factor to consider is the shape of the blade’s teeth. The shape of the teeth cut into the tungsten blade affect the quality of the cut you’ll achieve. Some examples of shaped teeth are alternate top bevel. This is where one bladed tooth slopes one direction, the one behind it slopes in another direction. Teeth like these are ideal for fast cuts, perhaps through rough wood, particularly along or across the grain.

Benefits of Circular Saw Blade

  • Safety. Making cuts with dull or the wrong blade is hazardous. Many things can go wrong, very few of which don’t pose a threat to your well-being.
  • Make proper cuts. Using the right blade is also beneficial to the workpiece. A blade that can precisely cut through the material as you need it reduces the risk of causing damage to the workpiece.
  • Compatibility with machinery. As aforementioned, a wide range of saws use circular blades. And while you may not have more than one to work with at this point, you may get more use out of a single saw blade than you may anticipate.

Types of Circular Saw Blades

METAL

As you can gather, metal blades are designed to cut through metals. That isn’t to say that all blades in this category are the same, though. You have the option to select between a traditional design featuring teeth or an abrasive blade that closely resembles what you would use on your rotary cut-off tool.

Which you should use balances itself on a few factors, perhaps the most important being the tool you are using. As a rule of thumb, abrasive blades are meant for machines that produce high speeds, while the traditional type is better that work at lower operational rates.

WOOD

It’s just as likely that you’ll be using a circular saw blade to cut wood as you would metal. And like metal blades, there’s a wide variety out there. When selecting a blade for cutting wood, you need to be mindful of the type of work you perform. There are blades for making rip cuts, cross cuts, and the combination of either. Not using the correct one will produce low-quality cuts or even ruin the workpiece.

MASONRY

Of course, there are a bunch of different kinds of masonry saw blades as well. On top of cutting different materials, masonry blades are also designed to make wet or dry cuts. It’s imperative to make the right decision on what blade to use based on your environment and the work you are performing.

Features to Consider Before Buying

If you are using your circular saw quite a lot, then its blade can get blunt over time. While you can sharpen it, buying a new one is the best idea. Although there are various things that you have to consider before buying a saw blade. We are here with a detailed buying guide. You can follow this buying guide until the end and learn various factors related to circular saw blades as you can find the following factors:

Blade Size

As you would expect, different circular saw blades out there have different sizes for different applications. While bigger blades are made for heavy-duty usage, smaller blades are made for more compact circular saw blades. Some options are 8 inch in diameter while others are 12 inch in diameter. You can choose either of these according to the supported blade size of your saw.

Teeth Count

If you are familiar with circular saw blades, then you must know that these have small teeth for cutting easily into wood or metal. Due to this, the number of teeth offered by a given saw blade is quite important to check. This includes options like 60 teeth blades or 40 teeth blades as per the model that you buy. When compared with each other, the higher teeth count of 60 teeth offers higher precision and sharper cuts.

Arbor Size

The arbor size is one of the most important things to check before buying a circular saw blade to ensure that it is compatible with your saw. Most of the options out there include an arbor size of ⅝ inch as it is the standard size. Although, some other models might include a ⅞ inch arbor size and it is something that you should keep in your mind before buying a circular saw blade.

Durability and Warranty

After using your circular saw blades for a long time for cutting wood and metal, it can get a lot of wear and tear. Due to this, you might even have to change the blades again and again. Although to prevent this issue, you can simply get a durable and reliable blade. The easiest way to ensure that a given circular saw blade is durable is to check its warranty. While most options come with a 1-year long warranty, a few models out there might offer a lifetime warranty for peace of mind.
