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
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.
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.
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.
