Circular Saw Blade Types: 5 Things You Need To Know (Before Purchasing)

circular saw blade types

The circular saw is a powerful rotary motion saw very commonly used in the USA. Its teeth are in constant motion and will cut various materials from plastic to solid wood.

There are plenty of different blade types available, but each of them has specific usage cases. You need to be aware of precisely what you would like to cut to determine your circular saw’s right blade type.

We will explain the differences in blade types for circular saws and guide you through each one’s pros and cons.

What You Need To Know about Circular Saw Blades

Your circular saw is a tool that can help you fix your interiors and exteriors at home. It is a powerful tool that can help you create something sturdy, beautiful, and functional. To have the best saw blade that serves your purpose, here are a couple of things to keep in mind while buying one.

Saw Plate Thickness

A saw plate is generally 1/8th to 1/4th inch thick, depending on the material you are cutting. It also depends on the cost of your project. Ideally, a thick blade will give a sturdy and clean finish. However, it could result in wastage and bring your costs up. 

A thin blade will help you save your fine material. The con of a thin kerf blade is that it is delicate. Moreover, it is prone to heating and wobbling. This gives it a wavy and uneven cut. So, choose your blade thickness based on your project. 

Saw Tooth Design

The saw tooth design helps determine the kind of cuts the circular saw makes. Remember, the number of teeth also plays a role in your circular saw. 

If your saw blade has a greater number of teeth, you’ll be able to make slower, smoother, and finer cuts. In contrast, a saw blade having lesser teeth makes shoddy-looking, quick work. You also have different types of tooth designs depending on the cuts you want to make. 

Flat Top Grind

These blades have a flat top like the name denotes. They are used to rip apart the material. They work based on speed rather than precision. These are popular in rip blades. Plowing through the wood quickly without overheating is the priority of this design. 

Triple Chip Grind

The triple chip grind is like the FTG except, the edges of this design are beveled. The TCG predominantly used a combination of the FTG and chamfered FTG.  This is a durable type of teeth design for a circular saw blade. It is used to cut laminates as well as other manufactured materials. 

Alternate Top Bevel  

The Alternate Top Bevel or ATB teeth design cuts just like a knife. It helps in scoring the wood and giving you a more refined finish. It is used for general purposes and gives you a beveled bottom. The ATB helps in crosscutting and gives you a smooth and clean cut. 

Veneers and laminates that need smoothness require an Alternate Top Bevel circular saw blade for cutting. Note that these blades are not built for speed and dull faster due to the bevel’s angle. 

Hook Angle

Hook angle shows the direction in which the tooth enters the material being cut. There are two types of hook angles, positive hook angle, and negative hook angle. In a positive hook angle, the teeth are faced forward. Whereas in a negative hook angle, they are faced backward. 

A positive hook angle helps rip and fast moves. The negative hook angle will help you in crosscutting wood. However, if you want a saw blade that helps you in ripping and crosscutting, look for zero hook angle.

Tooth Material

The saw blade material is as important as its size and safety features. The stronger the material of your blade, the more its precision in cutting the material you want. Steel is the most commonly used material for a saw blade tooth as it is strong, durable, and sharp.

In the present time, carbide is the material used for the circular saw blades. It is a combination of tungsten, cobalt, and carbon. Carbide blades are long-lasting, corrosion-free, and resistant to friction. Only, they can be brittle and difficult to sharpen once they become dull. 

Another material that can be used to make a circular saw blade is diamond. Diamond is the hardest material that we know. It is sharp, strong, and conducive to cutting hard-to-cut materials like concrete, stone, and asphalt. 

Irrespective of tooth material, plan your budget so that you can get an Anti-Friction coating on your circular saw blade. The coating is mostly of Platinum, Iridium, Teflon, Chrome, or Titanium. This coating prevents overheating, corrosion and makes the blade more durable. 

Here Are The Different Circular Saw Blade Types

There are several types of circular saw blades, each with its own pros and cons.

5 Hollow Ground Blades 

Hollow ground blades are used for extra-fine crosscutting. Generally, we use carbide blades for this purpose. 

Pros 

  • Ultra-smooth cuts
  • Cuts coated material like laminates easily
  • Extremely sharp and precise

Cons 

  • High friction levels
  • Prone to overheating

Pros

  • Specifically for plywood
  • Fine cutting

Cons

  • Not used for other materials

  • Prone to overheating

8 Ripping Blades 

You use these FTG blades to plow through wood. They cut along the grain only.

Pros

  • Fast speed 
  • Move through larger chips of wood

Cons

  • Don’t give a smooth finish
