24 vs 40 Tooth Saw Blade: [Which One is Better?]

Round sawblades have between 14 and 120 teeth, which is a wide range. When you want to make a cut, use a blade with the right amount of teeth for the job. Which blade is best depends on the type of material being cut, how thick it is, and which way the grain runs in relation to the blade. 

The goal might be the most important thing to think about when picking a saw blade. A blade with fewer teeth will usually cut faster than one with more teeth, but the cut will be rougher, which doesn’t matter if you’re a framer. 

On the other hand, a blade with too many teeth makes the cut slower and burns the material, which no cabinetmaker would stand for.

The price of 24 vs 40 Tooth Saw Blade tooth varies just as much as how well they work. Blades can cost anywhere from a few dollars to over $100. How the blade is made, how much carbide it has, and how good the carbide is all affect the price the most.

The tooth on the saw blade has a big effect on the items you’re cutting. Because of this, a normal blade can’t help you finish the job. A lot of people, including myself, have trouble choosing between 24 tooth vs 40 tooth saw blade. 

We’ll talk about what makes them different, how they work, and what traits they share. Watch out!

What  Does Tooth Count  Mean:

What  Does Tooth Count  Mean

An electric saw has a blade with teeth on it that do the cutting. There are different blades with different numbers of teeth based on their purpose, so you’ll need to decide whether you want to use the blade for ripping or crosscutting.

For ripping, which cuts along the grain of the wood, you need a blade with fewer teeth than for crosscutting, which cuts across the grain.

You might not know what kind of cutting you want to do, or you might plan to do both ripping and crosscutting. 

Combination blades, which are also called “general-purpose” blades, are the best choice. They can do both ripping and crosscutting because they have more teeth than ripping blades but fewer teeth than crosscutting blades.

What Are the Purposes of Saw Blade Teeth:

The functions of a saw blade tooth are essential for cutting through various materials. Each tooth has a specific role in this process. The leading or cutting edge initiates the cut by biting into the material. 

The gullet, which is the space between teeth, carries away sawdust or waste to prevent clogging. The tooth’s rake angle determines the cutting aggressiveness, with a more aggressive angle making quicker cuts. 

The tooth’s set provides clearance, preventing the blade from binding in the cut. Collectively, these functions allow the saw blade to efficiently and accurately cut through materials, making it a crucial component in woodworking, construction, and other cutting tasks.

What Is the Purpose of a 24-Tooth Blade?

Most of the time, a 24-tooth blade is used for fast, rough cutting in building and carpentry. People call this kind of blade a sharp or ripping blade. It’s made to quickly remove material, so it’s great for jobs that don’t need a smooth finish. 

Because there aren’t many teeth, there are bigger spaces between them, which makes it easier to get rid of waste. It’s often used to cut through boards, lumber, and other things that don’t need a smooth surface. 

Even though it works very quickly, the edge it makes might be a bit rough or jagged and need more work to be smooth.

A blade with 24 teeth is often called a 10-inch “ripping blade.” This tool, as the name suggests, makes it easy to rip different kinds of materials.

It also works great for rough building. So, a 24-tooth blade is very fast, but not very accurate.

How Does It Work?

With its sharp teeth, a 24-tooth blade can quickly cut through materials. Every tooth on the blade does a certain job. The cutting edge of each tooth bites into the material as the blade turns. 

There are bigger holes between the 24 teeth, which makes it easy to remove food and other things quickly. The gullets, which are the spaces between the teeth, help get rid of trash and keep the pipes from getting clogged. 

The rough teeth quickly tear the material apart as the blade goes through it, so it can be used for rough cuts that don’t need to be polished. When speed and efficiency are more important than a smooth surface, this blade works best.

What Is the Purpose of a 40-Tooth Blade?

A 40-tooth blade is commonly used for making precise and clean cuts in various materials. It is considered a general-purpose or combination blade. The greater number of teeth, compared to a 24-tooth blade, means there are smaller gaps between them. 

This results in a smoother cut, making it suitable for tasks where a polished finish is essential. A 40-tooth blade is versatile, working well with materials like wood, plywood, and even some plastics. 

It strikes a balance between speed and precision, making it an excellent choice for woodworking and other applications where a cleaner and more refined cut is desired.

A 12-inch saw blade with 40 teeth is easier to see than one with 24 teeth. It is best for ripping and making combination cuts. It’s best to use this kind of blade to cut things like plywood, melamine, and other the like.

People who use it may find it slower than the 24-tooth but more accurate because it has more teeth.

How Does It Work?

A 40-tooth blade operates by using its numerous sharp teeth to make precise and clean cuts. Each tooth plays a crucial role in this process. When the blade rotates, the sharp leading edge of each tooth gently bites into the material. 

With 40 teeth closely spaced together, there are smaller gaps between them, which results in a smoother and finer cut. The gullets, the spaces between the teeth, help in removing waste material effectively, preventing clogs. 

As the blade moves through the material, the more teeth work together to produce a neater, polished finish. This blade is well-suited for tasks where accuracy and smoothness are important, like woodworking and cutting materials that require a clean surface.

40-tooth saw blades tend to turn a little more slowly than 24-tooth blades. Having said that, it lets you make better cuts and finish with clear instructions for spinning.

So, if accuracy is the most important thing, any builders will definitely like it.

Factors to Consider: 24 vs 40 tooth Saw Blade:

24 vs 40 Tooth Saw Blade

First, let’s talk about the main ways that the 24-tooth and 40-tooth saw blades are different. In this way, you can choose which one you want.

The Number of Teeth:

This is the initial location where the distinction between the 24- and 40-tooth saw blades becomes apparent to all. Due to the increased number of teeth, the forty teeth will be discernible on the approximately 12-inch-diameter, larger saw blade.

Size of Gullet:

If you look at your saw blade, you might see a small space in front of each tooth. When you cut it up, the amount of wood you can take off depends on its depth and size.

As a general rule, a saw blade with more teeth will have a smaller gullet. In this case, the gap between the 24 teeth on the saw blade will be bigger than the 40 teeth.

The angle of the Hook or Haw:

In general, a rake or hook angle can be between 5 and 20 degrees (+). If you look at rip blades, you can see that they pull materials like wood, melamine, and so on into the blade at an angle of about 20 degrees.


To put it simply, kerf shows how thick a saw blade cut is all the way through. Mm is usually used to measure it, and among builders, anything between 1.5 and 3 mm is considered thin.

In terms of the kerf, there won’t be a big change between 24 and 40 because the standard width is about 1/8″.

Top Flat:

The flat top, which is also called the flat top grind (FTG), is mostly used on rip blades to make cuts go faster and better. In this case, a 24-tooth saw blade might have a flat top so that it can be used for ripping.

In addition, a flat top is useful for general cutting tasks.

The angle of Bevel:

The beveled teeth on your saw blade are very important for cutting wood and other materials like that. If you look around the blade, you may see angles of 15, 10, and 20 degrees many times.

As a general rule, you can make more accurate cuts when the edge angle looks bigger. Because of this, the angle of the 40-tooth saw blade is bigger than the angle of the 24-tooth saw blade.

What  Saw  Blade Do You  Require?

Most of the time, you’ll use a saw to cut wood both with and across the grain. A general-purpose, or combination, saw blade is needed for this.  Use a rip saw blade if you only need to cut with the grain.  There is only one type of saw blade that you need for cutting across the grain.

When you make a crosscut or rip cut, you should use a saw blade for that type of cut. These blades will cut more smoothly and quickly, and they will also last longer.  A crosscut blade will save you time and money when you have to do the same thing over and over, like cutting 2x4s to length to frame a house.  

It would take a lot of time to switch between the rip and crosscut blades for jobs that need both types of cuts, so it would make more sense to use something in between.

If you’re not sure what kind of cutting you’re going to do, or if you want to do both pulling and crosscutting. Combination blades, which are also called “general-purpose” blades, are the best choice. 

They can do both ripping and crosscutting because they have more teeth than ripping blades but fewer teeth than crosscutting blades.

Bottom Line: 24 vs 40 Tooth Saw Blade

When deciding between saw blades with 24 and 40 teeth, it is helpful to do a side-by-side comparison to help narrow down your options. If speed is your primary concern, We would recommend going with the 24-tooth blade.

On the other hand, if you’re after pinpoint precision, you need look no farther than the 40-tooth for its expanded teeth.


What is a 60 Tooth Saw Blade Used for?

This is your go-to blade for slicing through oak, pine, melamine, veneer plywood, and delicate molding. This blade’s high tooth count minimizes grabbing of the workpiece, producing cuts that require little to no sanding.

What Do you do With a Saw Blade That has 40 Teeth?

40 teeth in all. Saw blade for general use. The wide blade on the Diablo is great for cutting oak, pine, plywood, pressure-treated boards, and beams. Diablo’s blade is great for table and miter saws and makes smooth cuts in a lot of different situations, so you don’t have to change blades between jobs.

What’s the Best Number of Teeth for a Saw Blade?

The TPI tells you how many teeth are on an inch of blade. From 6 to 20, TPI is the range of blades you’ll need to cut wood and other soft materials. A TPI between 14 and 36 works best for metal and other hard materials. The blade will tell you how many teeth it has.
