What Tooth Count Means?
In simple words, tooth refers to the sharp and pointy objects of a saw blade designed to cut or smash different materials.
And the tooth count means the actual number of teeth included on the blade. Depending on the model, you can get multiple types out there.
For instance, a saw blade of 10-inches generally features 50 teeth. Also, a 12-inch blade consists of not less than 60 teeth in general.
What Are the Functions of Saw Blade Tooth?
In order to ensure smoother and more even cuts, the saw blade tooth plays a significant role. That’s why your blade can make more precise cuts if it includes more teeth.
In contrast, a saw blade with fewer teeth can eliminate more material. Each has its own specialties.
24 Tooth Saw Blade
What Is A 24 Tooth Blade Used For?
Note that a 24-tooth blade is commonly known as a 10-inch “ripping blade.” As the name suggests, it assists you in ripping several types of materials without much effort.
Moreover, it highly suits rough carpentry. So, a 24-tooth blade has excellent speed yet lags in accuracy.
How It Works?
In a nutshell, a 24-tooth ripping saw blade runs quickly to cut up metal, wood, or such objects following a specific direction.
It rotates in such a way that each tooth directly points to the material you want to cut. And yes, you’ll find it faster than the 40-tooth saw blade.
40 Tooth Saw Blade
What Is A 40 Tooth Blade Used For?
Unlike the 24-tooth blade, 40 tooth blade is noticeable on a 12-inch saw blade that is ideal for ripping and combination cuts. The best use of such a blade is to cut plywood, melamine, and such objects.
Due to its extended number of teeth, users can find it comparatively less speedy yet more precise than the 24 tooth.
How It Works?
In general, 40 teeth saw blade rotates a bit more slowly than the 24 teeth. That said, it allows you to have more quality cuts and to finish with its précising spinning directions.
So, if accuracy matters most, any carpenters will undoubtedly find it a great choice.
24 vs 40 Tooth Saw Blade Additional Factors
Let’s get straight into the common differences between the 24 and 40-tooth saw blades without further ado. Thus, you can decide which one you’re searching for –
Number of Teeth
This is the first place where anyone can notify the difference between the 24 and 40-tooth saw blades. Because of the extended number of teeth, the 40 teeth will be noticeable on the bigger saw blade that is of 12-inches or so.
If you observe your saw blade, you may notice a tiny space in each tooth’s front. The depth and size of it determine the quantity of wood you’re allowed to take off while cutting up.
As a rule of thumb, if your saw blade has more teeth, then it will have a short gullet size. In this case, the gullet size of a 24-tooth saw blade will be larger than the 40 teeth.
Hook or Rake Angle
A rake or hook angle’s standard range can be anywhere around 5-20 Degrees (+). On rip blades, you can notice a positive angle of around 20 degrees in terms of pulling the material into the saw blade, especially the wood, melamine, and so forth.
In a word, kerf refers to highlighting the overall thickness of a cut made by a saw blade. It is usually measured in mm, and the range between 1.5-3mm is counted thin among carpenters.
Generally, you won’t notice any significant difference between 24 and 40 in terms of the kerf, as the standard width is around 1/8”.
The flat top, also known as flat top grind (FTG), is utilized mostly on rip blades to ensure quicker and more efficient cuts. In this case, a 24-tooth saw blade may include a flat top to be compatible with ripping.
Furthermore, a flat top aids in general cutting purposes as well.
For scoring the wood or other such materials, teeth beveling on your saw blade plays a key role. 15, 10, and 20 degrees; these are some of the common angles you may notice around the blade.
In general, you can make more precise cuts in case the bevel angle appears greater. As a result, you’ll find the 40-tooth saw blade’s angle greater compared to the 24-tooth saw blade.
Comparing 24 vs. 40-tooth saw blades makes it easier to decide which one can be your ultimate cup of tea! I’d say go for the 24-tooth blade if speed matters most.
In contrast, if you’re hungry for accuracy, simply rely on the 40 tooth for its extended teeth.
