If you’ve recently purchased a table saw, you may find yourself puzzled over whether its table saw blades are reverse threaded. Believe me; I’ve been there! This mystery led me to dig deep and uncover the facts about the threading direction of table saw blades.
In this article, we’ll navigate the world of table saw blade threads together, explaining what it means for a blade to be reversed threaded and how this impacts usage. Stick around if you’re keen on understanding your power tool better!
Key Takeaways
- Table saw blades can be reverse threaded, meaning they rotate counterclockwise instead of clockwise.
- Reverse threading provides a secure grip and helps in fastening the blade onto the table saw for safety and firm attachment.
- Changing a table saw blade requires proper tools, including wrenches, and following necessary safety precautions like unplugging the saw before beginning.
Understanding Reverse Threaded Blades
A reverse-threaded blade refers to a table saw blade that rotates in the opposite direction compared to standard threads, counterclockwise instead of clockwise.

What Does Reverse Threaded Mean?
Reverse threaded means the thread turns the opposite way. In other words, you tighten it by turning to the left and loosen it by turning right. This is different from standard threading where you turn right to tighten and left to loosen.
When talking about table saw blades, they have reverse threads for a secure grip. They rotate counterclockwise which helps in fastening or securing them better onto your table saw.
After many years of using table saws, I have come up with the best table saws under $1500. Be sure to see which ones I have included.
Unlike miter saw blade bolts and right-handed circular saws that are not reverse threaded, a table saw uses this method for safety and firm blade attachment.
Importance of reverse threaded blades
Reverse threaded blades are key for table saws. They spin the other way than normal threads. This is because the nut would undo itself as the blade spins if a regular thread direction was used.
If you can tell the difference between a standard thread and a reverse one, it will be much easier to take care of your tools.
Not all tools use reverse threading though! Miter saw blade bolts have left-hand threading, which is the usual kind. The same goes for lawn mower blades – they only look reverse-threaded because some nuts on the mowers are made that way!
So don’t get mixed up when dealing with different types of equipment or you could mess up their care and maintenance!
How To Tell If The Table Saw Is Reverse Threaded?
You can usually tell if a thread is reversed by closely looking at the threads. A reverse thread means the nut will tighten by turning to the left and loosen by turning to the right.

A step-by-step guide to changing the blade
Changing a table saw blade needs focus and the right steps. Here is a guide to help you do it:
- First, unplug your table saw. It’s easy to forget this step, but it’s very important for your safety.
- Get your tool kit ready. You will need a wrench or two.
- Next, remove the blade guard. This part keeps you safe when the saw is on.
- Now, find the locking mechanism on your saw and lock it down. This step stops the blade from moving.
- Use your wrench to loosen off the blade nut which holds the blade in place.
- After loosening the nut, you can remove the old blade from its spot.
- Once removed, inspect your new blade before installation.
- After inspecting new blade install it in place of old one and tighten back up with nut using wrench.
Tools needed for the process
To change a table saw blade, you will need the following tools:
- Two wrenches: One wrench is used to secure the arbor, and the other is used to loosen the nut.
- Arbor: The part of the table saw that holds the blade.
- Nut: The nut holds the blade in place on the arbor.
- Washer: A washer is placed between the nut and the blade for added stability.
- Blade: The cutting tool that is attached to the arbor.
Different Types of Table Saw Blades
There are several different types of table saw blades, including Flat Top Grind (FTG) Blades, Alternate Top Bevel (ATB) Blades, Combination (ATBR) Blades, and Triple Chip Grind (TCG) Blades.

Flat Top Grind (FTG) Blades
Flat Top Grind (FTG) blades are a type of table saw blade designed for ripping through wood quickly. These blades have square-shaped teeth, also known as Rakers, with flat and square top edges.
Be sure to reveal the truth on can table saw blades be sharpened.
FTG blades have fewer teeth, larger gullets (the spaces between the teeth), and a steeper rake angle, which allows them to cut fast across long distances. They are specifically designed for cutting along the grain of the wood, making them ideal for rip cuts.
Understanding the different types of table saw blades and their tooth designs is important for achieving accurate and efficient cuts in woodworking projects.
Alternate Top Bevel (ATB) Blades
ATB blades are a type of table saw blade that is really useful for cutting at different angles. They have teeth that are angled across the top edge, which helps them make cleaner cuts.
These blades are great for cross-cutting applications because they can cut through the grain smoothly. Compared to other types of blades, ATB blades give you smoother cuts, making your projects look even better.
Combination (ATBR) Blades
Combination blades, also known as ATBR blades, are a type of table saw blade that combines the features of Flat Top Grind (FTG) and Alternate Top Bevel (ATB) blades. These blades have 50 teeth arranged in sets of five.
Some of these blades are vital when making dado cuts. I’ve compiled a list of the best table saws for dados.
Each set consists of four ATB teeth followed by one raker tooth. This tooth arrangement allows combination blades to be used for both ripping and crosscutting tasks. That’s why they are popular among woodworkers for their versatility.
Whether you need to make long cuts with the grain or smooth cuts across it, combination blades can handle both effectively.
Triple Chip Grind (TCG) Blades
Triple Chip Grind (TCG) blades are a type of table saw blade that is specially designed for cutting heavy and dense materials. These blades are commonly used for cutting non-ferrous metals, such as aluminum, as well as composite materials.
One of the key features of TCG blades is their unique tooth geometry. They have alternating flat top grind and chamfered trapezoidal shape, which helps them produce clean and chip-free cuts.
This makes them ideal for tasks that require precision cutting. Additionally, TCG blades are known for their durability and ability to withstand the demands of cutting dense materials.
