Right-handed circular saws are not reverse threaded. Conversely, the blade secures with a bolt of the opposite threading. So a left-handed saw would require a regular threaded bolt. A right-handed circular saw, on the other hand, would require a reverse threaded bolt. The same is true for table saw blades.
Table saw blades are reversed threaded if they tilt right. Read on to learn about reverse threading, choosing the right saw blade, and how to change out your blades. In short, table saw blades can be reversely threaded.
Once you understand that circular saws are reversely threaded, you need to follow on how to tighten your blade on a circular saw. The aspect is crucial in the sense that it helps in determining the type of spanners to utilize in tightening the blades of these kinds of saws. You need to keep checking the blade on the circular saw periodically to ensure that it is aligned and tightened correctly.
In order for the mounting bolt to stay tight, the threads on the bolt must tighten “Opposite” of the rotation of the blade… otherwise the turning of the blade would eventually cause the bolt to turn out! Therefore, if the blade on your saw rotates counterclockwise, then the bolt is tightened clockwise. Right-handed circular saws all have blades that turn counterclockwise… left-handed saw blades turn clockwise. If your saw does not have such a built-in blade lock, clamp a pair of Vise Grips or a clamp to the blade and turn the blade till it is locked in place.
So a left-handed saw would require a regular threaded bolt. A right-handed circular saw, on the other hand, would require a reverse threaded bolt. In general, the blades on right-handed circular saws turn counterclockwise, so you’d tighten the bolt clockwise; the blades on left-handed circular saws turn clockwise, so you’d tighten the bolt counterclockwise.

are circular saw blades reverse threaded Related Question:
Are chop saw blades reverse threaded?
Yes, it’s a reverse thread (I spoke with a few tool repair shops).
Are there right-handed and left-handed circular saws?
From what I’ve seen these past few years, corded circular saws are mainly right-handed saws. There are some brands, such as Milwaukee, that offer both right- and left-handed saws. Worm drive saws are typically left-handed. Cordless circular saws are typically left-handed as well.
How can you tell if a saw blade is backwards?
The proper direction of the blade’s teeth depends on the type and model of the saw. Be sure to check the arrows on the blade to determine the rotation. Hand saw: If you’re using a non-motorized hand saw for cutting wood, the blade’s teeth should always point in a downward direction.
Where is the arbor lock on a circular saw?
Place the saw on a wooden surface and pull back the blade guard. If the saw has an arbor lock button on the top of the housing, press it in. The arbor is the shaft the blade installs on. If there’s no lock button, press the blade into the wooden surface.
Why are circular saws backwards?
Traditionally, all worm drive saws operated in a blade-left orientation. Furthermore, this orientation likely places the weight of the saw over the portion of the material the user wants to keep, making it easier to stabilize the saw during the cut.
Why are so many circular saws left-handed?
The placement of the cordless saw blade, on the left side, gives you a clearer line of sight when you cut. The reason for this is because the main bulk of your circular saw is not blocking your view. Cordless circular left-handed saws provide you better movability.
Can you run a saw blade backwards?
You can run a saw blade backwards and it cuts pretty well. However it is not at all a good idea. The two big reasons not to do this is that saw tips are much more likely to come off if the saw blade is run backwards and that the whole saw blade is much more likely to come apart if it is run backwards.
Which way do the teeth face on a circular saw?
The teeth should be cutting UPWARDS, in a clock-wise direction. You’ll also notice that when your blade is installed correctly, the teeth will be pointing upward. Remember: circular saws (as most saws) cut on the upward stroke.
What is a spindle lock?
Most cordless impact drivers have a feature called spindle lock that, when selected, locks the motor’s spindle so the chuck cannot turn. Most models of impact driver will have ‘automatic spindle lock’, which means that the chuck and metal bit are automatically locked when the speed control trigger is released.
How tight should a circular saw blade be?
In general, the blades on right-handed circular saws turn counterclockwise, so you’d tighten the bolt clockwise; the blades on left-handed circular saws turn clockwise, so you’d tighten the bolt counterclockwise.
