Circular Saw Blade Direction

What is a circular saw blade?

A Circular saw’s blade is a heavy-duty machine that is used for cutting through wood, especially big ones. The machine consists of teeth which role in a particular direction with terrible speed. This speed is what gives it the force to cut through any wood with the sharp teeth.

Mishandling a circular saw blade could lead to an occupational hazard which you must try to avoid. One thing that you must try to always be aware of before you use your circular saw blade is to note if the blades are moving in the right direction.

What is the Circular Saw Blade Direction of Rotation?

As mentioned earlier, this is the most important thing you need to check before you use your circular saw blade. If you trust a circular saw blade may be because you recently just finished using it, then endeavor to check it after you’ve taken it out for repairs.

A normal circular saw blade is supposed to rotate by default. What this means is that, if you recently just purchased yours, you don’t need to worry about the direction of rotation, it will automatically rotate in the right direction.

However, if you just took yours to the repairer and you’re not sure if it is still running in the same direction, then you should try to see if it is running in an anti-clockwise direction. This is the natural and original direction every circular saw blade should be facing.

To ensure that you’re not making a mistake when you collect it from your repairer, don’t start work with it immediately. First of all plug it in, watch it roll. If it is rolling towards the left, then it is ok. If, however, it is rolling towards the right, you might need to turn it off and stay far away from it.

For an extra tip, before you begin to use it after repairs, make sure that you stay far away from it, don’t try to cut any wood with it just yet. If it goes in the opposite direction the blade could run off and that is going to cause some really serious hazard.

Factors that Affect the sharpness of the circular saw blade:

There is a chance that after a few months or years, depending on how often you use your circular saw blade, it would get blunt or it could even get rusty. During this period, you will need to change it so that you can become more productive and effective when you work.

The question becomes, how do you change a circular saw blade? But before we get into the process of changing your circular saw blade, what do you think are the factors that affect the sharpness of your circular saw blade?

a) Frequency of use:

The more frequently you use your circular saw blade, the more it gets blunt. For some people, they use it just once or twice a month. For others, they use it every day for all the 30 days in the month.

Now you can’t expect your circular saw blade to stay as sharp as the one that gets used only once in a while when actually you use yours every day. That is going to affect the sharpness of the circular saw blade. You will need to frequently sharpen it to make it more effective for use. She cannot go through the process of sharpening it, then you can at least clean it up using the cleaning chemical.

b) The material you cut with it:

just like with the frequency of use, some people use their circular saw blade every day but only for cutting slim pieces of wood. When you compare this to the person who cuts heavy wood, you will see that 1 circular saw blade is working far harder than the other. The thicker the wood the blunter it makes your circular saw blade.

This is not to say that if you stop cutting your heavy wood with the circular saw blade, it is just a reminder that cutting heavy wood could greatly affect the sharpness of your circular saw blade

c) The quality of your blade:

if you’re using a circular saw blade and the blade in the machine isn’t strong enough to stand hard work like cutting through a thick wood, then you might need to get a new one.

Usually, most of the circular saw blades come with quality blades. The problem comes when you change the blade that came with it probably because it has become old. You should ask your repairer to get you a blade that won’t make you stress with your work.

b) The machine begins to make too much noise:

sometimes this might happen due to other reasons but majorly it is because the machine has begun to work too much. One of the most telling reasons for this is because the blades aren’t making the job easy.

c) You will find it difficult to maintain a straight line:
