Circular Saw Blade Direction

Circular Saw Blade Direction

Have you ever used a circular saw whose blade faces the opposite direction? How was the experience? Did you face any challenges?

Well, these and many others are the questions that could be lingering in your mind.

Many circular saws have an arrow that is printed on the blade. It is indicative of the direction with which you should install the saw. You should, therefore, place the blade in the direction of the arrow. What, then, would you do if your machine lacks this indicator? In this article, we are going to look at the step by step procedure of carrying out the installation. Please read on for more information.

Which direction should the teeth point?

There are several types of saws. The direction of the teeth can be different for each set. A circular saw, for example, should have its teeth facing to the front. However, much depends on the type of the saw that you have. Do not forget to check on the arrows because they are the accurate guide to installation.

Not all models have the blade facing the front. There are some with their teeth facing downwards, though they are not common.

Can you put the blades facing backwards?

Yes you can put it facing back, though it is not a common phenomenon to many users. The idea is also for specific duties such as cutting vinyl. In such a case, you have to install a fine-toothed blade facing backwards.

You have to be careful when having the blade in such a condition, since it may pull an object within a split second!

It is advisable to have the blade facing backwards?

On routine duties, it is not advisable to do so. However, if you have any specific duty that would require you to place it otherwise, then you should proceed with the same! It is not harmful as it sounds, but it can be disastrous when it comes into contact with other objects.

Which way does the blade go?

It cuts on the upward stroke. The implication is that they rotate in clockwise direction. The movement is bottom-up direction. To correspond, the side of the wood that you are cutting will be facing down.

What about the teeth?

They should correspond with the general direction of the blade. In most cases, the arrow on the baled will also indicate the direction of the teeth.

Does the number of thee of the circular blade matter?

Yes they do. The more the number of teeth a blade has, the faster it would be. More of them will also determine the type and the finish of the cut.

The general rule, therefore, is that you should always use one with more teeth if you want a quality output. I cannot rule out the usefulness and strength of a blade with fewer teeth. It performs the same quantity of job only that many teeth is for precision cuts and smoothening.

Why does it produce a lot of heat when in use?

If it is a dull one, then it will not be possible to cut through the product properly. It will lead to the generation of friction against the product. If you push on your circular saw at this moment, then it will generate a lot of heat instead. It leads to the reduction of the useful life of your tool.

In some cases, the blade will be affected by dirt, and hence make it appear like it does not cut well. To avoid this, clean your circular saw blade frequently, and especially when it is not in use!

Which way should it spin?

By default, the blade of this kind of a saw rotates in anti-clockwise (counter-clockwise) direction. It should cut in an upstroke and forward direction. When it rotates, the impact pushes the material towards the blade. It helps to maintain the stability of the saw even when the work is intense!

Can you replace the circular saw blade?

Yes, they are replaceable. All types of tools undergo wear and tear. The rate at which it depreciates will depend on the type of work and the frequency of usage.

The Procedure of replacement.

  • Disconnect it from the power source if it is connected by a cord. If it is cordless, then remove the batteries.
  • Push down the arbor-block button on the saw until it engages the locking mechanism.
  • Remove he arbor nut that is holding the blade in place. Turn the wrench in similar direction to that of the blade to loosen the nut.
  • Remove the guard and take off the old blade from the saw.
  • Place the new one onto the arbor. Please make sure that the teeth face the direction of the rotation. If in doubt, always check on the direction of the arrow in the guard.
  • Tighten the arbor nut using the blade wrench. Turn it until it snags. Do not overtighten because but will be difficult to unscrew the next time you would want to change the blade!
  • Test the saw. Try cutting a piece of wood and assess its suitability based on the work that it does.

How long does it take before replacing the blade?

It depends with the intensity of how you engage it. The more you use it, the much it wears out fast. If you also engage it when it is blunt, it will generate a lot of friction which in turn will eat out the blade’s teeth within a short time!

Can you sharpen the blade’s saw?

Yes you do not need to change it every time it goes blunt. Instead, you can sharpen it and continue with your duties. It is not costly to sharpen it, and you should do it as often as it requires.

How much does it cost to replace the circular saw blade?

Many factors come into play in determining the cost of replacement. However, on average, it costs between twelve and eighteen dollars for a seven-and –a-quarter inch circular saw blade. Other factors such the cost of the blade and the taxes involved there in also plays a role in determining the cost!

Conclusion

Determining the direction which the teeth of a circular saw should face is a critical factor. Luckily, the arrow on the blade’s guard is indicative of the direction. If you place it wrongly, then it may cause some damages to the system. Always make sure that you do it the right way.

In over 6 years I have tried several wood working tools including circular saws, table saws, chain saws, and jigsaw among the rest. My inspiration came from watching my dada work. I also learned that many people didn’t quite understand how to use these tools. Today, I have helped so many people to learn the use, benefits, and how these DIY woodworking tools operate. I have created a number of work-tools related posts, built websites, and developed social media pages. Follow me here to learn more.
