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 edge in the direction of the arrow.
What, then, would you do if your machine lacked this indicator? This article will 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 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. Some with their teeth facing downwards, though they are not common.
Can you put the blades facing backward?
Yes, you can put it facing back, though it is unfamiliar 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 backward.
You have to be careful when having the blade in such a condition since it may pull an object within a split second!
Is it advisable to have the blade facing backward?
On routine duties, it is not advisable to do so. However, if you have any specific task 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 a clockwise direction. The movement is bottom-up direction. The side of the wood you are cutting will be facing down to correspond.
What about the teeth?
They should correspond with the general direction of the blade. In most cases, the arrow on the blade 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. Therefore, the general rule is that you should always use one with more teeth if you want a quality output.
I cannot rule out the usefulness and strength with fewer teeth. It performs the same quantity of job only that many teeth are for precision cuts and smoothening.
Why does it produce a lot of heat when in use?
If it is dull, it will not be possible to cut through the product correctly. It will lead to the generation of friction against the product.
If you push on your circular saw at this moment, 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, making it appear like it does not cut well. To avoid this, clean your circular saw blade frequently, especially when not in use!
Which way should it spin?
By default, the blade of this kind of saw rotates in an anti-clockwise (counter-clockwise) direction. Therefore, it should cut in an upstroke and forward advice.
When it rotates, the impact pushes the material towards the blade. It helps to maintain the saw’s stability 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 kind of work and the frequency of usage.
The Procedure of replacement.
- Disconnect it from the power source if a cord connects it. If it is cordless, then remove the batteries.
- Push down the arbor-block button on the saw until it engages the locking mechanism.
- Remove the arbor nut that is holding the blade in place. Turn the wrench in a similar direction to the blade’s 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 want to change the blade!
- Test the saw. Try cutting a piece of wood and assessing its suitability based on its work.
How long does it take before replacing the blade?
It depends on 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 will quickly eat out the blade’s teeth!
Can you sharpen the blade’s saw?
Yes, you do not need to change it whenever 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 as the cost of the blade and the taxes involved therein also play a role in determining the cost!
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 order.
If you place it wrongly, then it may cause some damage to the system. So always make sure that you do it the right way.
