Thinking Outside the Box: Can You Put Two Blades On A Circular Saw?

A circular saw might be the most complex construction tool you have ever used. It is indeed handy, but it comes with so many variations and traits that it may seem like a rocket science class to comprehend all that.

A circular saw comes with a specific blade that it can attach to the spindle. You can’t put two separate blades on a circular saw. But you can use a dual-blade circular saw instead.

If you are not familiar with the idea of dual blades, dig into this article to find out more.

Can You Put Two Blades On A Circular Saw

Putting Two Blades On A Circular Saw

The prominent part and the focal purpose of a circular saw is certainly its blade. This might give you the thought that the more blade you can put in, the more powerful your circular saw becomes. But is it really how this works?

The number of blades you insert inside a circular saw has no contribution to its power and strength. To tell the truth, you can’t even put two blades in a single circular blade as the spindle that holds the blade has a certain tightness and tension that would be defiled when you attempt to put two or more blades inside them.

So, putting two blades on a circular saw is not only unsafe and perilous but also impossible to accomplish. You have to use the specific blade specified for the particular circular saw. However, if you want to some arrangements that could cut both front and back at the same go, I think I have something for you.

Dual-Blade Circular Saw

A dual-blade circular saw is a new concept of the blade where two opposite rotating blades at the same speed are smooshed together. These special blades are used mostly to make straight plunge cuts. Double-rotating blades increase the stability and deter the deformation of the material.

Counter-rotating blade circular saw is a powerful and convenient tool, but it is very advanced as well. You will get a thoroughly clean cut even in difficult plunge cuts if you can adapt its usage.

Smooth Edgy Cuts

Often with a regular circular saw, the cuts are very rough and coarse. You have to manually smooth the cut edge after the operation. However, as the blades of a dual-blade circular saw rotate in a synchronizing way, the cuts are clearer and smoother. The forwarding blade makes the cut, and the backward blade makes the cut more edgy and smooth.

Minimal Kickbacks

When the blades beget to propel over the cutline, you will certainly feel resistance from the circular saw. In layman’s terms, this situation is known as kickbacks. A regular blade has more control over the saw and the user as it propels upwards and downwards while cutting. Meanwhile, as the blades are canceling each other’s kickbacks, you won’t feel that while using.

Size And Style

The blades of the dual-blade circular saw are slightly smaller than a regular circular saw blade. Most models you will find has a 4 and a half inch blade. Not only the blade but the body of a dual-blade circular saw is compact in size too. They are suitable for one-hand operation. Due to their weight and style, this circular saw blade will not slip.

More Control Over The Saw

A regular circular saw has a tension between the user’s pressure and the blade’s movement. That is why a novice often loses control and lets the blade move the saw. However, the tension in a dual-blade circular saw is between two contrasting and opposite rotating blades. This tension acts to your benefit, giving you more control over the saw.

Wax For The Dual-Blade Circular Saw

As the double blades are frequently contrasting and thrusting upon each other, there should be enough lube to function properly. The material the blade is cutting welds to the tooth of the blades. After regular use, the sharpness of the tool is abridged. The wax will prevent the tooth from decaying and the blades from clashing while cutting metal like aluminum and copper.

Blades Are Not Easily Obtainable

The dual-blade circular saws are rarely available in your local markets. Even if you can obtain a saw for yourself, it will take a great toil to fetch more blades suitable to replace the blades of the circular saw. It is very expensive too. Also, you will need the exact type of blade for a particular model of the saw. There is no chance to use a different blade for different dual-blade saws.

Plunge Cuts

A plunge cut is a difficult cut to master with a regular circular saw. Since there is no starting point where you can start your cutline, you need to be careful not to damage the material and make a hole where you want it to be. Since a dual-blade saw gives you more control and reduces the kickback, you can make difficult cuts like plunge and others.

Materials

Double-bladed circular saws are super-efficient for cutting through the metals without changing the blades for each metal. Aluminum, copper, iron, tin, stainless steel, and rebar can be cut precisely with the help of a dual-blade circular saw.

You can cut fine materials such as wood and veneer only when they are in a pinch. If you are looking for a handy dual-blade circular blade, consider 9TRADING Dual Blades.

Some Tips To Remember

  • Before purchasing a circular saw, always make sure the amp power is compatible with the power socket in your workshop. The most dual-blade circular saw comes with 4 amps.
  • Make sure the blades on the circular saw are carbide tipped. As the friction between two blades would create excessive heat and tension, the carbide blades will help to tone down the friction.
  • Always check whether the blades have enough wax between and on the tip of the blades before starting to cut the material. A well-lubricated saw will make the efficiency twofold.
  • If you want to purchase a dual-blade circular saw, opt for the cordless version of it. It will be more resourceful and handier to use.

FAQ

Can I put a bigger size blade on a circular saw?

Every circular saw comes with a specified blade size that is compatible with the tool. You can replace the blade when it becomes weary, but you can’t exchange it for a bigger or smaller blade size. Attaching a larger blade will put the material and the circular saw at risk.

If you put a larger-sized blade on your circular saw, the teeth of the blade will not be able to provide the required clearance, and the guard over the blade might be hit by the oversized blade. If you must use a larger blade, make sure it only exceeds half an inch from the original blade size.

How many blades can you put in a circular saw?

You can only put the exact number of blades the circular saw prescribes you to. If the saw can accommodate only one blade, you can’t put two or more blades on them. This is not only a hazard but an impossible task.

The spindle that holds the blade in its position has a particular girth. It can’t be expanded or reduced. And if the blade is not securely fixed with the spindle, the blade will either slip or stop rotating altogether. So, for a regular circular saw, only one blade can be installed.

When should I replace the blade with a circular saw?

Depending on the model’s quality and condition, a circular saw blade can run for 12 -120 hours altogether. After that, the tooth of the blade will beget to decay and wear out. This is an indication to change the blades and replace them with newer and sharper blades.

The first sign of decay can be found in the carbide edges. It might not be visible to the bare eyes initially, but you can certainly see the decay under a bright light or magnifying glass. Also, the cut on the material will be blunter and rough too.

Final Words

A circular saw is a very stubborn and fixated tool that doesn’t cooperate nicely with changes. If the circular saw is made to accommodate one single blade, you can’t push more than one blade on them. However, now you can avail of these futuristic dual-blade circular saws that have enjoined two blades rotating in opposite directions.
