Uses of a Circular Saw 

Here are the seven uses of a circular saw


Initially, mills used small to medium circular saws to cut across those huge timber blocks. The first generation of circular saws was constructive for Laths. Although, in today’s date, sawmills have started preferring larger circular saws that usually measure up to three meters to cut the timbers of the forest into a more reasonable size. 


One of the most used and famous types of the circular saw is a col saw used to cut down the metals such as brass, bronze, and steel into a more convenient and smaller size. The saw’s larger diameter contains sharp teeth that help the manufacturers cut the metals down with absolute precision. It also helps in cutting the metals down horizontally into lean slots for fabrication.


A few days ago, the Americans in rural areas used a circular saw named ‘cordwood saw’ to cut slabs and logs. They cut those slabs and logs, and with the help of cordwood circular saws, they turn them into firewood. These days the manufacturers of industrial firewood choose circular saws instead of chainsaws (traditional) because cordwood possesses better performance and a prolonged lifetime.


If you want to have 90 degrees of straight cuts, the circular saw is the best out there. The circular saw is for cutting the boards, lumber, and metals into different kinds of angles. Although, for smooth and better cuts, use a high numbered teeth blade. Otherwise, just use the blade, which has fewer teeth for abrasive and fast cuts.


The cross cuts have proved to be the best way to shorten the length of longboards and limber. It cuts the wood in the direction of the grain so that the quality of grain remains high throughout when a carpenter is doing a traditional cross-cut. One of the best ways to get done the cross-cut quickly is the usage of a circular saw. 


By bevels, it means a horizontal or a vertical slope to attach the separate block with extra power. A circular saw has proved to be the best tool for the creation of bevels at 45 degrees. Though the circular saws do not give you perfection in the slopes, it is for substantial infrastructural and construction worksites. 


Most of the woodwork requires thin and long plywood. A circular saw used with a few techniques can easily do the job of cutting those long plywood even better than most saws out there.  Power saw experts have confirmed that the cutting of plywood with the help of circular saws is more manageable than other substitutes and techniques. 

Types of Circular Saws 

Here are the two types of circular saws:

  • Worm drive circular saw
  • Sidewinder circular saw

The worm drive circular saws come with the motor in its blade. It transfers the rotation power of its engine to the blade through the set of gears. A worm drive circular saw has both advantages and disadvantages. It reduces the blade’s speed, reaching the maximum speed of 4500 RPM, whereas it expands the torque.

Mostly all of the worm drive circular saws have the blade on their left side. Plus, it has a bit of a heavier weight as compared to a sidewinder saw. Also, its shoe is a bit thicker. 

The sidewinder circular has a motor which is known as “a spur gear.” Its inline blade with the motor produces stronger power to the blade, almost up to 6000 RPM. The sidewinder circular saw also has a blade on its right side.

Safety Precautions While Using Circular Saws 

A circular saw is a dangerous and powerful tool, so the users must take full safety precautions to carry out careful and safe work. So, before using the circular saw, make sure to wear all the safety gear and equipment. 

Here’s a checklist

  • You must check the stability of the workbench or the sawhorse.
  • Make sure that the blade is perfectly fixed. 
  • Make sure to hold the saw tightly with both of your hands. 
  • Start making your cuts only when the circular saw reaches its highest speed.
  • Keep the power cords far from the cutting area.
