Structure of a circular saw
The circular saw is composed of 6 main parts including:
- Case: Made of high quality materials, good electrical insulation, insulation and impact resistance, helping to protect the engine inside well.
- Dust collection system: Blowing dust to ensure hygiene around the work area so that workers can easily observe the surface of the material, cut more accurately.
- Rotational adjustment lock: Allows you to adjust the cutting angle of the saw: 15 degrees, 30 degrees and 45 degrees .
- Saw blade protection cover: Usually made of stainless steel alloy material, it is able to protect the saw blade well, ensuring safety during use.
- Separator: The thickness of the cutter is equivalent to the thickness of the saw blade with a distance 2mm below the highest point of the saw tooth.
- Handle with on/off switch: Allows users to adjust and operate conveniently with just one hand.

The above article introduced you to the circular saw, its structure and operating principle. If you have any questions, leave a comment below!
In conclusion, a circular saw is a versatile and efficient power tool that is widely used in various woodworking and construction projects. It is composed of a circular blade with sharp teeth attached to a motor, which rotates at high speeds to cut through various materials such as wood, metal, and plastic. The structure of a circular saw typically includes a handle, a trigger switch, a guard, and an adjustable base plate.
The working principle of a circular saw is based on the rotation of the blade, which cuts through the material by removing small chips or fragments. When the trigger switch is activated, it powers the motor, causing the blade to spin rapidly. As the blade rotates, the teeth of the blade cut into the material, creating a precise and clean cut. The guard ensures the safety of the user by covering the blade when it is not in use, and the adjustable base plate allows for different cutting angles and depths.
Overall, the circular saw is a fundamental tool in the realm of woodworking and construction, enabling professionals and DIY enthusiasts to achieve accurate and efficient cuts. Its structure and working principle make it an essential tool for a wide range of projects, providing both versatility and precision in cutting various materials.
