A saw is a tool that uses a blade or a chain with teeth to cut through materials such as wood, metal, or plastic. Among the various types of saws, the rotary saw and the circular saw are two of the most popular ones used in different industries and applications. Although they share a lot of similarities, they have distinct differences that set them apart from each other. In this article, we will delve deeper into the differences between a rotary saw and a circular saw.
Overview of Rotary Saw and Circular Saw
A rotary saw is a handheld power tool that uses a rotating blade to cut through various materials such as metal, plastic, and wood. It is also referred to as a cut-off saw, angle grinder, or disc cutter. The blade of a rotary saw is typically made of abrasive material or high-speed steel, which can withstand high temperatures.
On the other hand, a circular saw is a power tool that uses a circular blade with teeth to cut through materials. It is also called a skill saw or buzz saw. A circular saw is commonly used in woodworking applications to make straight cuts, crosscuts, and rip cuts.
Blade Size and Type
One of the primary differences between a rotary saw and a circular saw is their blade size and type. A rotary saw typically has a smaller blade size, ranging from 4 to 12 inches in diameter. The blades of a rotary saw are often made of abrasive material or diamond, which makes them ideal for cutting through hard and tough materials such as metal and masonry.
In contrast, a circular saw has a larger blade size, ranging from 7 1/4 to 16 inches in diameter. The blades of a circular saw are made of different materials such as high-speed steel, carbide, and diamond. The type of blade used in a circular saw depends on the application and material being cut.
Cutting Depth
Another significant difference between a rotary saw and a circular saw is their cutting depth. A rotary saw has a shallow cutting depth, typically ranging from 1 to 3 inches. It is suitable for making precise cuts in small and tight spaces, such as cutting through pipes, tiles, and concrete blocks.
In contrast, a circular saw has a deeper cutting depth, ranging from 2 to 4 inches. It is ideal for making long and straight cuts in thicker materials such as lumber, plywood, and engineered wood.
Application
The application of a rotary saw and a circular saw also differs from each other. A rotary saw is commonly used in construction, metalworking, and masonry to cut through hard and tough materials such as steel, concrete, and brick. It is also used in automotive repair and maintenance to cut through metal parts.
A circular saw, on the other hand, is commonly used in woodworking and carpentry applications to make straight and angled cuts in various types of wood. It is also used in construction to cut through lumber, plywood, and other engineered wood products.
Safety
When it comes to safety, both rotary saws and circular saws require caution and proper handling to prevent accidents and injuries. A rotary saw can generate a lot of dust and debris when cutting through materials, which can cause respiratory issues if inhaled. It is essential to wear a dust mask and safety goggles while using a rotary saw.
Similarly, a circular saw can cause kickback and other hazards if not used properly. It is crucial to follow the safety guidelines and use safety equipment such as safety glasses, ear protection, and dust masks while using a circular saw.
Conclusion
In conclusion, a rotary saw and a circular saw are two different types of saws that are used in various industries and applications. While they share some similarities in terms of cutting, they differ significantly in terms of blade size and type, cutting depth, application, and safety. Choosing the right saw for your project depends on the material being cut, the application, and the level of precision required. By understanding the differences between the two saws, you can make an informed decision and ensure the success of your project.

Frequently Asked Questions
1. What is a rotary saw?
A rotary saw is a type of power saw that uses a spinning blade to make cuts. It is often used for cutting through tough materials like metal or concrete.
2. What is a circular saw?
A circular saw is also a type of power saw that uses a circular blade to make cuts. It is commonly used for cutting through wood and other softer materials.
3. What is the main difference between a rotary saw and a circular saw?
The main difference between a rotary saw and a circular saw is the type of blade that they use. Rotary saws use abrasive blades that can cut through tough materials, while circular saws use toothed blades that are better suited for cutting through softer materials like wood.
