A sander is a tool used to smooth or shape wood, metal, or other materials. There are several types of sanders available, each with a specific purpose and level of aggressiveness. Two of the most commonly used sanders are the belt sander and the orbital sander.
The purpose of this blog is to compare and contrast the belt sander and the orbital sander and to determine which one is more aggressive.
Sanding is an important part of many woodworking and metalworking projects, and choosing the right sander for the job is essential for achieving the desired results.
This blog will provide information on the differences between the two types of sanders and help readers determine which one is best for their particular project.
Belt sanders are known for their speed and power, making them a popular choice for heavy-duty sanding tasks such as removing paint or roughing up surfaces.
On the other hand, orbital sanders are designed for lighter sanding tasks, such as smoothing out surfaces and are considered less aggressive than belt sanders.
This is due to the orbital sander’s circular sanding action, which is less likely to cause deep scratches or gouges in the surface being sanded.
