Understanding 4 Inch Grinding Discs

When I first started using grinding discs, I was amazed at how versatile they could be. 4 inch grinding discs are typically used with angle grinders and are ideal for various tasks, including cutting, grinding, and polishing different materials. Knowing their purpose helps me choose the right disc for my projects.

Types of Grinding Discs

As I explored different types of grinding discs, I learned that they come in various materials and designs. The most common types include metal grinding discs, diamond grinding discs, and flap discs. Each type has its strengths, depending on the material I’m working with. For example, diamond discs excel on hard surfaces, while flap discs offer a smoother finish.
