Understanding Grit Size

When I first started using flap wheels, I quickly learned that grit size plays a crucial role in the type of finish I could achieve. A 40 grit flap wheel is relatively coarse, making it ideal for aggressive material removal. It’s perfect for tasks like deburring, stripping paint, and preparing surfaces for further finishing. Knowing this helped me choose the right tool for my specific project needs.
