Right Angle Sanders

This type of sander is the most powerful of the three. It is built with very powerful motors and is recommended for heavy-duty tasks. You can use the right-angle sanders for large surfaces like fiberglass boats, tabletops, and auto-body panels.

However, it is not as powerful as the right angle sander; instead, it is easier to control. You can use it for a variety of projects because it is versatile, and it is especially great for fine sanding furniture.
