For a smoother finish, always choose foam orbital sander pads. Rubber orbital sanders are better for heavy-duty sanding tasks. The type of orbital pads you choose will depend on your surface, desired finish, and comfort level. In this article, we will discuss the difference between foam vs rubber orbital sander pads and how choose the right orbital sander pad for your project.
What Are Foam Orbital Sander Pads?
Foam sander pads will help you achieve a smooth, even finish on a variety of surfaces. They can be used for auto body work, woodworking, or home repairs. Foam pads are commonly used as orbital sander pads for car paint because they help to avoid deep scratches.
How Foam Orbital Sander Pads Work
The foam layer is placed between the orbital sander and sandpaper when you attach a pad of foam to it. As you press down, the foam will compress. The pad will follow the contours of the surface. This allows you to sand flat surfaces, curves, and edges without the risk of gouging. Foam absorbs vibrations, allowing your hands to feel less fatigued during long sanding tasks.
Use foam pads to achieve a smooth, fine finish on painted or wood surfaces.
Pros of Foam Orbital Sander Pads
Foam pads are a great choice for sanders.
- The result is a finish that is smooth and free of swirls.
- The adaptability of the swivels to uneven surfaces and curves is remarkable.
- By absorbing vibration, they reduce fatigue.

- If you catch the edge or press too hard, they can tear.
You may want to use a different pad if you have to remove a large amount of material or smooth rough surfaces.
What Are Rubber Orbital Sander Pads?
Rubber orbital sanders provide a stable and strong base for sanding. Use them to remove large amounts of material, or when working on rough surfaces. Rubber pads are often chosen as orbital sander pads for metal polishing when consistent pressure and durability are required. The pads are made with a thick layer of rubber that holds the sandpaper firmly and flat. This design allows you to maintain control and achieve even results on even the toughest jobs.
How Rubber Orbital Sander Pads Work
The rubber layer is placed between the tool and sandpaper when you attach a pad to a sander. Rubber does not compress very much. The pad will remain flat and rigid while you sand. Rubber pads are resistant to tearing or bending, so you can press harder without fear of damaging them. Rubber pads are a great choice for heavy-duty sanding and leveling uneven surfaces.
Rubber pads are ideal for removing paint, sanding rough wood, or removing rust from metal.
Pros of Rubber Orbital Sander Pads
Rubber pads are a great option for orbital sanders.
- These pads last much longer than foam.
- These machines are able to handle rough surfaces and tough jobs.
- You can sand more evenly with them.
- The material is resistant to tearing and damage.
Rubber pads are often preferred as long-lasting orbital sander pads for extended or demanding sanding projects.
Here are the main benefits.
| Benefit | Description |
| Durability | Stands up to heavy use |
| Control | Keeps sandpaper flat and steady |
| Versatility | Works on wood, metal, and paint |
Cons of Rubber Orbital Sander Pads
Rubber pads have their own downsides.
- The curves and detailed shapes are not well-suited to them.
- If you press on them too hard, they can leave marks.
- Because they don’t absorb vibration, they may cause hand fatigue.
Choose a different pad if you are sanding a delicate or curved surface.
