Can You Use an Angle Grinder as a Sander? A Practical Guide
If you're on a budget, you might wonder: Can my angle grinder double as a sander? The short answer is yes, but with major limitations. Let's break down when it works, when it doesn't, and what alternatives you should consider.
Why an Angle Grinder Isn't Ideal for Sanding
Angle grinders are powerful, high-speed tools (often running at 10,000+ RPM), making them great for cutting and grinding but too aggressive for most sanding jobs. Here's why:
- Circular Scratches & Gouges - Even with fine-grit sanding discs, the fast rotation leaves visible marks.
- No Orbital Motion - Unlike sanders, grinders don't move in a random orbit, leading to uneven finishes.
- Heat Buildup - The high speed can burn wood, plastic, or fiberglass in seconds.
- Limited Control - Most grinders lack variable speed, making them too harsh for delicate work.
When Can You Use a Grinder for Sanding?
- Rough Work - Removing rust, paint, or heavy material.
- Flap Discs - These can smooth metal or hard surfaces but still require caution.
- Heavy-Duty Shaping - Carving wood or aggressive material removal.
What Should You Use Instead?
For smoother finishes, especially on wood, fiberglass, or painted surfaces, a dedicated orbital sander is the best choice. It offers:
- Controlled speed (avoiding burns and gouges)
- Random orbital motion (preventing swirl marks)
- Better dust management (important for health and visibility)
