Sander vs Grinder: What’s the Difference?

If you work with wood, metal, or even plastic, the sander vs. grinder question might have stumped you. Belt sanders and belt grinders look similar, but they’re designed for different jobs. Choosing the right one is key for both woodworking and metalworking!

What’s a Belt Sander?

  • Think of it like a power file for sanding wood! It uses a loop of sandpaper (a belt) to smooth, shape, and clean up materials.
  • Belt sanders excel at woodworking, some plastics, and even removing old finishes and fixing tools. Their belts move slower, and they have one main sanding area – a flat piece called a platen.

What’s a Belt Grinder?

  • This metalworking powerhouse has tough, fast-spinning belts for serious grinding, sharpening tools, and shaping metal.
  • The coolest part? Belt grinders give you options. Use the flat part (platen) or a curved part (contact wheel) for different shapes and finishes – perfect for sharpening tools and metalworking projects.
