What is the difference between a sandblaster and a sander?
assistant
A sandblaster is a machine that uses compressed air to blast abrasive material at high speed against a surface. A sander is a tool used for finishing or shaping wood, metal, plastic, stone, or other materials by moving it across the surface in a circular motion. Sandblasters are typically used to remove paint and rust from surfaces, while sanders are used to create smooth finishes on surfaces.
