A sandblaster is a tool used to clean, smooth, or shape surfaces by propelling abrasive materials, like sand, at high speeds. This process, known as abrasive blasting, is commonly used in industries such as construction, automotive, and manufacturing. Sandblasters can effectively remove rust, paint, and other contaminants from various materials, including metal and wood. There are different types of sandblasters, including pressure blasters and suction blasters, each designed for specific tasks. Safety is crucial when using sandblasters, as the fine particles can be harmful if inhaled. Proper protective gear, such as masks and goggles, is essential to ensure user safety.
