Final answer:
Random Orbit sanders are designed to produce a smooth finish on surfaces without leaving scratches, although they do generate dust that can be managed with dust collection systems.
Step-by-step explanation:
A random orbital sander (also known as a palm sander) is a hand-held power tool which sands in a random-orbit action. That is, in constant irregular overlapping circles. This technology was first commercially utilized in 1968 by Rupes Tools. Random orbital sanders can make short work of drywall sanding.
However, it's important to attach a vacuum or a dust bag at the minimum, as compound dust is very fine and will get everywhere if given the chance. A wet/dry vac is the best option. Random Orbit sanders are power tools used in woodworking and auto body work, known for their sanding efficiency and ability to produce a smooth finish on surfaces without leaving noticeable swirl marks or scratches.
When used properly, they oscillate in random patterns, which helps to avoid repetitive scratches that can occur with other sanders. They do, however, create dust, which is typically managed with built-in dust collection systems or by connecting the sander to a shop vacuum. To achieve the best results, it's important to select the appropriate grit sandpaper and to apply consistent pressure throughout the sanding process.
