The portable ___ sander is used frequently for sanding cabinetwork and interior finish.

• A. Belt
• B. Orbital
• C. Disc
• D. Random Orbital

Answer: (A)

For a fine interior finish on cabinetmaking, the goal is a smooth, swirl-free surface with minimal risk of gouging. A belt sander removes material quickly and aggressively, which is great for flattening rough stock but not ideal for finishing delicate cabinet parts; it can leave deep belt lines or gouges that are hard to remove later. A disc sander also tends to leave circular marks and is not the best for broad, flat interior surfaces or curved corners. An orbital sander uses a pad that follows a small circular motion, which is good for finishing, but it can still leave visible swirl patterns if used aggressively or with incompatible grit. A random orbital sander, however, combines random motion with the orbital pattern, so it reduces and virtually eliminates consistent scratching marks. This makes it ideal for cabinet interiors and other finish work where a smooth, even surface is essential and where you’re working on both flat panels and contours. So the best portable sander for sanding cabinetwork and interior finish is the random orbital sander, because it delivers a smooth, finish-ready surface with minimal tool marks.
