What happens here

The discussion then shifts to the types of orbital action. A 3x4 sander is identified as a 'direct drive' sander, meaning its sanding pad orbits in a consistent circular pattern without any random movement. In contrast, the 5-inch and 6-inch sanders are described as 'random orbital' tools. This indicates that their pads combine a circular motion with an eccentric, random orbit, which results in a much wider sanding swath and helps prevent swirl marks on the sanded surface.

Goal: Grasp the difference between direct drive and random orbital sanding mechanisms.

What they say

Hide

Are they random orbit or direct-rive sanders? The 3.4 is a direct drive, so that means it's orbiting, but it's orbiting in a circle. Pardon? No random pattern. Pardon? These two are random or will the 5-inch and the 6-inch are random or will, so you have a much wider swath than you have that rotation and that random pattern.
