What happens here

In contrast to direct drive, the 5-inch and 6-inch sanders are presented as random orbital types. This mechanism combines two movements: the sanding pad rotates on its axis and simultaneously moves in an eccentric orbit. This dual action creates a non-repeating, random sanding pattern that effectively minimizes visible swirl marks and allows for a much wider sanding swath, making it highly efficient for covering larger surfaces and achieving a smoother, more uniform finish in DIY projects.

Goal: Grasp the dual-action mechanism and benefits of a random orbital sander for broad DIY applications.

What they say

Hide

Okay, and I notice all of them, they're variable speed, and you can adjust them, there's a plus and a minus, and they're simple to adjust, are they random orbit or direct-drive sanders? The 3-Bot 4 is a direct drive, so that means it's orbiting, but it's orbiting in a circle. No random pattern. These two are random argo, the 5-inch and the 6-inch are random argo, so you have a much wider swath and you have that rotation and that random pattern. Alright?
