Rotary tumblers are generally straightforward to load, require minimal supervision, and deliver excellent results for most stones and metals. They effectively smooth out sharp edges and points, leaving stones with rounded surfaces and contours. However, rotary tumblers are not ideal for preformed materials where maintaining specific shapes is desired.
