The Extreme Rebel 17 stands as a formidable contender in the premium rock tumbler market, earning its second-place position through exceptional build quality and professional-grade results. Its impressive 17-pound capacity stainless steel hexagon drum represents a significant advantage for serious collectors looking to process larger batches of material efficiently.
What truly distinguishes this model is its fan-cooled motor specifically engineered for rock tumbling applications, allowing for extended operation without the overheating issues that plague many competitive models. The optimized low-speed operation at 20 RPM strikes an ideal balance between effective tumbling action and gentle stone handling that preserves delicate specimens while still achieving excellent polish.
The powder-coated finish and precision engineering demonstrate attention to durability concerns, addressing the common frustration of tumblers that fail after minimal use. Enthusiasts who have invested in quality stones will appreciate how the removable rubber liner protects both the equipment and materials during the extended tumbling process required for professional results.
While slightly louder than our top pick, the Extreme Rebel 17 still operates at a reasonable noise level that won’t disturb household activities when placed in an appropriate location. The three-year warranty on the unit and one-year warranty on the motor provide valuable peace of mind for what represents a significant investment in your lapidary pursuits.
The Thumler’s Rock Tumbler has earned its reputation as a reliable workhorse in the lapidary community, offering a proven design that has stood the test of time. With its generous 12-pound capacity hexagonal rubber barrel, this model provides sufficient volume for serious hobbyists while maintaining a more manageable footprint than larger industrial options.
The continuous duty motor featuring built-in overload protection represents a significant advantage for those engaging in extended tumbling cycles. This thoughtful engineering prevents damage during power fluctuations and allows for the multi-week processing times often required to achieve professional-quality finishes on harder stone varieties.
The dual-purpose functionality offers impressive versatility, functioning equally well as a dedicated rock tumbler or as a case polisher for handloaded ammunition. This flexibility provides excellent value for those with multiple hobbies requiring similar tumbling action without compromising performance in either application.
While not incorporating the latest noise reduction technology found in newer models, Thumler’s still delivers reasonably quiet operation compared to budget options. The fan-cooled design ensures consistent performance during extended operation, addressing the common frustration of equipment that overheats and shuts down mid-cycle.
