Advanced Professional Rock Tumbler Kit 

The Advanced Professional Rock Tumbler Kit, available on Amazon, is comprehensive for hobbyists and educational purposes. Manufactured by Dan&Darci, the kit is designed to transform rough rocks into polished gems, making it an engaging science and STEM project for all ages.

The kit includes a rock tumbler machine with a powerful motor that ensures longevity. The device features a leak-resistant barrel that operates quieter than other brands. It also has advanced features such as speed controls for more granular tumbling results and a digital 9-day timer that automatically shuts off when desired. All these features are displayed on an easy-to-read LCD screen.

The kit has a low-noise barrel with a 1 lb. capacity, four grit packets, half a pound of assorted rough rocks, a mesh strainer, jewelry fasteners, a gem storage bag, and an illustrated instruction and learning guide booklet. However, some users have noted that the amount of grit provided may not be sufficient for optimal polishing results, suggesting the purchase of additional grit.

The rock tumbler has three-speed settings and can be loud, especially at its fastest speed. Some users have found that adding plastic pellets can help reduce the noise. The tumbler’s capacity is smaller, making it ideal for hobby use. Despite its size, it has been praised for its user-friendly design and ease of use.

The kit also includes an illustrated learning booklet with step-by-step instructions and a comprehensive guide on the history of rock tumbling. This makes it an excellent educational tool that fosters a love for science, geology, and mineralogy in a fun and exciting way.

Despite its many strengths, some users have pointed out potential areas for improvement. These include better instructions for cleaning and burnishing and the need for a larger volume for the tumbler. However, overall, the Advanced Professional Rock Tumbler Kit is a well-received product combining education and entertainment, making it a unique gift for children and adults.


The NATIONAL GEOGRAPHIC Rock Tumbler Kit is a unique and well-crafted product for adults and children. The kit includes a rock tumbler with an extra-large 3 lb. capacity barrel, rocks for tumbling, and rock polisher grit. The tumbler stands out due to its three-speed motor and a 9-day timer, which allows users to control the tumbling cycle duration.

One of the key features of this tumbler is its speed. Even at its slowest setting, it operates faster than most other tumblers on the market. This speed, combined with efficient grinding, enables the rocks to hit each other more frequently, resulting in quicker shaping and smoothing. However, this might necessitate cushioning for more fragile gemstones to prevent damage.

The barrel’s design is another distinctive feature. It has a larger diameter but is less profound than other tumblers, allowing for a larger internal volume. This design enables users to put more rocks in each cycle, increasing the grinding efficiency.

The tumbler is robustly built, with a sturdy base that houses the motor and control panel. The barrel has an effective sealing mechanism to prevent leaks, and an extra drive belt is included when the original one wears out. Despite its robust operation, the tumbler produces minimal vibrations and noise, with most of the sound absorbed by the barrel material.

However, the kit does have some limitations. The included rocks mix different types and hardnesses, which may not be ideal for tumbling together. Users may need to order additional stones of a single class for optimal results. Additionally, the included grit and polish packets may not be sufficient for achieving the best results, so purchasing additional supplies from a rock shop is recommended.

Despite these minor drawbacks, Tumbler has received positive reviews for its performance and customer service. One user reported that when their tumbler’s motor failed, the company promptly sent a replacement unit free of charge. The NATIONAL GEOGRAPHIC Rock Tumbler Kit is a high-quality, efficient, and reliable product for rock-tumbling enthusiasts.

Thumler’s Tumbler Rotary Rock Tumbler

Thumler’s Tumbler Rotary Rock Tumbler, model A-r2 #115, is a new and modern rotary tumbler designed for tumbling rocks. This product is extensively used by hobbyists, laboratories, schools, and industries for various tumbling and mixing operations. It effectively polishes gems, stones, coins, brass, and other metals, revealing their hidden natural beauty.

The tumbler comes with two rubber tumbling barrels, each capable of holding up to 6 lbs of rocks. The interior of each barrel measures 4 1/4″ in diameter and 4″ deep (107 x 101 mm). The product also includes an instruction booklet titled “A Guide for Rock Polishers,” providing helpful information for beginners and experts.

The tumbler operates on 110V, 60Hz power and features a fan-cooled motor that is overload protected. Despite its robust functionality, the product has been criticized for quality control issues. These include a blurred ink pad print, a low-quality motor housing with chipped paint, and a motor fan that does not circulate much air. The motor case can get hot, reaching up to 158 degrees Fahrenheit, and there have been complaints about the motor cord wiring being separated beyond the strain relief.

The product lacks rubber feet, which can result in loud vibrations and potential damage to table surfaces over time. However, it has been suggested that installing 4 stick-on rubber cone feet (20mm dia x 22.5mm height) can significantly reduce these issues. Applying a little Tri-Flow Teflon lube to the plastic sleeve bearings can make the unit quieter.

Despite these drawbacks, Thumler’s Rotary Rock Tumbler remains famous for rock tumbling enthusiasts and professionals alike. It is made in the USA, but it is currently unclear when or if this item will be back in stock on Amazon.

Tumble-Bee Rotary Rock Tumbler with Rock Grit Polish Kit

However, the user also noted a few minor issues. The gasket seal in the lid had to be replaced once within the year of use. Additionally, the barrel began to slip and not rotate after several months due to the drive shaft becoming polished. This issue was resolved by roughing up the post with coarse emery cloth.

The user also cautioned against loading the tumbler to its suggested weight limit, which could cause the motor to overheat. Despite these minor setbacks, the user expressed satisfaction with the product’s quality and performance.
