Rock Tumbler Kit with Digital Timer, Speed Control and Leak-Proof Barrel

• TURN ROUGH ROCKS INTO POLISHED CREATIONS: This rock tumbler machine recreates the gradual action of natural tumbling to smooth rough stones for display and craft projects. Add suitable rocks, grit, ceramic media and water, secure the barrel, then select the displayed days and speed. Check progress between stages because stone hardness, size and starting condition can affect the finish.
• LOWER-NOISE RUBBER BARREL: The rock polisher uses a tyre-rubber barrel designed to run 75% quieter than plastic barrels, helping soften the harsh rolling sound during multi-day use. A stainless-steel outer cover and double-layer leak-proof lid help contain water and slurry. It will still be audible, so place the unit on a firm, level surface away from quiet living areas.
• DIGITAL CONTROL WITHOUT GUESSWORK: Set the visible day and speed values on this electric rock tumbler kit, switch on Efficient mode when required, and use Pause or Resume to inspect the load without restarting the whole process. Separate displays keep timing and speed easy to read, while the clearly labelled plus and minus controls make adjustments straightforward for first-time users.
• BUILT FOR REPEATABLE TUMBLING: This rotary rock tumbler combines a sturdy base, durable rolling belt and leak-proof drum structure for controlled rotation. The stainless-steel outer cover protects the barrel assembly, while the double-layer lid is designed to close securely. Tighten the lid carefully, keep it facing right during operation, and clean the barrel thoroughly between grit stages.
• FROM STONES TO DIY JEWELLERY: Turn finished stones into necklaces, keyrings, cage pendants, earrings or rings with this rock polishing kit. Rough stones, a strainer, an illustrated learning guide and assorted jewellery findings support the journey from loading the barrel to displaying the finished pieces, creating an engaging project for rock collectors and craft enthusiasts.

Add compatible rocks, the correct polishing grit, ceramic media and water according to the instructions. Do not exceed the confirmed barrel capacity. Refit the double-layer lid and tighten it securely to help prevent leaks. Wipe the outside of the barrel dry before placing it on the machine. Position the barrel with the lid facing right, select the required days and speed, and start the machine. Use Pause and Resume to inspect progress between stages. Empty the barrel through the strainer after each stage, rinse the stones and clean the barrel thoroughly before adding the next grit grade. Important Notes Rock tumbling is a gradual, multi-stage process. Results and processing times vary according to the hardness, size, shape and starting condition of the stones. The machine will remain audible during operation even with its noise-reducing rubber barrel. Place it on a firm, dry and level surface away from quiet living areas, table edges and moisture. Do not pour used polishing slurry down a sink or household drain, as the sediment may settle and cause a blockage. Dispose of it according to local guidance. Check the barrel seal before every cycle. Stop the machine if the barrel leaks, the belt slips, the unit moves from its position or unusual noise occurs.
