Quiet direct-drive rock tumbler

This rock tumbler kit uses a low-voltage direct-drive motor that runs at 35 dB, removing the need for belt maintenance while polishing stones. It suits hobbyists and families who want a compact, low-noise machine for turning rough rocks into finished gems.

9-day timer with four speed steps

A 1- to 9-day timer and four speed levels from 75 RPM to 120 RPM let you match cycle length and intensity to each polishing stage. Overload protection and power-off memory automatically resume the remaining cycle after an outage.

Rough stones, grits and jewellery findings included

The box supplies 450 g of mixed rough stones, 200 g of round abrasive media, and four silicon-carbide grits at 320#, 600# and 800# plus polishing powder. A strainer spoon, shaker ball, jump ring, pendant cord and ring blank with flat pad let you turn polished stones into wearable pieces straight away.

Questions about this item

How do I install the barrel on the direct-drive motor without a belt?

Place the barrel on the motor shaft, align the drive lugs, and secure the retaining nut by hand; the direct-drive design removes any belt tension step.

Which consumables will need replacement after the supplied grits are used?

The kit includes 30 g each of 320#, 600#, 800# silicon carbide grit and polishing powder plus 200 g abrasive media; all are single-use and must be replenished for future batches.

What is the first limit reached during a continuous 9-day cycle at 120 RPM?

The 9-day timer is the hard stop; the motor runs at 35 dB with overload protection, so the timer expires before thermal or mechanical limits appear.
