K2 Ultra Quiet Rock Tumbler Kit - 3LB Professional Rock Polisher | Quiet Brushless Motor, Up to 6X Noise Reduction

Key features

• Ultra Quiet Performance for Home Tumbling — The K2 Quiet Elite runs up to 6X quieter than standard rock tumblers. A dedicated noise-reduction cover seals around the barrel to contain vibration, while soft rubber barrel walls cut tumbling noise by up to 75% vs. plastic barrels. Run it in an apartment, a shared workspace, or overnight without disturbing — ideal for families, beginners, and hobbyists who value a peaceful environment.
• Covered Barrel Design for Family-Safe Operation — The noise-reduction cover does double duty: it contains noise AND acts as a protective barrier that prevents children from touching the rotating barrel during operation. This makes the K2 Quiet Elite safe for family use with children ages 8 and up — parents can run tumbling cycles with peace of mind, knowing little hands stay clear. Perfect for family science projects, STEM learning activities, and introducing kids to geology in a safe, controlled way.
• Premium Brushless Motor for Long-Lasting Performance — The K2 Quiet Elite runs on a brushless motor designed for smoother barrel rotation, lower heat output, and significantly reduced wear compared to brushed alternatives. No brushes means fewer moving parts to replace, a longer service life, and more consistent torque across every polishing stage — so stones polish evenly from the first batch to the hundredth. Whether it's your first rock tumbler or an upgrade from a basic model, the brushless drive system ensures reliable performance for years to come.
• 3LB Capacity for Every Skill Level — The K2 Quiet Elite's 3LB rubber barrel gives you 50% more capacity than 2LB entry-level models — more stones per cycle means fewer batches and more time enjoying finished results. Handles agates, jasper, quartz, river rocks, crystals, and most popular tumbling stones. The soft rubber walls protect stones from excessive impact while keeping noise low. Whether you're a first-time tumbler, a family exploring geology together, or an experienced hobbyist, the 3Lb Quiet Premium capacity handles projects of any size.
• Smart Controls for Consistent Results — Dial in the right tumbling speed for each polishing stage with 3 selectable speed settings. The 9-day programmable timer runs each stage automatically and shuts off when complete. Settings Recall stores your timer and speed configuration — so if power is interrupted, the K2 Quiet Elite picks up exactly where it left off without needing to be reprogrammed. Simple enough for beginners, reliable enough for experienced users — consistent results every time.
• Complete Kit for Day-One Start — Everything needed to start tumbling is included in the box — the rock tumbler, 3Lb soft rubber barrel, 1Lb of rough gemstones (9 varieties), complete 4-stage polishing grit set, ceramic pellets, sifter, 2 drive belts (1 spare), jewelry finding, and a full-color illustrated guidebook with step-by-step instructions. Great as a first rock tumbler for kids, teens, and adults — no additional purchases needed to start polishing stones from day one.
• Step-by-Step Guidance for Better Tumbling — The included full-color guidebook covers everything from initial setup to finishing your first batch — with detailed polishing techniques, troubleshooting steps, and practical tips like adding soapy water during polishing stages. Our US-based support team is also available anytime for polishing questions or machine help. Together, the comprehensive guidance and dedicated support help adults, beginners, teens, and families make real progress — from rough stones to finished keepsakes. Makes a complete geology or STEM gift for rock enthusiasts of all ages.
• Replaceable Key Parts for Long-Term Ownership — Core components are designed to be individually replaceable, not discarded. The motor, control panel, drive belt, rubber barrel, and metal lid kit are each available as replacement parts directly from KomeStone, with no planned end to parts supply. This stone polisher isn't a one-season purchase — it's a permanent part of your hobby setup.
