• Long-term heavy-duty use may wear belts over time. 𝐑𝐞𝐪𝐮𝐞𝐬𝐭 𝐮𝐩 𝐭𝐨 𝟓 𝐞𝐱𝐭𝐫𝐚 𝐛𝐞𝐥𝐭𝐬 𝐚𝐭 𝐧𝐨 𝐜𝐨𝐬𝐭 𝐛𝐲 𝐜𝐨𝐧𝐭𝐚𝐜𝐭𝐢𝐧𝐠 𝐨𝐮𝐫 𝐬𝐮𝐩𝐩𝐨𝐫𝐭 𝐭𝐞𝐚𝐦: 📧 𝐬𝐮𝐩𝐩𝐨𝐫𝐭@𝐚𝐭𝐨𝐫𝐨𝐜𝐤.𝐜𝐨𝐦.We’re here to ensure your A1 Pro tumbler always performs like new.
• Designed by Experts — Proven AtoRock Quality: Developed by a U.S.-based team with over 10 years of rock tumbling experience, AtoRock focuses exclusively on building reliable, professional tumblers. With a proven lineup from A1 (entry-pro model), A1 Pro (dual-barrel tumbler) to A3 (22lb heavy duty rock tumbler), every machine is rigorously tested and refined to meet the demands of serious hobbyists, collectors, and workshops—not casual or disposable use.
• Powerful Brushless Motor – No Maintenance, No Compromise: The high-efficiency brushless motor delivers strong, stable power and a longer lifespan. It runs with less heat and no dust, unlike traditional brushed motors that can overheat and wear out over time. No carbon brushes, no mess, and no drop in performance.
• Dual-Barrel Design (4 lb × 2) – Parallel Cycles, Faster Results: Run both barrels simultaneously to handle larger batches or stones of different hardness. The dual-barrel system also allows parallel tumbling cycles—run Cycle 1 in one barrel while progressing to Cycle 2 in the other—helping reduce overall project time. Compared to a single 4 lb barrel, processing efficiency can increase by up to 100% without extending runtime.
• Smart Controls – 3 Speeds + 9-Day Timer: Dial in your perfect polish with four speed settings and a programmable 9-day timer featuring auto shut-off and memory recall. Ideal for users who want tighter control over grit stages and cycle timing.
• Complete Kit – Built for Serious Tumbling: Includes everything you need to get started or upgrade: 4lb barrel x 2, 2lb premium rough gemstones, 8 polishing grits, 2 spare belts, screwdriver, jewelry findings, mesh strainer, and a full-color instruction manual. Ready for pro-level polishing out of the box.
