Thumler's Tumbler AR-2 Rotary Rock Tumbler
Double the barrels, double the possibilities—perfect for beginners and hobbyists ready to do more.

The Thumler's Tumbler AR-2 is a step up for hobbyists looking to polish rocks, clean metals, or run multiple batches at once. With its dual-barrel design, quiet operation, and rugged build, the AR-2 offers the same trusted quality as the AR-1—with twice the capacity and flexibility.

Key Features & Benefits:

  • Heavy-Duty Steel Base with Powder-Coated Finish
    Designed for durability, the AR-2 features a sturdy steel frame and a tough powder coat finish that resists wear, corrosion, and years of consistent use.

  • High-Quality Thermally Protected Motor
    The motor is built for continuous operation and includes thermal protection to prevent overheating—keeping your tumbler safe, reliable, and ready for long polishing sessions.

  • Two 3-Pound Rubber Barrels (Each Holds ~2 lbs of Rock)
    The AR-2 comes with two soft rubber barrels that reduce noise while delivering excellent tumbling results. Run two different stages at once—like coarse and fine grit—or polish two types of materials without cross-contamination.

  • Versatile Applications
    Ideal for polishing rocks and gemstones, cleaning brass casings, restoring coins, or refining metal parts. The dual barrels make it a great tool for multitasking or increasing your output.

  • Beginner-Friendly with Room to Grow
    The AR-2 offers an easy learning curve for beginners, with the added capacity to grow alongside your tumbling skills. It's a flexible solution for those who want a quiet, reliable machine with more capability.

Whether you're stepping up from a single-barrel model or starting strong with added capacity, the Thumler’s Tumbler AR-2 is a quiet, rugged, and highly versatile choice that helps you get more done—all while delivering beautiful, polished results.
