Description

  • The Original Brushless Rock Tumbler — Pioneered By KomeStone — KomeStone brought brushless motor technology to rock tumblers first — the K1 Pro is where it started. The professional-grade brushless motor delivers 20,000+ hours of operation, a 60% longer lifespan than traditional brushed motors, with less heat, less vibration, and quieter performance from day one.
  • Professional-Grade Controls — Smart LCD, 9-Day Timer & Memory Function — Features a smart LCD display, 9-day programmable timer with automatic shutoff, 3-speed precision controls, and a memory function that resumes your cycle after any power interruption. Military-grade thickened rubber barrel adds extra durability and noise reduction — built for professional hobbyists and serious collectors who demand more from every batch.
  • 2.5LB Large Capacity — Polish More, Faster — The extra-large 2.5LB rubber barrel lets you polish 2.5× more rocks per batch than standard 1LB tumblers. Ideal for dedicated collectors and gem enthusiasts processing precious agates, premium jasper, crystals, rough gemstones, or sea glass. The smoother brushless rotation helps protect delicate materials while maximizing polishing consistency and batch efficiency.
  • Complete Pro Kit — Everything Included For Day One — Includes the K1 Pro tumbler, 2.5LB rubber barrel, 1LB rough rocks (9 types), 4 polishing grits, ceramic media, sifter, jewelry fastenings, 2 extra belts, and a full-color illustrated guidebook.
