Features:

  • STAGE 1 EXTRA COARSE GRIT FOR INITIAL SHAPING: This 60/90 grit silicon carbide is designed for the first stage of rock tumbling, helping break down rough edges and shape stones. Ideal for starting the polishing process by removing surface imperfections and preparing rocks for finer stages.
  • AGGRESSIVE CUTTING FOR FASTER MATERIAL REMOVAL: The extra coarse grit provides strong abrasive action for shaping and smoothing hard materials. Suitable for reducing rough surfaces efficiently and preparing stones for the next stages of polishing.
  • COMPATIBLE WITH ROTARY & VIBRATORY TUMBLERS: Works with most rock tumblers, including rotary and vibratory machines. A versatile option for maintaining your rock polishing workflow or restocking Stage 1 grit.
  • IDEAL FOR ROCKS, MINERALS & SEA GLASS PROJECTS: Can be used on stones, minerals, and glass materials. Also suitable for creating textured finishes or shaping materials before finer polishing stages.
  • USA OWNED BRAND WITH TRUSTED QUALITY: Offered by a USA-based, disabled and veteran-owned company. MJR Tumblers provides reliable rock tumbling supplies designed for consistent performance and ease of use.
