Technical Features

  • Silicon Carbide Abrasive: A hard, sharp abrasive material that cuts aggressively into masonry and concrete surfaces, enabling efficient material removal without premature wear.
  • 20 Grit Rating: Coarse grit designation delivers rapid stock removal, making it suited for heavy-duty smoothing, shaping, and deburring of rough edges on tile, block, and cast concrete.
  • Fluted Block Design: Longitudinal flutes channel debris and slurry away from the work surface during use, reducing clogging and maintaining consistent abrasive contact.
  • Integrated Handle: Built-in handle provides a secure, controlled grip during operation, reducing hand fatigue over extended use.
  • 6 x 3 x 1 in Block Dimensions: Full-size format provides a broad working face, allowing coverage of larger surface areas per pass compared to smaller rubbing stones.
  • 4.65 lb Mass: Substantial weight assists in applying consistent downward pressure during rubbing, supplementing manual effort for more uniform material removal.

Applications

  • Smoothing and dressing cut edges on tile, brick, and concrete block
  • Removing form lines, high spots, and surface irregularities from poured concrete
  • Shaping and fitting masonry units during installation
  • General abrasive surface preparation on masonry substrates
