Description

Professional Grade Diamond Surface Preparation Wheel

The OX Tools 4-Inch Double Row Diamond Cup Grinder OX-PCDT-4 is a precision-engineered abrasive wheel designed for aggressive surface leveling and smoothing of cured concrete, masonry, and natural stone. Featuring a double-row segmented configuration and industrial-grade diamond grit, this disc maximizes material removal rates while providing a refined finish for floor preparation or masonry repairs. Its 15,300 RPM rating and heat-treated steel core ensure robust durability under heavy-torque loads for both wet and dry construction applications.

Best Used For:

  • Concrete Floor Leveling: Flattening uneven surfaces, removing high spots, and smoothing out rough formwork shuttering marks on cured concrete.
  • Tough Coating Removal: Stripping away stubborn construction adhesives, glues, epoxies, and thin coatings prior to new floor applications.
  • Natural Stone Fabrication: Shaping, profiling, and preparing abrasive masonry or natural stone surfaces for final finishing treatments.

Key Performance & Safety Features

  • Double Row Configuration: Concentrates downward grinding pressure onto a dense layer of segments to accelerate material removal rates.
  • Industrial Diamond Grit: High-grade diamond concentration ensures extended service life in highly abrasive concrete and masonry substrates.
  • Precision Balance Engineering: Minimized operating chatter and vibration to lower operator fatigue and protect angle grinder motors.
  • Advanced Cooling Vents: Steel core design facilitates maximum airflow to cool the diamond matrix and optimize dust clearance.
  • Wet or Dry Utility: Versatile design engineered specifically for high-velocity dry grinding or wet suppression applications.
