Industrial Synthetic Diamond Grit: Engineered with high-density diamond segments bonded to a tough steel matrix, ensuring rapid concrete stock removal and long abrasive wear life.
Universal 4-Inch Angle Grinder Fit: Designed with an exact 100 mm diameter and standard 16 mm center arbor hole, mounting directly onto common 4-inch handheld angle grinders.
Aggressive Planar Surface Leveling: Quickly strips high spots, smoothing concrete seam ridges, rough masonry joints, and cured mortar beds flat and uniform.
Integrated Air Cooling Holes: Ventilated steel dish design promotes continuous airflow around the disc face to expel ground powder and dissipate frictional heat during dry grinding.
Multi-Substrate Masonry Utility: Delivers clean surface preparation across cured concrete slabs, terrazzo floors, natural granite, marble, brickwork, and cementitious coatings on job sites across Nepal.
