Trapezoid Diamonds

Used primarily in light industrial and residential applications for concrete grinding and profiling as well as sealer and top coat removal. Provide excellent surface profiles for new coatings, epoxies, or stains. Also create exceptional profiles for concrete preparation and restoration prior to polishing concrete. Brazed trapezoids can be used with all National planetary grinders.
