The 9522-100 is used primarily in light industrial and residential applications for concrete grinding and profiling, as well as removing sealer and top coat. It also creates exceptional profiles for concrete prep and restoration prior to polishing concrete. Brazed trapezoids can be used with all National planetary grinders.

The 9522-100 is sold individually. To build a complete set for your grinder you will need to purchase 6 - #9522-100.
