- Fastest grain removal in the marketplace for carbon based steels (26% more than the competition) and second best after CGW Z-Stainless discs on stainless steels, while offering excellent life.
 - Recommended for aggressive use and heavy duty applications.
 - Active grinding agent provides cool cutting with light pressure.
 - Special optimized resin bond offers maximum cutting capacity, strong edge stability and long life.
 - remium Zirconia Alumina grain with a poly/cotton heat treated backing. The poly/cotton combination provides low stretch and strength for the high Zirconia concentration that Z3 contains.
