Size: 4.5″ 16 Grit Zec Wheel ZEC wheels are a disposable type of grinding disk that have silicon carbide adhered to the surface. Their aggressive quality lets you tear off epoxies and carpet glue without having the disc load up. This is the most popular Zec wheel sold. It has an excellent balance of aggressiveness and longevity. The ridges in the abrasives allow new cutting surfaces to be exposed as the old ones wear out.
