The high density and sharp edges of the embedded abrasive material contribute to a shortening of process times and are said to produce excellent surface finishes.

Walther Trowal's new HDC media (High Density Cut) consists of a plastic carrier filled with zirconium silicate, thus combining the advantages of lightweight plastic media with the high density of the abrasive filler material. This combination is said to yield metal removal rates that are comparable to ceramic media, a surprisingly low wear rate, and excellent surface finishes.
