These "top of the line" mounted stones are made with a unique combination of Sol Gel ceramic grain and our high quality Pink fused aluminum oxide to produce the sharpest cut, and most durable of the friable grain vitrified bond stones. This combination gives it a distinctive purple color.
Ceramic grain is the most friable grain produced. Due to the sharp cutting action, this mixture is used on high nickel alloys for the aerospace industry, as well as many common varieties of steels and alloys.
All are mounted on 1-1/2" long plated, 1/8" steel shanks. Also available on 3mm shanks. Grit varies from 80, 100 to 120.
