Abrasive Grit - Silicon Carbide Graded grit means that all of the particles are very close to the same size. Highland Park graded grit is be carefully processed to insure that all of the particles are close to the same size resulting in consistent and repeatable grinding and polishing stages
"Rock tuler grit", also known as "rock polishing grit", is a silicon carbide powder that is much harder than the types of rocks that are commonly polished in a rock tuler. If it is tuled in a barrel with rocks and water the abrasion caused by the grit particles rounds the sharp edges off of the rocks.
2010-2-5 · Silicon carbide is a harder abrasive, but aluminum oxide is plenty hard for steel. Either will work. The biggest differences in stones are how they cut, which is a funtion of the abrasive and the binder used to "glue" the abrasive particles together. There is no way to know until you try them, sadly.
