The abrasive size of a grinding stone is also known as the ___________.

• A. Grit
• B. Mesh
• C. Grade
• D. Texture

Answer: (A)

Grit is the term for the abrasive size on a grinding stone. The grit number tells you the particle size: lower numbers mean coarser, larger grains that remove material quickly and leave a rough finish, while higher numbers use finer grains for a smoother finish and more precise control. Mesh, grade, and texture describe other properties—mesh relates to screening size, grade to the wheel’s bonding hardness, and texture to surface feel—not the actual grain size.
