This standardization is usually measured in either U. Using a coarse grit at low pressure will result in inefficient cutting, while using fine grit at high pressure can over-clean and warp thin sheet metal.

The size chart for shot is different; a #5 steel shot will clean differently than a #5 angular grit because of its round shape, which is better suited for stress relief rather than material removal. Environmental and Safety Considerations.
Coarse grit creates a deep, rugged profile known as a "tooth," which provides a strong mechanical bond for protective coatings like epoxy or zinc. Sieve Mesh size, which indicates the number of openings per linear inch, or in microns (µm), which measures the particle diameter.

Unlike standard measurement scales, a higher number indicates a smaller particle size. Therefore, a 60-grit product is significantly coarser and more aggressive than an 80-grit product.
