Which grit size is considered coarser?

The correct answer is: 46

The grit size of an abrasive material indicates how coarse or fine the material is. In this context, a lower number corresponds to a coarser grit. Grit sizes such as 36, 46, 60, and 80 reflect the number of particles per inch—essentially, the coarseness of the abrasive surface. The coarser the grit size, the larger the particles, which will remove material more quickly and create a rougher surface finish. A grit size of 36 is considered coarse, while sizes like 46, 60, and 80 represent increasingly finer abrasives. Therefore, choosing grit size 46 indicates it is coarser than 60 and 80, but finer than 36. Grit 36 would be the coarsest of the options provided, making it the best answer. This understanding is crucial in various applications, such as sanding or grinding operations, where selecting the appropriate grit size affects the texture and finish of the material being worked on.
