Final answer:
The 60 grit wheel is finer than the 36 grit wheel because a higher grit number indicates smaller, finer abrasive particles.
Step-by-step explanation:
The wheel grit that is finer between a 60 grit and a 36 grit is the 60 grit. Grit number refers to the size of the abrasive particles on the wheel, with a higher number indicating smaller, finer particles. In this case, a 60 grit wheel has smaller abrasive particles than a 36 grit wheel, making it the finer option. This is important when selecting the appropriate grit for precision sharpening or finishing, as finer grits provide a smoother surface finish.
