Question

what is used to rate the coarseness of a band saws blade?
o hardness of the blades teeth
o length of the blades teeth
o teeth per inch
o revolutions per minute

Explanation:

The coarseness of a band - saw's blade is rated by the number of teeth per inch. Fewer teeth per inch indicate a coarser blade. Hardness of the teeth relates to durability, length of teeth is not the rating factor for coarseness, and revolutions per minute relate to the speed of the saw, not the blade coarseness.

Answer:

C. teeth per inch
