Question

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

Explanation:

The coarseness of a band - saw's blade is determined by the number of teeth per inch. Fewer teeth per inch indicate a coarser blade, while more teeth per inch mean a finer blade. Hardness of the blade's teeth relates to durability and wear - resistance, revolutions per minute is about the speed of the saw, and length of the blade's teeth is not a factor in rating coarseness.

Answer:

B. teeth per inch
