M22-Wide vs M22 "Rock Crusher"

The M-22 gear teeth are cut at a noticeably lower angle (not quite at a straight angle as some people say). This lower angle of the teeth imparts greater strength to the gears, but it also increases the noise caused by the meshing of the gears. This higher level of noise is where the nickname "Rock crusher" originated.
