as a machinist, what bothers me, there is no mention of what angle the drill is sharpened to.
135* ? 118*? 90*? something else ?
I've been asking that for years...common consensus is 118 degrees which is considered the standard.
118* is standard.
if i had a factory flywheel to look at, i could easily determine the drill angle.
however, i'm an automatic guy, as i have never been able to speed shift a stick worth a hoot.
therefore, all my parts stash contains just "shift for you" items.
