Re: Edelstall cutting tool system

Interesting idea.? If the question is why didn't this idea take off, I don't know.? Perhaps because it adds more cost to buy the blank compared to plain blanks.? And perhaps not with much benefit.
Since you have to grind the tool bit some anyway, grinding a little side clearance is no big deal.
Also, that shape reduces the cross section the length of the blank and therefore reduces the stiffness.? With a square blank, the part not ground will be stiffer.
M2-HSS is the most common and affordable tool blank alloy and is what most people are buying even if they don't know it.
On those fancy cross section bits, I just don't see enough of a plus (very modest convenience) compared to minuses (cost and weaker cross section).
