I would pick the Busch bur, why? You can actually 'see' what is taking
place during the removal of the metal on the tip of the claw/prong!!! I
like this version better, as the 'teeth' are right against the edge of the
bur. Unfortunately, the next pattern/design the deep-cutting teeth are more
"aggressive" in the cutting process. Plus, the teeth are not truly against
the edge of the bur. Much "modification" needs to take place & not cost
effective!!! Hope this review is helpful.
