Fox is not a brand used in France. There is no manufacturer in
Germany called Fox.
Fox is a US trade mark for Burs made by Brasseler (Komet) one of the
largest tungsten & Carbide cutting tool manufacturer in Germany.
I agree Busch is No.1 & Maillefer is No. 2 for Jewelry and Dental. I
do not know much about Meisinger. But I do know that Fox Round burs
and particularly their Carbide burs have the best (round) shape among
all the 4 kinds.
