English translation:egg shaped / half-spherical hollow milling cutter
Explanation:
egg shaped hollow mill
half-spherical hollow mill

this is a "hollow mill" for sure, but I can't find any example of a half-spherical one.

"Hollow mill

Hollow milling cutters, more often called simply hollow mills, are essentially "inside-out endmills". They are shaped like a piece of pipe (but with thicker walls), with their cutting edges on the inside surface. They are used on turret lathes and screw machines as an alternative to turning with a box tool, or on milling machines or drill presses to finish a cylindrical boss (such as a trunnion)."
