German term or phrase:Drehmitnamenuten
In a patent relating to a drill hand tool: "Bohrer für handwerkzeuggeräte weisen zur Aufnahme in die Werkzeugaufnahme an einem Ende des Schaftes ein Einsteckende mit Drehmitnamenuten und Verriegelungsnuten auf."
Would anyone have a clue what is meant by "Drehmitnahmenut."

rotary tightening groove (or keyways)
Explanation: and locking grooves (or keyways) for the "Verriegelungsnuten".
The text describes the chuck of a drill which receives the drill bit. Inside the chuck are "jaws" into which the drill bit is inserted. You first tighten and then lock the bit into place.
Please keep in mind, though, that this is a "generic" term, which would certainly be understood, but the designer of the drill could call these components by a whole number of different names.

Explanation: 'Mitnahmenut' is relatively rare, but'
'Mitnehmernut' means a keyway (in a shaft) use to transmit torque, and a related term is 'Mitnehmerstift' = drive pin. The drill bit is probably similar tio the Bosch SDS system, whic uses several grooves (or slots) to transmit the torque to the drill (for rotary motion); the purpose of using slots is to allow the bit to slide back and forth for hammering motion (percussion drilling).
from the ref:
The versatile Slot Drive System fits all rotary hammers that specify an SDS-Plus shank. Positive drive slots deliver maximum drilling torque and maximum hammering energy for faster drilling.
BTW, the Verrieglungsnut would be a 'locking groove' or a 'retainer groove'.
Explanation: Since the text uses 'Drehmitnahmenuten' where normally 'Mitnahmenuten' would be adequate, 'rotary drive slots' would be justified (even if it sometimes seems that patent copywriters are judged by the sheer volume of text they produce).
