4.1 Operating principle
The drill and reamer attachments are powered by a
motor coupled through an Aesculap Acculan 3Ti cou-
pling.
The drill and reamer attachments convert the motor
rotation to rotation of the tool adapted in the respec-
tive attachment.
The drill and reamer attachments can be coupled to the
drive unit in three different angular positions at steps
of 120°.
Drill attachments are identified by their black unlock-
ing sleeves, whereas reamer attachments come with
blue unlocking sleeves.
