Abstract

Cutting arrangement has a fork-like holder (30) with two holding arms (34). The arms each have a stop side (36) which lie on narrow sides of a tooth shaft. The stop sides and the narrow sides form an interlock across the insertion direction with a profile. A recess (38) is provided on the stop side of one holding arm and on the narrow side of the tooth shaft. The recess forms a through-hole for a fixing pin. Preferred Features: The tooth shaft is held on both sides with two fixing pins.
