ABSTRACT:
A cutting drum for a scarifying milling machine includes a rotatable drum having a generally cylindrical outer surface, and a plurality of flight blocks mounted onto the outer surface of the drum, defining a helical flight extending therearound. Each of the flight blocks includes a slot and at least one pocket formed therein. Each slot is generally rectangular and adapted to receive a tool holder. Each flight block includes a tool holder, having a generally rectangular body, removably mounted within the slot. A retainer is positioned within each pocket. Each retainer includes a planar tapered surface that is parallel to and engages one side of the rectangular body of the tool holder within the slot of the flight block to secure the tool holder therein.
