An improved cutting insert cartridge arrangement for quick and easy mounting of cutting inserts to and removal from a rotary cutting tool, comprising a cutting insert receiver for the cutting insert, the insert receiver itself being quickly and easily removed from the rotary cutting tool body. The cutting insert receiver may have an outer end portion with an opening therein for receiving a cutting insert, the outer end portion being configurable to apply a varying lateral grasping force against an inserted cutting insert. The cutting insert receiver may be frusto conical in shape to mate with a complementary frusto conical recess in the rotary cutting tool body, whereby securing the receiver in the recess serves to apply the lateral grasping force against an inserted cutting insert due to the camming action between the mating surfaces of the two frusto conical members. Alternatively, a movable holder for holding the insert receiver may be coupled to the cutting insert receiver and slidable axially relative thereto to configure the outer end portion to increase grasping holding force against an inserted cutting insert in a first axial position of the movable holder, and to diminish grasping holding force against an inserted cutting insert in a second axial position of the movable holder.
