ABSTRACT:
An apparatus for fixing an annular cutter to an arbor comprises an arbor and a rotation transmitting member coaxially fixed to the arbor. Inclined grooves which receives locking pins extend from the inner peripheral surface to the outer peripheral surface of the rotation transmitting member toward the arbor. A guide ring is axially slidably mounted on the rotation transmitting member and has pressing faces and restricting grooves defined by the pressing faces. Each restricting groove has a dimension which can receive the respective locking pin. A holding mechanism is provided for holding the guide ring in a normal state in which the pressing faces press the locking pins inward along the inclined grooves. The holding mechanism can moved toward the arbor together with the guide ring so as to allow the locking pins to enter the restricting grooves. An annular cutter has a cutter body and a shank connected to the cutter body and inserted into said rotation transmitting member. The outer cylindrical surface of the shank is formed with an annular engaging groove which aligns the inclined grooves when the said shank is fully inserted in the rotation transmitting member.
