The present invention relates to a Styrofoam hole processing device which can facilitate hole processing on Styrofoam by including a rotating blade and an inner blade at the end of a body unit in a double type, and can evenly cut the Styrofoam in processing a hole by reducing rotational friction due to a rotation motion. The Styrofoam hole processing device comprises: a body unit (100) in a hollow cylindrical shape; and a support (200) where a motor rotary device connecting pin (220) is formed at the center of the top of the body unit (100) in order to transmit driving force to the body unit (100). The body unit (100) comprises: multiple rotating blades (110) which are formed on the bottom of the body unit (100) with a sawtooth shape and are aligned in a spiral direction in order to cut a circular hole on Styrofoam; inner blades (120) which protrude inward from the central unit of the rotating blade (110) respectively, are cut in the same direction as the rotating blades (110) in order to reduce the resistance of rotational friction during Styrofoam cutting; and multiple body holes (130) which are formed on the side surface of the body unit (100) in order to smoothly discharge Styrofoam cutting chips and to reduce the resistance of rotational friction. The support (200) includes multiple supporting holes (210) on the front side thereof in order to smoothly discharge of the Styrofoam cutting chips. |
