Multi-purpose beveller

A multi-purpose beveller comprising:

• a support holder coupled to a beveller and including a coupling aperture formed in a guide plate;
• an adapter coupled to a power shaft of the beveller and including an insertion aperture formed in a center of the adapter;
• a rotary cutter fixedly fitted into the insertion aperture;
• and
• a beveling tool including an upper surface that faces both the guide plate and the rotary cutter, a lower surface opposite to the upper surface, and a through aperture penetrating the beveling tool from the lower surface to the upper surface, the beveling tool being mounted to the guide plate by a screw that passes through the through aperture of the beveling tool and the coupling aperture of the guide plate, the beveling tool including two sides that form an acute angle, the beveling tool further including support protrusions and an interference prevention unit,
• wherein the support protrusions are formed secured to an inner surface of a cutter exposure aperture and an outer surface of the guide plate in a concentric circle shape on the top surface of the beveling, and the interference prevention unit is located at the intersection of the two sides, and
• wherein, at a front end of the intersection of the two sides, a round side is formed to protrude outwardly from a blade edge of a center part of the rotary cutter, such that an imaginary line extended from the blade edge in an axial direction of the rotary cutter, comes in contact with the upper surface of the beveling tool.

A multi-purpose beveller comprising:

• a support holder connected to a top of a desk-type beveller and including a coupling aperture formed in a guide plate;
• an adapter formed at an upper part of a power shaft of the desk-type beveller and including an insertion aperture formed in a center of the adapter;
• a rotary cutter fixedly fitted into the insertion aperture;
• and
• a beveling tool including an upper surface that faces both the guide plate and the rotary cutter, a lower surface opposite to the upper surface, and a through aperture penetrating the beveling tool from the lower surface to the upper surface, the beveling tool being mounted to the guide plate by a screw that passes through the through aperture of the beveling tool and the coupling aperture of the guide plate, the beveling tool including two sides that form an acute angle, the beveling tool further including support protrusions and an interference prevention unit,
• wherein the support protrusions are formed secured to an inner surface of a cutter exposure aperture and an outer surface of the guide plate in a concentric circle shape on the bottom surface of the beveling tool, and the interference prevention unit is located at the intersection of the two sides, and
• wherein, at a front end of the intersection of the two sides, a round side is formed to protrude outwardly from a blade edge of a center part of the rotary cutter, such that an imaginary line extended from the blade edge in an axial direction of the rotary cutter, comes in contact with the upper surface of the beveling tool.
