Circular grater for cutting plastic

A circular grater for cutting plastic for use in combination with a hand power-driven tool which has a motor within a housing and a shaft mechanically driven thereby and which includes:

• a. a circular mounting member, mechanically coupled to the shaft so that it rotates thereon;
• and
• b. a first flat disc-shaped member which is mechanically coupled to the circular mounting member;
• said circular grater comprises:
• a. a second flat disc-shaped member having a first surface adapted for grating a plastic surface and a second surface;
• b. a plurality of coupling members each of which having a disc-shaped head portion, which is mechanically coupled to said second surface of said second flat disc-shaped member, a cylinder-shaped portion of a particular diameter and a screw portion of a diameter smaller than the particular diameter, said coupling members adapted to have their said screw portions inserted into holes in the first flat disc-shaped member;
• and
• c. a fastening means for fastening said plurality of coupling members in order to mechanically couple said second flat disc-shaped member to the first flat disc-shaped member.
