CUTTER
Document Type and Number:
Japanese Patent JP2007290104
Kind Code:
A
Abstract:
To provide a cutter capable of cutting a pipe-like cutting workpiece so that a cross section forms an approximately complete horizontal face.
A cutting blade 1 is provided with a mounting hole 3 at a central part of a disc-like body 2, and an outer periphery of the body 2 is sharpened and functions as a blade tip 4. Seeing the cutting blade 1 form a side, one side of the blade tip 4 forms a horizontal face 5, and the other side forms an inclined face 6 so that thickness at a center of a substrate 2 becomes thick. Because an inclined face 6 is provided only a single side across the blade tip 4, the cutting blade 1 forms an asymmetrical shape seen from the side.
