Beveling cutter having helical edged blades and discharge grooves

A beveling tool comprising

• a body with a shaft hole formed through a center of the body,
• a plurality of cutter blades arranged at predetermined distances on a circumferential surface of the body and having a helix angle in a range from about 1 to about 45 degrees,
• discharge grooves formed longitudinally between the cutter blades to discharge chips produced in beveling, and
• a beveling angle in a range from about 15 to about 60 degrees.
