The present invention provides a beveling tool including: a body with a shaft hole formed through the center; a plurality of cutter blades arranged at predetermined distances on the circumferential surface of the body, each having a radial primary blade with a radial primary relief angle ranging from about 10 to about 20 degrees and a radial secondary blade with a radial secondary relief angle ranging from about 25 to about 35 degrees (or about 35 to about 45 degrees); discharge grooves formed longitudinally between the cutter blades to discharge chips produced in beveling; and a shank inserted in the shaft hole of the body, in which the body and the shank are connected by brazing. With the beveling tool of the present invention, it is possible to smoothly discharge chips produced in beveling and to prevent damage to the cutter blades.
