Abstract

A cutting tool including a cutting edge part made of cBN sintered material bonded through a brazing material for bonding and a cutting tool body made of WC-based cemented carbide is provided. In the cutting tool, the cutting edge part made of cBN sintered material and the cutting tool body made of WC-based cemented carbide are brazed by using a blazing material for bonding including: 35-40% of Ti in a mass ratio; 35-40% of Zr in a mass ratio; 5-15% of Ni in a mass ratio; and the Cu balance including inevitable impurities.
