Claims

[Claims for Utility Model Registration] 1. A sawtooth-shaped tooth base is formed on the base plate, and the tooth base has a cutting blade at the tip of which the side surface protrudes laterally from the side of the base plate and has an inverted face and a rake face. 1. A structure of a saw tooth portion, characterized in that it has a pedestal, and ultra-hard abrasive grains are fixed to the circumferential surface of the cutting edge pedestal. 2. The saw tooth structure according to claim 1, wherein the diameter of the ultra-hard abrasive grains fixed to the peripheral surface of the cutting blade base is 10 μm or less.
