This sintered body has a first material, a second material, and a third material. The first material is a cubic boron nitride. The second material is a compound including zirconium. The third material is an aluminum oxide which includes fine aluminum oxide. The sintered body has a first region in which the fine aluminum oxide is dispersed in an amount of 5% to 50% by volume in the second material. Along any straight line in the first region, an average value of a continuous distance occupied by the fine aluminum oxide is 0.08 μm or less, and a standard deviation of the continuous distance occupied by the fine aluminum oxide is 0.1 μm or less. |

The invention relates to an insert brazed on a body of cutting tools (101), consisting of: a metal substrate (11), in the form of plates, having a surface for attachment to the tool body; a high-temperature, brazing, alloy layer (12); an intermediate layer; and a ceramic plate (14). The brazing alloy layer connects the metal substrate (11) of the ceramic plate (14) via the metal layer (13). A low-temperature brazing layer (16) connects the insert (1, 1') to the body of the tool (101). |
