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).
