Abstract (en)

[origin: WO2021259652A1] The invention relates to a method for producing a green body for a machining segment (51) from a pulverulent or granular first matrix material (56) and first hard material particles (57), a lower face (61) of the machining segment being connected to a green body of a machining tool. The machining segment (51), on an upper face (62) opposite the lower face (61), has a projecting portion (Δ) of the first hard material particles (57).
