FIELD: process engineering.
SUBSTANCE: set of inventions relates to inserts, cutters and production thereof. Said insert comprises lattice to form interstices and catalyst material deposited therein in at sintering which produces said lattice. Note here that said catalyst material facilitates the growing of lattice and comprises the alloy approximating to eutectic one. The latter features the composition making within plus or minus ten atomic mass percents of eutectic composition and thermal expansion factor smaller than that of cobalt.
EFFECT: higher resistance against high temperatures.
