JSC Terekalmaz has been producing synthetic polycrystalline ARS-3 and ARS-4 diamonds (of the spec type) since 1977.

Currently, ARS-4 grinding powders with a grain size from 2000/1600 to 500/400 microns are produced. and spec-type blanks of arbitrary geometric shape with linear dimensions of 4*4mm. (cylinder, cube ,truncatedcone, rod, etc.)

Good physical and mechanical properties and sufficiently high temperature resistance make it possible to use these diamonds in the manufacture of a variety of tools on metal bundles for work in particularly harsh conditions. These are cutting and processing of natural stone, concrete, building materials, straightening of grinding wheels, drilling of medium-hard rocks, including for oil and gas.
