MBH K 830 / K 840 - is presented with crystals of the block form, with small deviations from the regular cubo-octahedral shapes. This economy type of powder ensures high strength and thermal stability peculiar to MBH X series. It is recommended for saw, drilling and grinding of different synthetic and natural building materials.

MBH K 850 / K 860 - are powders with the relatively high content of crystals of the cubo-octahedral shapes, high toughness and thermal stability. They are recommended for applying in the instruments assigned for sawing and drilling of concrete, asphalt and granite with high resource of stability of the tools.

MBH K 870 / K 880 - are presented with monocrystals practically without visible internal includings, have regular cubo-octahedral crystal shapes and very high toughness, which, in combination with an excellent thermal stability allows to use the instrument for effective sawing and drilling at higher powers of such materials as reinforced concrete, land asphalt and hard granite.
