This paper presents the results of examinations on definition of linking strength of sintered
on the steel mount by a method of intensive electrosintering at heightened pressure briquetted layers from different matrix materials designed for usage in rock-destroying and dressing instruments. Is shown, that due to saving of diamonds properties and high mechanical properties of matrix the designed instrument for dressing and drills for handling a natural rock has high indexes of
endurance and productivity.
