FIELD: process engineering.
SUBSTANCE: invention relates to grinding and may be used for production of abrasive tools with coating. Article consists of substrate with abrasive coating (5) on one side and, on opposite side, a securing layer with coarse material. Line of lower resistance is made at said article to extend through securing layer without penetrating to article outer surface for separation of one of the article from the other.
