Abstract: A bond used in the manufacture of abrasive tools containing 3 - 75 wt. -% of copper, 15 - 90 wt.-% of chromium chloride; 0.01 - 10 wt.-% of a metal selected from the group including titanium, vanadium, chromium, zirconium, niobium, molybdenum, tungsten; 1 - 30 wt.-% of a low-melting metal; 2 - 30 wt.-% of the metal belonging to the iron subgroup of VIII group of the periodic chart.The employment of the bond according to the invention, for example in the manufacture of drill bits from an abrasive material based on cube boron nitride has made it possible to drill rocks of VIII - IX categories of drilling capacity at a drill speed and bit meterage exceeding 1.5 - 2 times the drill speed and bit meterage that have formerly been attained with the use of drill bits made of diamond with a bond containing tungsten carbide. While drilling rocks of VI - VIII categories of drilling capacity the bits made from cube boron nitride with the bond according to the invention surpass the carbide-faced bits, i.e.
