The invention relates to a method of making a monolayer abrasive tool containing a monolayer cubic boron nitride (cBN) abrasive grit bonded to a steel substrate. Method comprises applying uniformly on the surface of a plain carbon steel substrate, a brazing paste made of Ag-Cu eutectic alloy (72% Ag, 28% Cu) mixed with 1% to 3% of titanium or titaniumhydride powder, placing cBN grits (nono crystalline/microcrystalline type) on said brazing paste, uniformly placing said grit on the surface of said steel substrate, drying the tool substrate alongwith the brazing paste and cBN grit at a temperature varying from 75°C - 125°C for 5 to 15 minutes, placing the abrasive
