Resistant abrasives are made to withstand harsh working conditions with minimal impact to their cutting and polishing capabilities during the entire work period. Good examples of reinforced abrasives are diamonds which require high quality materials with excellent wear resistance. Resistant abrasives apply to industrial uses where constant grinding or polishing is done, for example in metal recycling plants or in large scale manufacturing. They are effective under conditions of extreme pressure, temperature, and friction. In resistant abrasives, the bond agents must set the abrasive grains so rigidly the resultant tool is dependable and durable.
