The  Evaluation  of  the  competitiveness  of  highly  porous  circles  on  the  basis  of  cubic  boron  nitride,  microcrystalline corundum   and  white electrocorundum on  the performance  of the process, the time spent on cyclic editing and the complexity  of  the  formation  of  the  working  profile  of  long  passages  of  hardened  high  speed  steel. 
Significant benefits in the same conditions showed highly porous circle of cubic boron nitride, which provided specific  performance  grinding  compared  to  rangebased  microcrystalline  corundum  more  than  3  times  and  7,5  times larger than the circle of white electrocorundum. By a combination of factors highly porous elbor circle turned out to be more  economical  from  the  point  of  view  of  the  cost  of  the  tool.
