Abrasives za a iya raba kashi biyu: talakawa abrasives (kamar aluminum oxide, silicon carbide, da dai sauransu) da superhard abrasives (lu'u-lu'u, cubic boron nitride, da dai sauransu.).
CBN da Jinzeshi sun fi na yau da kullun wahala da juriya, amma suna da tsada sosai.A lokaci guda, superhard abrasives suna da kyaun jagoranci mai zafi (ma'aunin zafin jiki na lu'u-lu'u shine sau 6 na jan karfe), yayin da abrasives na yau da kullun sune kayan yumbu, don haka suna adiabatic.
Superhard abrasive shima yana da babban diffusivity na thermal, wato yana da ikon watsar da zafi cikin sauri.Wannan siffa ta sa superhard abrasive suna da yanayin "yanke sanyi".Juriya na abrasion na superhard abrasives shima ya fi na talakawa abrasives, amma waɗannan halayen superhard abrasives ba yana nufin sun dace da kowa ba.tafiyar matakai nika.
