Ama-indexable blade i-blade ebopha into efakwe i-polygonal ecutshungulwe ngaphambili enemiphetho embalwa yokusika emzimbeni wamathuluzi ngokucindezela ngomshini. Lapho unqenqema lokusika luba buthuntu ngesikhathi sokusetshenziswa, udinga kuphela ukukhulula ukubopha kwe-blade bese ukhomba noma ushintshe i-blade ukuze unqenqema olusha lungene endaweni yokusebenza, bese luqhubeka lusetshenziswa ngemva kokuboshwa. Ngenxa yekhono eliphezulu lokusika kanye nesikhathi esincane sokusiza kwethuluzi elikhonjisiwe, ukusebenza kahle komsebenzi kuyathuthukiswa, futhi umzimba wokusika wethuluzi le-indexable ungasetshenziswa kabusha, okugcina izindleko zensimbi nezokukhiqiza, ngakho umnotho wawo muhle. Ukuthuthukiswa kwama-indexable cutting blades kuye kwakhuthaza kakhulu inqubekelaphambili yobuchwepheshe bethuluzi lokusika, futhi ngesikhathi esifanayo, ukukhiqizwa okukhethekile nokujwayelekile kwama-indexable cutting blades kuye kwakhuthaza ukuthuthukiswa kwenqubo yokukhiqiza yokusika izindwani.
