Kubalulekile ukukhulisa ukusebenza kahle komsebenzi kanye nokunciphisa izindleko zokucubungula ukukhetha i-sawblade ngokunengqondo.Okulandelayo yizici ezithile ezicatshangelwayo lapho ukhetha i-sawblade:

1) Isici sokucutshungulwa kwezinto.Ungakhetha i-sawblade ekhethekile yezinto zamatshe, ukhonkolo noma uthayela ngokuya ngezinto ezahlukahlukene zokucubungula.

3) Isici sokusebenzisa imishini.Ukuze kuqinisekiswe impilo yokusika, i-saw blade egqokekayo kufanele igxilwe emshinini wamandla aphezulu.Ukuze kuqinisekiswe ukusebenza kahle kokusika, i-saw blade ebukhali kufanele igxilwe emishinini yamandla aphansi. kungcono ukukhetha i-saw blade egqokekayo lapho kusetshenziswa i- runout noma isisiki esinemba kancane, ngaphandle kwalokho khetha i-sawblade ebukhali yesisiki esisha noma esinembe kakhulu.
