1.Cutting Structure o lenei ituaiga faʻamaufaʻailogaina ma le le faʻamaufaʻailogaina tolu pupuni:
O le ofuina-tetee o nifo e faʻaleleia i le tungsten carbide sili ona faigata e faʻasaga i luga o nifo mo le uʻamea nifo uʻamea.
2. Fua Fa'atulagaina o lenei ituaiga tolu pito papa ma'a :
Puipuiga fa'afuafua fa'atasi ma fa'amau fa'amau i luga o le mulivae ma mea fa'aofi fua i luga o le fua o le cone, fa'apipi'i tungsten carbide ma fa'asaga faigata i luga o le si'usi'u ofutino e fa'ateleina ai le gafatia o le uuina o fua ma le ola ola.
3. Tulaga Fausia o lenei ituaiga tolu pito papa cone :
Fa'amau fa'aoloa maualuga fa'atasi ma mata fa'aoso lua.Polo loka le cone. Tuʻi faʻasaga i foliga malo ma le ofuina uʻamea tetee.Abrasion teteʻe ma faoa faamalosi tetee o le tauaveina ua faaleleia
