金剛石鋸片與切割片的功能主要包括兩個方面，鋒利度和耐磨度。在鋸切過程中，尖利度表現為切割效率的凹凸，耐磨度則表現為鋸片使用壽命的長短。效率凹凸和壽命長短是衡量金剛石鋸片與切割片綜合功能的兩大重要目標。

　　進行金剛石(shi)(shi)鋸片(pian)(pian)與(yu)切割(ge)(ge)片(pian)(pian)設計的(de)(de)意(yi)圖是(shi)為了(le)使(shi)(shi)其在使(shi)(shi)用過程中表(biao)現出理想的(de)(de)工作效率(lv)和(he)使(shi)(shi)用壽命。金剛石(shi)(shi)鋸片(pian)(pian)與(yu)切割(ge)(ge)片(pian)(pian)切割(ge)(ge)效率(lv)的(de)(de)凹凸和(he)使(shi)(shi)用壽命的(de)(de)長短與(yu)刀(dao)頭的(de)(de)pei方(fang)有著親近的(de)(de)關系，而刀(dao)頭pei方(fang)主(zhu)要(yao)取決于(yu)所選金剛石(shi)(shi)的(de)(de)參(can)數、胎體參(can)數等(deng)。

　　胎體(ti)工作面上金剛石的(de)均勻(yun)密度Φ越(yue)大，則刀頭(tou)的(de)耐磨度越(yue)好，刀頭(tou)的(de)使用壽命(ming)越(yue)長;相反，Φ越(yue)小，則耐磨度越(yue)差，刀頭(tou)使用壽命(ming)越(yue)短。
