The existing stone cutting tool, the tool bit is constituted by the sole grade's grinding material, when cutting the rough stone, the cutting speed is quick, the cutting efficiency is high, but the cutting surface fluctuates in a big way, becomes rough, after the cutting, grind and polishing take long time to do, if use the fine grinding compound, the cutting face is smooth, but the cutting speed is slow, the cutting efficiency is low, therefore the existing stone material cutting tool cannot have the high efficiency to cut the stone which have the smooth cutting surface, in view of this, how to keep the high working efficiency and get smooth cutting surface?

现有石材切具刀头由单一粒级的磨料构成，使用粗料时，切割速度快，切割效率高，但切割面起伏大，变得粗糙，切割后研磨抛光耗费时间长，使用细磨料，切割面较平整，但切割速度慢，切割效率低，因此现有石材切具不能高效率地切割出平整的石材，针对这一现状，如何既能高效率切割，又能使切割面保持平整呢？
