Other factors also affect the performance of the tools, suchy as the diamond size, diamond concentration and diamond grade, the hardness of the bond, the cutting power(torque) of the equipment: the segment and slot geometry of the steel core, and how well the blade specification and best of all the correct choice of the blades is matched to the material being cut. 2) The appearance exposure of the diamond: do not judge only by the appearance exposure, due to the mixing and sharpening process, sometimes a high grades segment looks less quality, and small diamond size, but in fact it is perfect inside.
