There is One thing should be pay special attention: for high temperature & wear-resisting bond, high grade diamond and hard cutting material, if you mix some low grade diamond, would decrease obviously the cutting efficiency and life.

Diamond grit 30/35-60/70 is mostly used in blade. When cutting high abrasive material the grit should be coarse, cutting very hard,high density Granite and crisp glass, the grit should be fine.

Increasing concentration of diamond can longer the blade life by reducing cutting force of each diamond which reduce the wearance.But on the other hand,it reduce also the cutting efficiency and increase the cost. Theoretically, there would exist a most economic concentration.
According to different cutting requirements, the concentration of blade would range 10/50%. Small blade mostly range between 10-20%, medium diameter blade 15-40%, big size blade 25-50%.

Usualy, cutting soft or low abrasive/ no abrasive material like glass, glazed ceramic tiles, soft marble, the bond should be soft, not wear resistance and some brittleness bond like bronzed bond, cobalt bronze bond or Iron bronze bond.
Diamond should have sharp angularity, rough surface. Cutting speed,depth, feeding, can be bigger, but should pay attention to the brittleness of cutting material can bear or not to avoid chipping.

Therefore, in addition to adjusting the diamond and the anchoring agent, it is necessary to increase cutting speed, enlarge cutting depth and decrease feeding for reducing the crush and shedding of the diamond, as well as the wear of the anchoring agent. This method can enhance cutting efficiency and prolong the lifespan. By contrast, when the diamond has excessive wear resistance, the stone will be ground into a flat or smooth arc surface, and it is hard to produce micro crushing, which means that the anchoring agent matrix is over wear-resistant or it has too much control of the diamond; the cutting depth of the saw blade is large; the feeding is small; the processed material is hard and fine;

Usually, the crush & impact resistance of good quality diamond is better, wearing out slowly and little broken when cutting, so it is very suitable used for cutting strong abrasiveness material like:sandstone, concrete pavement, bituminous pavement, refractory material. In the mean time, Diamond should easy plating,Coarse grit, low Concentration, the bond bond should be high abrasiveness with strong holding force for diamond; the lower grade diamond, cuz the rush & impact resistance is relatively worse,is suitable for cutting easy-cutting material, and the grit should be fine, concentration should be higher, bond should be softer.
