DIAMOND BLADE BASICS Edmar Diamond Blade Training Manual 2 What is a Diamond Blade? Continuous Turbo Segmented Edmar Diamond Blade Training Manual 3 What is a Diamond Blade? The blade core is a precision-made steel disc which may or may not have slots. Blade cores are tensioned so that the blade will run straight at the proper cutting speed. Proper tension also allows the blade to remain flexible enough to bend slightly under cutting pressure and then go back to it’s original position. Diamond segments or rims are made up of a mixture of diamonds and metal powders. The diamonds used in bits and blades are man-made (synthetic) and are carefully selected for their shape, quality, friability, and size. These carefully selected diamonds are then mixed with a powder consisting of metals such as cobalt, iron, tungsten, carbide, copper, bronze, and other materials. This mixture is then molded into shape and then heated at temperatures from 1700˚ to 2300˚ under pressure to form a solid metal part called the “bond” or “matrix.” The segment or rim is slightly wider than the blade core. This side clearance allows the cutting edge to penetrate the material being cut without the steel dragging against the sides of the cut. After the blade is assembled it is “opened,” “broken in,” or, “dressed” by grinding the edge concentric to the center. This exposes the diamonds that will be doing the work and establishes the cutting direction as noted by the direction of the arrow stamped into the blade.
