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.

Type of Blade: Continuous rim. Thinner with finer diamond grit for chip free cutting.
Material being cut: For fast, smooth, chip-free cutting on a wide variety of ceramic tile, quarry tile, and other hard, vitreous material. Great for contractors who consistently cut tile. Razor thin slots with teardrop increases speed for maximum performance on all kinds of ceramic tile, porcelain tile, or stone material. Extra high diamond concentration provides the lowest cost per cut when cutting chip-free. Finer grit, softer bond and higher diamond concentration produces precision cuts on brittle glass tiles.
