Features: Segmented Rim - Segmented blades typically have medium to hard bonds for a range of wet and dry cutting applications. these blades offer a relatively smooth cut combined with a fast cutting speed however some chipping may occur. They are durable and have a long blade life compared to other blades. ; The spaces between the segments (gullets) improve air flow, dissipate heat, and remove slurry from the cut, helping to optimise the blade's cutting performance. The size and shape of the gullets vary from blade to blade and will depend on the type of material the blade is designed to cut. ; Diamond blades do not cut, they actually grind through the material by exposing new diamond at the right moment just before the old diamond wears away. The newly exposed diamonds again will wear, chip, or break out of the metal bond in the segment, while the metal bond gradually wears away to expose new diamond. This process is repeated over and over until there is no diamond remaining and the blade is worn out. ; Ideally and to get the maximum life out of a diamond blade, the metal should wear away at just the right time to expose new diamond for optimum cutting performance. ; Specifications:Diameter125 mm / 5"Rim TypeSegmentedSeg Height7 mmBore22.2 mm
