Tork Craft Diamond Blade 350x25.4mm Laser Ind. Duty

The individual diamond crystals exposed on the leading edge and the sides of the segment or rim carry out the cutting. The operator pushes the rotating blade into the material and the surface diamonds thus exposed mill a groove in the material. When the blade mills the material, the latter exerts wear on the blade. During cutting the exposed diamonds may crack or break. The material simultaneously starts to abrade the metal matrix, which releases more diamonds. The more abrasive the material, the more rapid the tendency to wear down the matrix. Blades for cutting hard, denseless abrasive materials (such as tile, bricks, stone or cured concrete), require a softer metal matrix. This will wear down faster, replacing the worn diamonds fairly quickly so that the blade continues to cut. Blades for cutting soft, abrasive materials (such as green concrete and asphalt), must have a hard, abrasion-resistant metal matrix in order to retain the diamonds for a longer time.
