Timberline 640-210 Turbo Diamond 4-1/2 Inch D 7/8 Bore, Circular Diamond Saw Blade
Ideal for cutting concrete, brick, pavers, slate, granite and marble.
These diamond saw blades are sintered with a serrated cutting edge to stay in constant contact with the material and produce a smoother cut than the segmented blades. They have a longer life than the continuous rim blades. They are circular steel blades with diamond impregnated grit on the rim. The rims contain a mixture of metal powder, diamond powders and industrial diamonds of different sizes and qualities, depending on the different types of material to be cut.
The individual diamond crystals exposed on the edge and sides of the rim do the cutting. The operator pushes the rotating blade into the surface of the material, causing the diamonds to cut a groove in the material. While the blade cuts, the material exerts wear on the blade exposing the diamond grit on the rim. This causes the diamond grit to wear away and expose more diamond grit underneath, thus grooving the material. The more abrasive the material the faster the tendency to wear down the rim. Always read and follow the operating and safety instructions in the power tool owner’s manual before using.
