Timberline 640-340 Segmented Rim Diamond 7-7-1/4 Inch D 5/8 Bore with 7/8" Diamond knockout, Circular Diamond Saw Blade
Ideal for cutting concrete block, concrete, concrete pavers and slate.
These blades provide the longest life at the lowest cost per cut. The segmented gullets provide faster, cleaner and cooler cuts. These blades should be used where chipping is not a problem. 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.
