This Hitachi Fiber Cement Circular Saw Blade has a 10-inch diameter and is made for use with most 10-inch miter saws. This blade has a 5/8-inch arbor, and its special 6-tooth design provides precise, dust-reducing cuts. The blade’s highly durable polycrystalline diamond tips provide 5 times longer cutting life than other diamond-tipped blades and 30 times longer cutting life than traditional carbide blades. The polycrystalline diamond tips also have self-sharpening properties. This blade is ideal for ripping, crosscutting, and mitering in fiber cement boards and siding.
