The TOPEX circular saw blade combines a trapezoid-shaped leading tooth followed by a flat raker tooth that sits slightly lower. This pattern continues around the whole blade. The blades combine balanced cutting force with low tooth drag and free chip flow. The Circular Saw Blade produces very little chip out and tearout when cutting brittle materials. This makes it a good choice for cutting chipboard (OSB), wood, softwood, particleboard, MDF, hardboard and plywood.
