Diablo Trex Blade Decking Circular Saw Blade Composite decking circular saw blade specifically designed for cutting composite materials. Saw blade has modified triple chip tooth grind design which enables the composite material to remain cool while cutting, creating melt-free cuts and no swirl marks. Perma-Shield non-stick coating reduces drag and shields the blade against heat, gumming and corrosion. TiCo Hi-Density carbide maximizes cutting life in composite materials and plastics. Blade has a super thin-kerf design, which requires less cutting power. Laser-cut stabilizer vents absorb noise and vibration keeping the blade straight and true for superior quality cuts.
