Diablo's next generation 10 -inch x 80 Tooth Non-Ferrous/Plastics Carbide Circular Saw Blade features new laser-cut stabilizer vents for precise and clean cuts in non-ferrous metals and plastic materials. The advanced stabilizer vents feature a permanent filler baked in from top to bottom for absorbing noise and preventing sideways movement, allowing the blade to slice through materials cleanly, quickly and accurately. Constructed with TiCo Hi-Density special-blend carbide, Diablo's 10 -inch non-ferrous metals/plastics blade produces precise cuts and provides 5X longer cutting life. The laser cut heat expansion slots allow the blade to expand and contract during use, keeping the cut true and straight. This blade is excellent for cutting plastics, brass, aluminum, copper and fiberglass.
