Diablo's next generation 10 in. x 40-Tooth General Purpose and 10 in. x 60-Tooth Fine Finish Carbide Circular Saw Blades feature new laser-cut stabilizer vents for precise and clean cuts in a variety of wood 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 wood cleanly, quickly and accurately. Constructed with TiCo Hi-Density special-blend carbide, Diablo's 10 in. x 40-Tooth general purpose blade produces razor sharp cuts, while the 10 in. x 60-Tooth fine finish blade produces precise cuts and both blades offer up to 5X longer cutting life. The laser cut heat expansion slots allow the blades to expand and contract during use, keeping the cut true and straight. This 40-tooth blade is excellent when working on projects such as decking, framing and building furniture and the 60-tooth blade is excellent for trim work and projects such as building bookcases, cabinets and shelving.
