This Extreme 2nd-Fix blade has a thin 0.99 mm plate and a 1.65 mm kerf, reducing binding and making cuts straighter with less push-force required. The C3-grade carbide teeth can be re-sharpened up to three times, doubling blade life compared to standard construction blades. Ideal for ripping and cross-cutting natural timber, plywood, MDF, and chipboard—just avoid materials with embedded nails
