The CMT Contractor CMT81440 8-1/4" 40-Tooth Circular Saw Blade is built for contractors who need smooth, precise cuts in soft/hardwood, plywood, and OSB on every job. Its thin-kerf design (0.063" kerf / 0.039" plate) reduces material waste and demands less power from your saw, while the 20° hook angle and 10° ATB grind deliver clean, accurate results. Expansion slots prevent warping during rotation and dampen vibration for a steadier cut, and constructional carbide cutting edges extend blade life well beyond standard blades. Rated at 8,500 Max RPM, it’s compatible with portable and cordless circular saws.
