The CMT CMT81440 is an 8-1/4" 40-tooth ATB thin-kerf circular saw blade built for contractors who demand smooth, precise cuts in softwood, hardwood, plywood, and OSB. The thin-kerf design reduces cutting resistance for faster, more accurate cuts with less vibration — and the expansion slots prevent warping during high-speed rotation.

Rated at 8,500 RPM with a 20° hook angle and ATB (10°) grind, the CMT81440 is compatible with portable and cordless circular saws, making it a versatile choice for framing, decking, and general construction.
