These blades feature a combination of one flat-top tooth followed by a pair of alternating top bevel teeth - the ideal combination for accurate, efficient cuts with hand-held saws. The teeth are ground from a special carbide that stands up well to the occasional nail or other imperfection you encounter in harsh construction environments. CMT's thin kerf blades put far less load on your saw than conventional blades, delivering faster cuts and longer life for the blade and saw. Every ITK blade includes all of our latest design features, including Anti-Kickback Design, Tri-Metal Brazing, and Laser Cut Arbors and Plates.
