With the Dewalt DT20421-QZ circular saw blade, you cut effortlessly and with extreme wear resistance through highly abrasive materials. Featuring a 115 mm diameter, a 9.5 mm bore, and a 1.8 mm kerf width, this blade is equipped with four polycrystalline diamond (PCD) tipped teeth. You achieve clean, precise cuts in fibre cement boards, laminate, and dense composites such as Trespa. The dedicated tooth geometry ensures a significantly longer service life than standard blades and noticeably reduces dust generation on the jobsite.
