With the Dewalt DT1945-QZ circular saw blade, you can power through tough construction timber, formwork, and reclaimed wood with embedded nails without slowing down. Its 40 impact-resistant carbide teeth easily withstand hidden fasteners, preventing tooth breakage and eliminating frequent blade swaps on demolition or framing jobs. Built-in expansion cooling slots dissipate heat during heavy cuts, reducing binding and blade distortion. Featuring a 190 mm diameter, a 30 mm bore, a positive 10° hook angle, and a 2.6 mm kerf, this blade delivers clean and reliable rip and cross cuts across natural wood and composite boards.
