With the Dewalt DT2421-QZ reciprocating saw blade, you can cut effortlessly and accurately through abrasive masonry materials such as aerated concrete, red brick, poroton, and fiber cement boards up to 250 mm thick. Its durable tungsten carbide-tipped (HM/TCT) teeth deliver outstanding wear resistance during heavy-duty renovation and demolition tasks. The large 12.7 mm tooth pitch (2 TPI) clears debris quickly to ensure rapid cutting progress. In addition, the rigid 305 mm blade body resists bending so you achieve straight, clean cuts every time. Thanks to the universal shank, this S1243HM blade fits standard reciprocating saws from Dewalt, Bosch, Makita, and other brands.
