The DeWalt DT2351‑QZ blades are versatile bi-metal blades crafted for fast, fine cuts in wood—including nail-embedded lumber—and tough plastics. They combine a high-carbon steel (HCS) body with a cobalt-alloyed high-speed steel (HSS) cutting edge for enhanced flexibility, durability, and long life. Their 152 mm length and 4.2 mm pitch (approx. 6 TPI) tooth profile is optimized for curve cuts and detailed work, while the universal ½″ shank ensures compatibility with all major reciprocating saw brands. The Tough Coat anti-stick finish helps reduce friction and pitch buildup for smoother operation.
