The DeWalt DT20438-QZ 305mm 6TPI Carbide Reciprocating Saw Blade is the ideal blade for completing rapid and accurate cuts in metal applications. The blade is coated with titanium, which awards the teeth increased wear resistance and allows them to stay sharper. The blade has a larger gullet when compared to bi-metal blades, which removes material much faster and decreases cutting time. The carbide teeth are precision ground, and the blade is ideal for tough demolition applications.
