Description Don't let dull blades slow down your reciprocating saw. These contractor-rated reciprocating saw blades have reinforced teeth for increased durability, even when slicing through nail-embedded wood and abrasive roof shingles. The 6 hook angle on the teeth creates an extremely aggressive, fast-cutting blade. And its anti-stick coating minimizes friction and reduces sticky buildup.Reinforced tooth for increased durability when cutting through nails and other foreign objectsSpecially formulated anti-stick coating minimizes friction and gum-up for smoother cuts+6Â hook angle for fast, aggressive cutsRaker tooth design increases the tooth contact area for faster cuts
