DEWALT DW4809 8-Inch 14 TPI Straight Back Heavy-Gauge Bi-Metal Reciprocating Saw Blade, 5-Pack
The DeWalt DW4809 8-inch 14 TPI straight back bi-metal reciprocating saw blade is a tough blade that's built for cutting in heavy-gauge metal, hard rubber, fiberglass, and angle iron. This straight-back blade can also be used to cut a wide variety of materials, including wood, plastic, and drywall. In general, a lower tooth count cuts faster, but provides a rougher finish, and this 14 TPI (Teeth Per Inch) blade is no different. Each DW4809 features bi-metal construction with reinforced teeth for increased durability, anti-stick coating for reduced friction, and matrix II steel with 8-percent cobalt for longer blade life. In addition, this reciprocating blade features a +/- 3-degree shank angle for aggressive cuts, a raker tooth design for increased tooth contact area, and a patented tooth geometry for faster cut rates. Built from the toughest materials, the blade body is durable, yet flexible to reduce breaking. This all-purpose blade (sold in a pack of 5) will fit all brands of reciprocating saws.
