Product Details
The DeWALT straight back bi-metal reciprocating blade, model DW4821, measures 8 inches in length and features 18 teeth per inch (TPI) with a pack of 5 blades included. It employs a patented tooth design that utilizes sharper tooth geometry for faster cut rates, while an aggressive shank angle increases tooth contact to maintain cutting speed as the blade wears, resulting in longer blade life. Additionally, the blade has a specially formulated anti-stick coating that minimizes friction and gum-up, ensuring smoother cuts.
