Need to cut through some metal? This 3-pack of reciprocating saw blades has you covered. They're 6 inches long with a 1-inch height and have 10 teeth per inch (TPI). That tooth count is ideal for cutting through various metals – think pipes, nails, bolts, sheet metal, and even some plastics. They have a straight and tapered back design with a universal 1/2-inch shank, so they should fit most standard reciprocating saws (like Sawzalls, Hackzalls, etc.). They're made from a combination of steel and carbide, making them tough and durable for demolition, construction, or automotive work. Each blade has one cutting edge. The pack contains 3 blades, which is handy because these blades can wear out or break, especially on tough jobs. Keep a few spares in your toolbox. Just remember, they're specifically for metal as the primary application, so don't try to cut thick hardwood with them. A practical, no-frills pack for getting the job done.
