Got some metal cutting to do? These CMT bimetal reciprocating saw blades are built for the job. They're 5 inches long with 18 teeth per inch (TPI), which is ideal for cutting thin sheet metal (like 1/16 to 5/32 inch thick), pipes, and profiles up to about 4 inches in diameter. Made from bimetal (a combo of materials for flexibility and toughness), they've got milled and wave-set teeth that give you a fine, straight cut and last a long time. The kerf (cut width) is 0.035 inches. They come in a handy 5-pack, so you've got extras when one wears out. Perfect for DIY projects, plumbing, auto work, or general metal fabrication. Just make sure your reciprocating saw can handle 5-inch blades, and you're set. Reliable performance from a trusted brand.
