[Sharp Metal Reciprocating Saw Blades] Due to the precision sharpening process, the reciprocating saw blade is very sharp and can easily cut and separate building materials such as bricks, plasterboard, aerated concrete, pumice, Ytong, Poroton and other derivatives with a thickness of less than 25 cm, greatly improving work efficiency. [High-quality material]: The saw body is made of carbon steel and the saw teeth are made of high-quality alloy with high hardness and are not easy to break. [General reciprocating saw blades]: 2TPI general reciprocating saws and saber saws, including common cordless reciprocating saws and tiger saws; suitable for saws with 0.5-inch universal handles [High precision] 13 mm tooth pitch, fast cutting speed; Saw surface thickness: about 1.5mm/0.05in, saw path width: 5.2mm/0.20in, suitable for cutting the hardest abrasive materials. Thanks to the large blade thickness and very large tooth pitch. The service life of metal reciprocating saw blades is also very
