[Professional Reciprocating Saw Blades] The precision honing process makes the reciprocating saw blade very sharp. It can easily cut and separate building materials such as brick, plasterboard, aerated concrete, pumice, Ytong, Poroton and other derivatives of building materials with a thickness of less than 41cm, greatly improving work efficiency. [High hardness saw blade]: The saw body is made of carbon steel, and the saw teeth are made of high-quality alloys. High hardness is not easy to break. Thanks to the generous thickness of the blade and the extra wide tooth pitch. Brick Reciprocating Saw Blades also have a long life and cut fast, coarse and straight [General Reciprocating Reciprocating Saw Blades]: 2TPI Reciprocating Saws and General Reciprocating Saws, including reciprocating saws without wire and common tiger saws; such as Bosch, Metabo, Makita, Einhell, Flex, Festool, Milwaukee, Black & Decker, Skil, Hilti [Wide applications] Suitable for cutting: aerated concrete, red brick, fiber cement (<405 mm / 15.94 inch), glass fiber reinforced plastic, epoxy resin ( <150 mm / 5.90 inch), suitable for abrasive materials. Stone saber saw blades are suitable for wall cutouts and for inserting new doors and windows. It can be used to disassemble aging parts such as building walls, doors and windows. [High precision] 13mm tooth pitch, fast cutting speed; Saw surface thickness: about 1.5mm/0.05inch, saw path width: 5.2mm/0.20inch, suitable for cutting the hardest abrasive materials.
