The package contains two S 2345 X type saw blades for reciprocating saws. The HCS high-carbon steel blades have set, ground teeth with a variable pitch of 2.5 to 4.3 mm and are designed for wood and selected plastics. They are used for structural timber with a thickness of less than 150 mm, chipboard and MDF boards with a thickness of 6 to 60 mm, plywood or plastic under 150 mm. These are wood blades, not bi-metal versions for cutting metal joints.
