Reciprocating saw
A reciprocating saw (also called reciprocating or tiger saw ) is a hand-held electric saw . In contrast to jigsaws , they are mainly used for vertical cuts and are always guided with both hands.
Use and principle of operation
It is driven by an electric motor that drives an eccentric via a gear . A connecting rod runs on this , which converts the rotary motion of the motor into a straight thrust for the saw blade. Simple reciprocating saws typically work with a stroke of 25–28 mm, devices in the upper performance class with up to 32 mm.
Saw blades are available for processing metals, wood, plastic, stone, green waste and ceramic materials . Saw blades with carbide-tipped blades can be used to cut through tree roots in the ground. The saw blade holders of the various manufacturers differ and are not always compatible.
Saber saws are often used by carpenters and builders to dismantle old components, in tree care and by fire brigades and other aid organizations for rescue operations. Plumbing plumbers use them to cut metal pipes. There are guide devices for this purpose that facilitate a straight cut.
According to the current DIN standards, reciprocating saws are mandatory for the fire fighting vehicle types LF 10 , HLF 10 , LF 20 and all HLF 20 as well as for rescue vehicles in Germany.
