Wire cutters
The wire cutter is a tool for cutting wires . For example, wire ropes are cut with special wire rope cutters.
Difference to cutting pliers
As a rule, wires are cut by pliers ( side cutters, etc.); Cable from cable shears / cable cutters. The difference arises from the shape and the position of the jaws to one another.
With pincers, diagonal cutters, etc., the jaws meet exactly at the end. They are wedge-shaped and cut through even very resistant wire, but the wire is deformed (squeezed) in the process. This process is called wedge cutting .
With scissors, on the other hand, two knives run past each other, making the cut cleaner. In doing so, however, so-called shear forces occur, which change the distance between the cutting surfaces and thus prevent clean cutting. This process is called shear cutting .
Types
What is important is the distance between the jaws, which must be smaller than the piece of metal to be cut or severed. In order to reduce wear, the jaws should have a higher hardness than the material to be cut. Depending on the material to be cut, folding scissors or drop scissors are used.
Folding scissors
Folding scissors have a hinge.
Plumbing shears
With scissors, the two cutting edges run perpendicular to each other like a guillotine. At least one of the two cutting edges of the shears is beveled. Scissors are very suitable for cutting through round objects that should not roll out of the scissors. For example to watch the cigar cutter or the guillotine .
