Saws

Sawing can be made to make precise cuts through many materials and is usually an initial step in parts production. Saws are tools with a single row of teeth in a line and can be of many several types, they can be used in specific machines such as band saw machines or used in hand held tools such as hand hack saws. In all cases the cutting edges of the tools are made of High-Speed Steel or ASP® due to the good cutting properties, but the rest of the saw could be of a less wear resistant more tough material called a backing material.

High-Speed Steels for Bimetal Saw

Bi-metal saws are the largest group of saws, where a wire of ASP® is welded onto a backing material. This way of producing saws allows for the cutting teeth to be even harder and more wear resistant than compared to saws made entirely of High-Speed Steel.

Applications of bimetal saws include:

  • band saws
  • hole saws
  • hand hack saws
  • jigsaws
  • tiger saws

High-Speed Steels for other Saw

A  distinction between saws is the group of saws that only run in one direction such as band saws and saws that reciprocates such as hand hack saws. Reciprocating saws need significantly higher toughness compared to other saws, as they only cut the material in one direction. The non-reciprocating saws use the high achievable wear resistance, hardness and drawability of the ASP® to get good performance in the cutting operation.

The highest performance for saws can be achieved with ASP® grades such as ASP® 2042 and ASP® 2051.
