What is the purpose of setting the teeth on a hacksaw blade?

Right Answer is:

To make the cut wider than the blade thickness

SOLUTION

  • The teeth on a hacksaw blade are set (bent) to the left and right, which creates a wider cut than the blade itself.
  • This setting prevents the blade from binding in the material being cut, allowing for smoother operation and reducing the risk of the blade getting stuck or breaking during use.
  • Imagine the hacksaw blade is trying to cut a path through wood or metal.
  • If the blade was perfectly flat, it would get stuck easily because the sides of the cut would rub against the blade.
