  • Super sharp teeth cut faster and dulls less
  • Variable depth gullets provide more efficient chip clearance
  • 4/6 variable pitch teeth for reduced noise and improved performance
  • Electron beam weld for stronger, longer lasting teeth
  • Bi-metal construction for toughness and long life
  • Bi-metal blades feature a toothed edge made from high speed steel (HSS) attached to a flexible steel backing through an electron beam welding process
  • This configuration results in a blade that makes precise cuts while resisting breakage
  • Toothed edge saws are composed of a row of pointed teeth
  • Common tooth variations include the number of teeth per inch and pitch pattern
  • HSS provides good wear resistance and can be used in general purpose applications for both ferrous and nonferrous materials
