Features:

• 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
• 3-1/2 in pipe tap
