Features and Benefits
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. They are used on ferrous and nonferrous metals.
U-Shanks or universal shank blades are reversible and can be used horizontally for fast and smooth cutting. They are constructed with a U-shaped design.
The cutting surface of a toothed edge is composed of a row of pointed teeth. Common tooth variations include the number of teeth per inch and pitch pattern.
