Friction Band Saw Blades-Special silicon carbon steel with good abrasion resistance and flex life is used for the manufacture of Friction cutting bandsaw blades. 

How does Friction bandsawing work?

1.  Material is held to a fast moving welded to length saw blade typically running between 6,000-18,000 f.p.m).

2.  The high frictional heat created allows the band saw blade to burn or melt away the material while the bandsaw blade teeth remove the molten metal from the work piece. 

3.  Since any given part of the band saw blade is out of contact with the metal being cut 99% of the time, the bandsaw blade itself remains cool to the touch.  It is important to note that friction band sawing has solved many difficult metal cutting problems, but it has distinct limitations imposed by the size and thicknesses of the work pieces.  Thicknesses over 3/4" are extremely difficult to friction cut.  Very thin or odd shaped metals may be successfully cut by friction sawing when conventional methods fail. Friction sawing creates very little drag, so the irrecular shapes can be held win the hands of the band saw operator and turned freely for trimming.  The most typical materials cut using the friction sawing method are:
