SET: The bend or spread given to the teeth to
provide clearance for the body or band back when you
make a cut.
SIDE CLEARANCE: The difference between
the dimension of the band back (gauge) and the set of
the teeth. Side clearance provides running room for
the band back in the kerf or cut. Without side

A saw band has the following characteristics
Straight set bands are not used to any great extent to
cut metal.
PITCH: The number of teeth per linear inch.
TEMPER: The degree of hardness of the teeth,
