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

files, and polishing bands.
Raker set bands are generally used for solid cross
section work. Wave set bands are used to cut hollow
materials, such as pipe and tubing, and for other work
where there is a great deal of variation in thickness.
A saw band has the following characteristics
Straight set bands are not used to any great extent to
PITCH: The number of teeth per linear inch.
TEMPER: The degree of hardness of the teeth,

GAUGE: The thickness of the band back. This
measurement is expressed in thousandths of an inch.
