General Information
Band Length
The length of a bandsaw blade depends upon the sawing
machine being used. Information for specific machines can
be found in our software
program, BandCalc TM ,
see page 28, or
from your sawing
machine
manufacturer.
Band Width
The band width is measured from the tip of the teeth to the
back edge of the blade.
On horizontal machines, the band width is dependent upon
the bandsaw machine being used. There is, however, some
variation possible on vertical machines.
For contour sawing, the blade should be as wide as the
machine permits, but still narrow enough so that it can be cut
to the desired shape (radius). Please see diagram below.

Types of Set
The set is the tilt, or angle, given to the teeth of the saw
blade to provide clearance for the blade body and the tooth
edges. Below are different types of set:
Raker set
In the raker set, one tooth is set to the left, one tooth is set to
the right, and one tooth (raker) is unset. This set type is
used on most evenly pitched blades such as regular and
hook. It is also used for contour and friction cutting blades
on vertical bandsaw machines.
Combo set
In the combo set, used on combo toothed blades, a raker
(unset) tooth is followed by teeth in a left, right, left, right
sequence. This pattern is repeated with each series of teeth
starting and ending with the largest tooth in the pattern.
