Band Saw How To's
|
The
most commonly used tooth shape. Ideally suited for both cut-off
and contour sawing of most materials. For cutting thin materials
where a fine cut is required.
Widely
spaced teeth with a 0° rake angle to
prevent clogging when cutting soft, non-ferrous metals, plastics
and wood. 
Positive
10° rake angle helps to "digin",
resulting in a higher cutting rate. Recommended for long
cuts into thicker wood, plastic and metal. 
The raker tooth set consists of one to the
left, one to the right and one tooth (raker) is unset. This
set is used for cutting thick, solid metal sections on horizontal
cut-off machines. It is also used for contour cutting and resawing
on vertical band machines. 
Alternate
set or double alternate plus raker set blades are designed
for cutting wood. Provides faster, smoother cuts. 
This
set pattern has groups of teeth set to the left and to the right,
separated by unset raker teeth. It is made primarily with small
teeth and is recommended for cutting thinner sections - tubes,
pipes, thin sheets and other small shapes. 32 TPI only.
