6. MAKE PROPER TOOTH SELECTION
For maximum cutting efficiency and lowest cost per cut, it is important to select the blade with the
right number of teeth per inch (TPI) for the material being cut. The material size and shape dictate
tooth selection.
TOOTH
SELECTION
You need to consider:
1. The width of the cut . That is, the distance in the cut that each tooth must travel from the point it
enters the work piece until it leaves the work piece, and
2.The shape of the work piece.
l
Squares, Rectangles, Flats (Symbol :

)
Locate the width of cut on the chart. (Inches on the outer circle and millimetres on the
inner circle.) Select the tooth pitch on the ring marked with the square shape which
aligns with the width of cut.
EXAMPLE: 6" (150mm) square, use a 2/3 Vari-Tooth.
l
Round Solids (Symbol :
●
)
Locate the diameter of your work piece on the chart. Select the tooth pitch on the ring
marked with the round shape which aligns with the size of stock you are cutting.
EXAMPLE: 4" (100mm) round, use a 3/4 Vari-Tooth.
l
Tubing, Pipe, Structural (Symbol : O H ^)
Determine the average width of cut by dividing the area of the work piece by the
distance the saw blade must travel to finish the cut. Locate the average width of cut on
the chart. Select the tooth Ditch on the ring marked with the tubing and structural shape
which aligns with the average width you are cutting.
