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 workpiece until it leaves the workpiece, and
2.The shape of the workpiece.
Squares, Rectangles, Flats (Symbol : )
Locate the width of cut on the chart. (Inches on the outer circle and millimeters
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.
Round Sollds (Symbol : )
Locate the diameter of your workpiece 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.
Tubing, Pipe, Structurals( Symbol : O H ^ )
Determine the average width of cut by dividing the area of the workpiece 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.
EXAMPLE: 4"(100mm) outside diameter, 3"(75mm) inside diameter tubing.
4"(100mm) OD =12.5 sq.ln. (79cm
2
)
3"(75 mm ) ID = 7.0 sq.ln. (44cm
2
)
Area = 5.5 sq.ln. (35cm
2
)
5.5 sq.ln. (35cm
2
) / 4" (100mm) distance =1.38(35mm) average width
1.38" (35mm), use a 4/6 Vari-Tooth
