Round Solids (Symbol:
●
)
Locate the diameter of your work piece on the chart. Select the tooth pitch on the ring
marked with the circle which aligns with the size of stock you are cutting.
Example: 4” (100mm) round, use a 3/4 Vari-Tooth.
•
Tubing, Pipe, Structural (Symbols: 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. Select the tooth pitch 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.

BLADE SPEED
The band speeds are to be used as a starting point for most application. For exact parameters
consult your saw blade supplier.

TELLTALE CHIPS
Chips are the best indicator of correct feed force. Monitor chip information and adjust feed
accordingly.
Thin or powdery chips
– increase feed rate or reduce band speed.
Burned heavy chips
– reduce feed rate and/or band speed.
Curly silvery and warm chips
– optimum fed rate and band speed.
