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.
