Bi-Metal Speeds And Feeds - Promac SX-824DG Mode D'emploi

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
3"(75 mm ) ID = 7.0 sq.ln. (44cm
Area = 5.5 sq.ln. (35cm
5.5 sq.ln. (35cm
distance =1.38(35mm) average width
1.38" (35mm), use a 4/6 Vari-Tooth
NOTE: The band speed and cutting rate
recommendations presented on this chart are
approximations and are to be used as a
starting point for most applications. For exact
sawing parameters' consult your saw blade
supplier.
