OPERATION MANUAL
4.5 BLADE SELECTION
Band saw tooth size is determined by the size of the cross section to be cut. In general cutting
thinner sections requires more teeth per inch, thicker sections require coarser pitches, or less
teeth per inch. To select an appropriate tooth size please refer to the table immediately below
unless material to be cut is a tube, in which case refer to the larger table below. For general pur-
pose cutting use a constant pitch blade, for more aggressive production cutting of harder to cut
materials use a variable pitch blade.
