When rectangular solid bar is to be sawed, the work should whenever possible be loaded with the thinnest cross section exposed to the blade teeth. The picth (or number of teeth per inch of blade) selected must provide engagement of at least 3 teeth in the wprkpiece. Should application of this rule not be possible because the thinnest cross section is too thin, the piece must be loaded with the wider dimention exposed to the saw teeth and a coarser blade selected from the listing of recommendation for round and square solid bars.
