SOME SAWING PRACTICES
Saw Pitch Selection
Sawing “Rules of Thumb”:
1. The thinner the stock, the finer the saw pitch.
2. The thicker the stock, the coarser the saw pitch.
3. The more difficult the stock, the finer the saw pitch.
4. The softer the material , the coarser the saw pitch.
Always have at least three teeth in contact with the material being cut.
Material Size and Saw Pitch
Anytime during the cutting operation, at least three teeth must be in contact with the material being
cut. Figure 7.4 shows some sawing practices:
