2. Use a larger (thicker) blade more
suitable for the job at hand.
3. Incorrect blade tooth pitch.
3. Choose a blade with more or fewer
teeth per inch (TPI); a minimum of 3
teeth should contact workpiece at all
times.
4. Excessive pressure on blade.
4. Reduce pressure on blade. Let the
tool do the work.
