Tooth form
Figure 32 shows common blade forms. Tooth form
has an effect on cutting rate.
Regular:
Standard blade form with evenly spaced
teeth and zero-degree rake angle. Offers clean cuts
at slower feed rates.
Skip Tooth:
More space between teeth, for good
chip removal and fast cuts.
Double Tooth:
A skip tooth with larger gaps
between tooth sets; good chip removal, fast cutting.
Reverse Tooth:
Prevents underside tear-out,
leaves clean edge.
Spiral:
Cuts on all sides without turning workpiece;
limited applications but good for looser fretwork.
Crown Tooth:
Cuts on both up and down strokes
for clean, splinter-free edges. Depending on blade
oscillation settings, a crown tooth blade may often
be turned over for a fresh set of cutting teeth.
