Tooth pitch
Usually measured as tpi (teeth per inch), tooth
pitch determines the size/number of the teeth.
More teeth per inch (fine pitch) will cut slower,
but smoother; while fewer teeth per inch (coarse
pitch) will cut rougher, but faster.
As a general rule, choose blades that will have at
least three teeth in the material at all times. Use
fine pitched blades on harder metals and coarse
pitched blades on softer metals. When select-
ing blades, refer to
figure 35 for recommended
blade tooth (tpi) and speed (FpM) based on the
workpiece material.
Blade Selection Tooth Style
When selecting blades, another option to con-
sider is the shape, gullet size, teeth set and teeth
angle—otherwise known as “tooth Style." Many
blade manufacturers offer variations of the four
basic styles shown in
figure 36.
Raker (or Standard)
Skip (or Skip Tooth)
Hook (or Claw)
Variable Pitch (VP)
