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 selecting blades, refer to
