How to choose a saw based on teeth per inch?

TPI is an acronym for Teeth Per Inch and is measured from gullet to gullet, not tooth tip to tooth tip.
In general, a saw with more teeth per inch cuts slower but leaves a cleaner finish; a saw with less teeth per inch cuts faster but leaves a rougher finish. Besides, the more teeth per inch a saw has, the harder materials the saw can cut through.

Coarse teeth

A bow saw is an example of a saw which have a low TPI. Bow saw blades often have 5 teeth per inch and are used for quickly cutting tree branches or roughly sawing into logs.

Due to they have lower teeth per inch, they are very suitable for cutting that doesn't need a smooth surface.

Medium teeth

Generally, the middle teeth are 7 teeth per inch of the saw blade. These types of saw blades are usually used for wood or general cutting.

Blades with medium TPI can make a balance between fast cutting and slow. If used correctly, they will cut through the material fairly quickly and create a relatively neat surface.


The more teeth of the blades, the smaller of cutting wide, the slower of cutting speed. It is very suitable for precision cutting that needs to have straight and curved lines in wood.

A hacksaw and a coping saw are an example with more teeth per inch. They have 18TPI and 32TPI and more controlled cut in wood allowing for more detailed cuts.
