What is the best TPI for cutting wood?

A coarse tooth blade (2, 3 TPI) should be used for resawing wood and cutting thicker stock up to 8″. A fine toothed blade (18 to 32 TPI) should be used for thinner metals and plastics under 1/4″. For general cutting of 3/4″ wood 4 TPI will provide a fast cut and 14 TPI will cut slow, but leave a smoother finish.

There are four basic blade types, determined by the shape, or grind, of their teeth. They are flat top grind (FTG), alternate top bevel (ATB), combination (ATBR), and triple-chip grind (TCG) [Figure 1 and Photo A]. FTG blades have teeth whose top edges are square to the saw plate.

How many teeth does a hacksaw blade have?

Blades with densely packed teeth make the smoothest cuts. Typically, these blades are limited to cutting hardwoods 1-1/2 inches thick or less. With so many teeth engaged in a cut, there is a lot of friction. In addition, the small gullets of such closely-spaced teeth eject sawdust slowly.

What saw blade to use for fine cuts?

What is the best saw blade to cut hardwood flooring?

Is more teeth on a saw blade better?
