Size

Both saw blades are 10” in diameter and have a 5/8” arbor hole. Typical table saws have a 5/8” arbor and can accommodate blades up to 10” in diameter. So both products should be generally usable on many saws.

The 10” x 40T PrecisionTrim has a 0.098” (thin) kerf. The 10” x 40T Woodworker II is 0.09” thick and has a 1/8” (full) kerf. (The term “kerf” refers to the width of the cut that the blade makes in the material being cut.)

A 1/8” kerf is called a “full” kerf and ought to work with a wide range of table saws. On lower-powered saws, a full-kerf blade might cause the saw to struggle with thicker or harder material, compared with a thin-kerf blade.

A kerf under 1/8” is called a “thin” kerf. Thin kerfs waste less material than full-kerf blades and make it easier for saws to cut through thick or hard material. Most, but not all, table saws can accept thin-kerf blades. Check that your riving knife is thinner than the kerf, or dangerous binding can occur.

Teeth

Both table saw blades have 40 C4 carbide teeth in an ATB configuration.

Blades with between 40 and 60 teeth are usually viewed as general-purpose blades. They can perform both ripping and crosscutting, but not as well as a blade specifically made for such cuts.

Alternate top bevel (ATB) teeth are cut on a bevel instead of being flat across. This design lets them slice through wood rather than tearing out chunks, leading to cleaner crosscuts. ATB teeth do tend to break more often than flat-top teeth.
