Size

Both saw blades have a 10” diameter and fit on a 5/8” diameter arbor. Typical table saws have a 5/8” arbor and can take blades up to 10” in diameter. This means both blades should be generally usable on many saws.

The D1012LF cuts a 0.087” (thin) kerf. The 10” x 40T Woodworker II is 0.09” thick and cuts a 1/8” (full) kerf. (The term “kerf” refers to the width of the cut that the blade leaves in the material being cut.)

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

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

Teeth

The D1012LF has 12 polycrystalline diamond teeth. The 10” x 40T Woodworker II has 40 C4 carbide teeth in an ATB configuration.

Blades having a tooth count under 40 are typically meant for ripping wood lengthwise. For crosscuts or general-purpose use, you should consider options with more teeth. Blades having 40 to 60 teeth are usually considered general-purpose blades. They will do an adequate job at rip cuts as well as crosscuts, but not quite as well as a blade designed for those cuts.

Alternate top bevel (ATB) teeth have a sloped shape rather than being straight across. This design allows them to slice through wood rather than chewing out chunks, leading to cleaner crosscuts. ATB teeth do have a tendency to break more frequently than flat-top teeth.
