We’ve also got a roundup of the best 10” table saw blades.

Size

Both saw blades are 10” in diameter and have a 5/8” arbor hole. Most table saws have a 5/8” arbor and can accommodate blades up to 10” in diameter. So both products should be widely compatible with many saws.

Both table saw blades have a 1/8” (full) kerf. The 10” x 40T Woodworker II is 0.09” thick. (The term “kerf” refers to the width of the cut that the blade makes in the material being cut.)

A 1/8” kerf is considered a “full” kerf and should work with most 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.

Teeth

The 10” x 20T Woodworker II has 20 teeth in an ATBR (2+1) configuration. The 10” x 40T Woodworker II has 40 C4 carbide teeth in an ATB configuration.

Blades with fewer than 40 teeth are usually geared towards ripping wood lengthwise. For crosscuts or general-purpose use, you might consider blades with a higher tooth count. Blades with between 40 and 60 teeth are generally considered general-purpose blades. They will be adequate for both ripping and crosscutting, but not quite like a blade specifically made for those cuts.

Alternate top bevel (ATB) teeth are cut on a bevel rather than being flat across. This shape lets them slice through wood rather than tearing out chunks, leading to cleaner crosscuts. They do tend to be less durable than flat-top teeth. Alternate top bevel/raker (ATBR) blades have flat-top “raker” blades interspersed every few teeth, to help improve performance when ripping. They also leave a flat bottom on non-through cuts, rather than the parallel grooves of a regular ATB blade.
