Let’s take a look at these two table saw blades: the Forrest 10” x 20T Woodworker II and the Oshlun 10” x 24T ATB.

Features & Benefits

You can read more in our complete guide to buying a table saw blade.

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 table saw blades should be widely compatible with many saws.

Both products have 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 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 24T ATB has 24 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.

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, resulting in 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.
